RESUMEN
OBJECTIVES: Technical graft loss, usually thrombotic in nature, accounts for most of the pancreas grafts that are removed early after transplant. Although arterial and venous thrombosis can occur, the vein is predominantly affected, with estimated overall rate of thrombosis of 6% to 33%. In late diagnosis, the graft will need to be removed because thrombectomy will not restore its functionality. However, in early diagnosis, a salvage procedure should be attempted. MATERIALS AND METHODS: We conducted a retrospective, descriptive analysis of a prospective database of patients who underwent pancreas transplant from April 2008 to June 2020 at a single center. We evaluated post-transplant clinical glucose levels, imaging, treatment, and outcomes. We also performed a systematic review of publications for endovascular treatment of vascular graft thrombosis in pancreas transplant. RESULTS: In 67 pancreas transplants analyzed, 13 (19%) were diagnosed with venous thrombus. In 7 of 13 patients (54%), systemic anticoagulation was prescribed because of a non-occlusive thromboses, resulting in complete resolution for all 7 patients. Six patients (46%) required endovascular thrombectomy because of the presence of complete occlusive thrombosis; 4 of these patients (67%) needed a second procedure because of recurrence of the thrombosis. One of the 6 patients (17%) required a surgical approach, resulting in successful removal of the recurrent clot. Twelve of the 13 grafts (92%) were rescued. Graft survival at 1 year was 84%; graft survival at 3, 5, and 10 years remained at 70%. CONCLUSIONS: Pancreas vein thrombosis represents a frequent surgical complication and remains as a challenging problem. In our experience, early diagnoses and an endovascular approach combined with aggressive medical treatment and follow-up can be used for successful treatment and reduce graft loss.

BACKGROUND: While bibliometric analyses are prevalent in the medical field, few have focused on ther endovascular treatment for acute ischemic stroke (AIS). OBJECTIVE: To employ big data analysis to examine the research status, trends, and hotspots in endovascular treatment for AIS. METHODS: We conducted a comprehensive search using the Web of Science (WOS) database to identify relevant articles on the endovascular treatment for AIS from 1980 to the present. We used various tools for data analysis, including an online platform (https://bibliometric.com/app), the Citespace software, the Vosviewer software, and the ArcMap software, version 10.8. A number of bibliometric indicators were collected and analyzed, such as publication date, country where the studies were conducted, institutions to which the authors were affiliated, authors, high-frequency keywords, cooperative relationship etc. RESULTS: A total of 5,576 articles were retrieved. A substantial increase in the number of articles occurred after 2010. High-frequency keywords included terms such as large vessel occlusion, reperfusion, outcome, and basilar artery occlusion. Among the top 10 most productive authors, Raul G. Nogueira ranked first, with 136 published articles. Among the journals, The New England Journal of Medicine ranked first, with 5,631 citations. The United States has the closest collaborative ties with other nations. CONCLUSION: In the present study, we found that the reports of endovascular treatment for AIS gradually increased after 2010. Among them, Raul G. Nogueira was the most productive author in this field. The New England Journal of Medicine was the most cited, and it had the greatest impact. The Multicenter Randomized Clinical Trial of Endovascular Treatment of Acute Ischemic Stroke in the Netherlands (MR CLEAN) trial study was the most cited, and it was a landmark study. There are many interesting studies on endovascular treatment for AIS, such as ischemic penumbra, collateral circulation, bridging therapy etc.

Regarding intracranial aneurysm treatment, the clip versus coil debate remains inconclusive and lacking studies in Brazil. To examine trends in the management of intracranial aneurysms in Brazil over time, both ruptured and unruptured. A descriptive and exploratory study was conducted based on data of neurovascular procedures for aneurysm treatment using the Brazilian Public Health System database (DATASUS). The variables analyzed were the number of procedures, mortality rates, length of hospital stays, and global costs of hospitalization, from 2010 to 2019. Temporal trend analysis and statistical comparisons were conducted to assess changes over time and differences between the treatment options. The mean annual number of aneurysm treatments with endovascular embolization was 2206.30 (± 309.5), with a non-significant increasing trend (B = 55.66; p = 0.104). Conversely, microsurgical clipping exhibited a significant decreasing trend (B = -69.97; p < 0.001) with a mean of 1133.1 (± 223.12) procedures. The mortality rate associated with clipping procedure was higher in the period, with a mean difference of 5.23 (± 0.39); ([CI95%: 4.36; 6.10]; p < 0.001) and showed an increase trend, while embolization showed a stable trend. The length of in-hospital stay remained stable for clipping but increased for embolization. Costs associated with clipping increased over time, whereas costs for embolization decreased. This study highlights a significant shift in the treatment of aneurysm towards Endovascular Embolization. Despite higher costs, endovascular procedures were associated with lower mortality rates and shorter hospital stays. These findings provide valuable insights into aneurysm treatment patterns and indicators in a middle-income country's Public Health System.

BACKGROUND: Postoperative myocardial infarction (POMI) is associated with major surgeries and remains the leading cause of mortality and morbidity in people undergoing vascular surgery, with an incidence rate ranging from 5% to 20%. Preoperative coronary interventions, such as coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCI), may help prevent acute myocardial infarction in the perioperative period of major vascular surgery when used in addition to routine perioperative drugs (e.g. statins, angiotensin-converting enzyme inhibitors, and antiplatelet agents), CABG by creating new blood circulation routes that bypass the blockages in the coronary vessels, and PCI by opening up blocked blood vessels. There is currently uncertainty around the benefits and harms of preoperative coronary interventions. OBJECTIVES: To assess the effects of preoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery. SEARCH METHODS: We searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE Ovid, Embase Ovid, LILACS, and CINAHL EBSCO on 13 March 2023. We also searched the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) or quasi-RCTs that compared the use of preoperative coronary interventions plus usual care versus usual care for preventing acute myocardial infarction during major open vascular or endovascular surgery. We included participants of any sex or any age undergoing major open vascular surgery, major endovascular surgery, or hybrid vascular surgery. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes of interest were acute myocardial infarction, all-cause mortality, and adverse events resulting from preoperative coronary interventions. Our secondary outcomes were cardiovascular mortality, quality of life, vessel or graft secondary patency, and length of hospital stay. We reported perioperative and long-term outcomes (more than 30 days after intervention). We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS: We included three RCTs (1144 participants). Participants were randomised to receive either preoperative coronary revascularisation with PCI or CABG plus usual care or only usual care before major vascular surgery. One trial enrolled participants if they had no apparent evidence of coronary artery disease. Another trial selected participants classified as high risk for coronary disease through preoperative clinical and laboratorial testing. We excluded one trial from the meta-analysis because participants from both the control and the intervention groups were eligible to undergo preoperative coronary revascularisation. We identified a high risk of performance bias in all included trials, with one trial displaying a high risk of other bias. However, the risk of bias was either low or unclear in other domains. We observed no difference between groups for perioperative acute myocardial infarction, but the evidence is very uncertain (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.02 to 4.57; 2 trials, 888 participants; very low-certainty evidence). One trial showed a reduction in incidence of long-term (> 30 days) acute myocardial infarction in participants allocated to the preoperative coronary interventions plus usual care group, but the evidence was very uncertain (RR 0.09, 95% CI 0.03 to 0.28; 1 trial, 426 participants; very low-certainty evidence). There was little to no effect on all-cause mortality in the perioperative period when comparing the preoperative coronary intervention plus usual care group to usual care alone, but the evidence is very uncertain (RR 0.79, 95% CI 0.31 to 2.04; 2 trials, 888 participants; very low-certainty evidence). The evidence is very uncertain about the effect of preoperative coronary interventions on long-term (follow up: 2.7 to 6.2 years) all-cause mortality (RR 0.74, 95% CI 0.30 to 1.80; 2 trials, 888 participants; very low-certainty evidence). One study reported no adverse effects related to coronary angiography, whereas the other two studies reported five deaths due to revascularisations. There may be no effect on cardiovascular mortality when comparing preoperative coronary revascularisation plus usual care to usual care in the short term (RR 0.07, 95% CI 0.00 to 1.32; 1 trial, 426 participants; low-certainty evidence). Preoperative coronary interventions plus usual care in the short term may reduce length of hospital stay slightly when compared to usual care alone (mean difference -1.17 days, 95% CI -2.05 to -0.28; 1 trial, 462 participants; low-certainty evidence). We downgraded the certainty of the evidence due to concerns about risk of bias, imprecision, and inconsistency. None of the included trials reported on quality of life or vessel graft patency at either time point, and no study reported on adverse effects, cardiovascular mortality, or length of hospital stay at long-term follow-up. AUTHORS' CONCLUSIONS: Preoperative coronary interventions plus usual care may have little or no effect on preventing perioperative acute myocardial infarction and reducing perioperative all-cause mortality compared to usual care, but the evidence is very uncertain. Similarly, limited, very low-certainty evidence shows that preoperative coronary interventions may have little or no effect on reducing long-term all-cause mortality. There is very low-certainty evidence that preoperative coronary interventions plus usual care may prevent long-term myocardial infarction, and low-certainty evidence that they may reduce length of hospital stay slightly, but not cardiovascular mortality in the short term, when compared to usual care alone. Adverse effects of preoperative coronary interventions were poorly reported in trials. Quality of life and vessel or graft patency were not reported. We downgraded the certainty of the evidence most frequently for high risk of bias, inconsistency, or imprecision. None of the analysed trials provided significant data on subgroups of patients who could potentially experience more substantial benefits from preoperative coronary intervention (e.g. altered ventricular ejection fraction). There is a need for evidence from larger and homogeneous RCTs to provide adequate statistical power to assess the role of preoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery.

INTRODUCTION: Small and very small anterior communicating artery (ACoA) aneurysms pose a complex challenge in neurosurgery and interventional neuroradiology due to their critical location and potential for severe consequences upon rupture. Surgical clipping has been a traditional approach, but it presents challenges requiring precision and expertise. Endovascular treatment has emerged as an alternative, offering minimally invasive techniques with potential advantages. This study aims to comprehensively compare outcomes and efficacy between surgical clipping and endovascular treatment for small or very small ACoA aneurysms. OBJECTIVES: We aimed to perform a meta-analysis of small or very small anterior communicating artery aneurysms comparing surgical clipping and endovascular treatments. METHODS: A systematic review and meta-analysis were conducted, including studies reporting on both treatment modalities. Eligible studies were identified through PubMed, Cochrane Library, and Embase databases. Pooled analyses with 95% confidence intervals were used to compare treatment effects, and statistical analysis followed PRISMA guidelines. RESULTS: Thirteen studies with 637 patients were included. Endovascular treatment, predominantly coiling, was performed in 60.3% of patients, while 39.7% underwent surgical management. Endovascular treatment exhibited an 18% retreatment rate, contrasting with 0% in the surgery group. Mortality rates were 3% and 6% for endovascular and surgical treatments, respectively. Overall complications occurred in 1.8% of patients, with intraoperative rupture and cerebral infarction being the most common. CONCLUSION: In summary, our study indicates a comparable outcome between surgical clipping and endovascular treatment for small ACoA aneurysms, with the former showing a lower retreatment rate. Decision factors include surgeon expertise, healthcare context, and patient age. Further research is needed to refine treatment strategies, considering variations in aneurysm status and evolving techniques.

BACKGROUND: Sigmoid sinus wall dehiscence can lead to pulsatile tinnitus with a significant decrease in quality of life, occasionally leading to psychiatric disorders. Several surgical and endovascular procedures have been described for resolving dehiscence. Within endovascular procedures, the sagittal sinus approach could be a technical alternative for tracking and accurate stent positioning within the sigmoid sinus when the jugular bulb anatomy is unfavorable. CASE PRESENTATION: A retrospective case series of three patients with pulsatile tinnitus due to sigmoid sinus wall dehiscence without intracranial hypertension was reviewed from January 2018 to January 2022. From the participants enrolled, the median age was 50.3 years (range 43-63), with 67% self-identifying as female and 33% as male. They self-identified as Hispanic. Sigmoid sinus dehiscence was diagnosed using angiotomography, and contralateral transverse sinus stenosis was observed in all patients. Patients underwent surgery via a navigated endovascular sagittal sinus approach for sigmoid sinus stenting. No neurological complications were associated with the procedure. Pulsatile tinnitus improved after the procedure in all patients. CONCLUSIONS: Superior sagittal sinus resection for sigmoid sinus wall stenting is a safe and effective technique. Pulsatile tinnitus due to sigmoid sinus wall dehiscence could be treated using the endovascular resurfacing stenting technique. However, further research is needed to evaluate the potential benefit of contralateral stenting for removing sinus dehiscence when venous stenosis is detected. However, resurfacing sigmoid sinus wall dehiscence results in symptomatic improvement.

PURPOSE: To describe a single-center experience with robotic-assisted endovascular treatment for transplant renal artery stenosis. MATERIALS AND METHODS: This is a single-center, retrospective, feasibility study of 4 consecutive cases of robotic-assisted endovascular surgery for transplant renal artery stenosis from October 2021 to August 2022. RESULTS: All lesions were identified, and stenting was performed with no complications. Conversion to manual control was not necessary. The mean fluoroscopy time was 25.25 min (range 12-60.9). A control Doppler ultrasound was routinely performed, demonstrating no residual lesions in all cases. There was no reintervention during the follow-up period. The operator learning curve was felt to be acceptable. CONCLUSION: Robotic-assisted endovascular treatment is a feasible technique for transplant renal artery stenosis.

Dural Arteriovenous Fistulas (dAVFs) of the anterior cranial fossa (ACF) are uncommon but carry a high risk of hemorrhage and pose substantial treatment challenges. Recent advancements in endovascular treatment (EVT), including the introduction of novel liquid embolic agents, have markedly bolstered EVT's role in managing ACF-dAVFs, with notable series published in the last five years. We aimed to assess the feasibility, safety, and efficacy of EVT for ACF-dAVFs. We searched Medline, Scopus, Web of Science, and Cochrane Library databases following PRISMA guidelines. Eligible studies included those with ≥ 5 patients undergoing embolization of ACF-dAVFs, detailing both angiographic and clinical outcomes. We used single proportion analysis with 95% confidence intervals under a random-effects model, I2 to assess heterogeneity, and Baujat and sensitivity analysis to address high heterogeneity. Publication bias was assessed by funnel-plot analysis and Egger's test. Outcomes included complete occlusion following embolization, unsuccessful endovascular embolization attempts, incomplete occlusion following embolization, symptom resolution or clinical improvement following embolization, recurrence; procedure-related complications, morbidity, and mortality. Additionally, a subanalysis for studies exclusively utilizing Onyx™ embolic system was done. Eighteen studies comprising 231 ACF-dAVF were included. Unsuccessful endovascular embolization attempts rate was 2%. Complete occlusion rate was 85%, with 4% of complications. Incomplete occlusion rate was 10%. Successfully embolized patients experienced either symptom resolution or clinical improvement in 94% of cases. Morbidity and mortality rates were 1% and 0%, respectively. Onyx subanalyses showed an overall rate of 0% for unsuccessful attempts, 95% for complete occlusion, and 5% for incomplete occlusion. Symptom resolution or clinical improvement was 98% and recurrence rate was 0%. EVT for ACF-dAVF is highly feasible, effective, and safe, with a low rate of complications, morbidity, and mortality. The subanalyses focusing on Onyx embolizations revealed superior efficacy and safety outcomes compared to the findings of the primary analyses involving all included studies.

Ruptured anterior communicating artery (ACoA) aneurysms are frequently associated with neuropsychological deficits. This review aims to compare neuropsychological outcomes between surgical and endovascular approaches to ACoA. We systematically searched PubMed, Embase, and Web of Science for studies comparing the endovascular and surgical approaches to ruptured ACoA aneurysms. Outcomes of interest were the cognitive function, covered by memory, attention, intelligence, executive, and language domains, as well as motor and visual functions. Nine studies, comprising 524 patients were included. Endovascularly-treated patients showed better memory than those treated surgically (Standardized Mean Difference (SMD) = -2; 95% CI: -3.40 to -0.61; p < 0.01). Surgically clipped patients had poorer motor ability than those with coiling embolization (p = 0.01). Executive function (SMD = -0.20; 95% CI: -0.47 to 0.88; p = 0.55), language (SMD = -0.33; 95% CI: -0.95 to 0.30; p = 0.30), visuospatial function (SMD = -1.12; 95% CI: -2.79 to 0.56; p = 0.19), attention (SMD = -0.94; 95% CI: -2.79to 0.91; p = 0.32), intelligence (SMD = -0.25; 95% CI: -0.73 to 0.22; p = 0.30), and self-reported cognitive status (SMD = -0.51; 95% CI: -1.38 to 0.35; p = 0.25) revealed parity between groups. Patients with ACoA treated endovascularly had superior memory and motor abilities. Other cognitive domains, including executive function, language, visuospatial function, attention, intelligence and self-reported cognitive status revealed no statistically significant differences between the two approaches.

BACKGROUND: Endovascular treatment of intracranial aneurysms (EVTIAs) is increasingly popular due to its minimally invasive nature and high success rate. While general anesthesia (GA) has been the historical preference for EVTIAs, there's growing interest in local anesthesia (LA). However, concerns persist about LA safety for EVTIAs. Therefore, we conducted a systematic review and meta-analysis to assess LA safety for EVTIAs. METHODS: Following PRISMA guidelines, we searched PubMed, Embase, and Web of Science databases. Pooled analysis with 95 % confidence intervals (CI) assessed effects, I2 statistics gauged heterogeneity, and a random-effects model was adopted. Conversion to GA, neurological or procedure-related complications, intraoperative intracranial hemorrhagic complications (IIHC), and mortality were assessed. Subanalyses for ruptured and unruptured cases were performed. RESULTS: The analysis included eleven studies, 2,133 patients, and 2,369 EVTIAs under LA. Conversion to GA rate was 1 % (95 %CI: 0 to 2 %). Neurological or procedure-related complications rate was 13 % (95 % CI: 8 % to 17 %). IIHC analysis revealed a rate of 1 % (95 % CI: 1 % to 2 %). The mortality rate was 0 % (95 %CI: 0 % to 0 %). Subanalyses revealed similar rates in ruptured and unruptured subgroups, except for a slightly high rate of complications and IIHC in the ruptured subgroup. CONCLUSION: Findings indicate that EVTIA under LA is safe, with low conversion and mortality rates, even for ruptured aneurysms. Complications rates, also in IIHC rates, are comparable to those reported for GA, emphasizing LA's comparable safety profile in EVTIAs. Considering these promising outcomes, the decision to opt for the LA approach emerges as meaningful and well-suited for the endovascular treatment of aneurysms. Beyond its safety, LA introduces inherent supplementary advantages, including shortened hospitalization periods, cost-effectiveness, and an expedited patient recovery process.

Background: The decision to close patent ductus arteriosus should always be individualized and taken together with the child's family once the risks and benefits of both choices have been exposed. Objective: This study aims to report the experience and outcomes in patients undergoing endovascular closure of small to medium-size PDA with a Nit-Occlud® device in a tertiary referral hospital in Colombia. Methods: Longitudinal descriptive study, which included all patients under 18 years of age who underwent percutaneous ductal closure with Nit-Occlud® device between January 1, 2011, and February 1, 2023. Patients with associated complex congenital heart disease requiring surgical management, pregnant patients, and patients with incomplete data regarding studied variables were excluded from the study. Results: Eighty-seven patients were documented, with a mean age, weight, and height at closure of 51 months, 14 kg, and 95.83 cm, respectively. About 70% of the patients (n = 61) were female, 76% were under 6-years-old and only one patient was over 15. The average size of the ductus at the pulmonary end was 2 mm. Four of the total number of patients did not achieve PDA closure during the procedure. Of the remaining 83, complete immediate closure was achieved in 81 patients. A device exchange for a larger device was required during the same procedure in one of the cases. Two patients presented residual shunt of 0.5 mm during follow-up, and one required a new procedure for device closure 10 months later. Only one device presented repeatedly embolization to the aorta, requiring surgical removal. As a technical difficulty, one device presented repeated passage into the aorta, so it was decided to remove it before releasing it to avoid complications, and given the complex anatomy of the ductus, surgical closure was indicated. Among the complications, one patient presented a hematoma of the subcutaneous tissue in the right thigh, which improved with medical management, and no deaths related to the procedure were registered. Conclusions: Using the Nit-Occlud® device to close small to moderate-sized ductus remains a safe and effective strategy with successful closure rates at 1-year follow-up irrespective of age, weight, height, or whether it involves a small or medium-sized duct. Despite our limitations, results concerning adverse effects are comparable to those observed in multicentric studies conducted in other regions.
Antecdentes: La decisión de cerrar el conducto arterioso permeable (CAP) siempre debe ser individualizada y tomada en conjunto con la familia del niño una vez expuestos los riesgos y beneficios de ambas opciones. Objetivo: Este estudio tiene como objetivo informar la experiencia y los resultados en pacientes sometidos a cierre endovascular del CAP de tamaño pequeño a mediano con un dispositivo Nit-Occlud® en un hospital de tercer nivel de referencia en Colombia. Método: Estudio descriptivo longitudinal, que incluyó a todos los pacientes menores de 18 años a quienes se les realizó cierre ductal percutáneo con dispositivo Nit-Occlud® entre el 1 de enero de 2011 y el 1 de febrero de 2023. Se excluyeron: pacientes con cardiopatía congénita compleja asociada que requirieron manejo quirúrgico, pacientes embarazadas y pacientes con datos incompletos sobre las variables estudiadas. Resultados: Se documentaron 87 pacientes, con edad, peso y talla promedio al cierre de 51 meses, 14 kg y 95.83 cm, respectivamente. El 70% de los pacientes (n = 61) eran mujeres, el 76% tenían menos de seis años y solo un paciente tenía más de 15 años. El tamaño medio del conducto en el extremo pulmonar fue de 2 mm. Cuatro del total de pacientes no lograron el cierre del CAP durante el procedimiento. De los 83 restantes, se logró el cierre inmediato completo en 81 pacientes. En uno de los casos fue necesario cambiar el dispositivo por uno más grande durante el mismo procedimiento. Dos pacientes presentaron shunt residual de 0.5 mm durante el seguimiento y uno requirió un nuevo procedimiento para cierre del dispositivo diez meses después. Solo un dispositivo presentó embolización repetida en la aorta, requiriendo extracción quirúrgica. Como dificultad técnica, un dispositivo presentó paso repetido hacia la aorta, por lo que se decidió retirarlo antes de liberarlo para evitar complicaciones y dada la compleja anatomía del ductus se indicó cierre quirúrgico. Entre las complicaciones, un paciente presentó un hematoma del tejido subcutáneo en el muslo derecho, que mejoró con el manejo médico, y no se registraron muertes relacionadas con el procedimiento. Conclusiones: El uso del dispositivo Nit-Occlud® para cerrar conductos de tamaño pequeño a moderado sigue siendo una estrategia segura y eficaz con tasas de cierre exitoso al año de seguimiento, independientemente de la edad, el peso, la altura o si se trata de un conducto de tamaño pequeño o mediano. A pesar de nuestras limitaciones, los resultados sobre los efectos adversos son comparables a los observados en estudios multicéntricos realizados en otras regiones.

BACKGROUND: The Woven EndoBridge (WEB) device is a minimally invasive endovascular treatment option for patients with cerebral aneurysms. Transradial access (TRA) is a technique that involves accessing the arterial system through the radial artery in the wrist rather than the femoral artery in the groin. Several studies have investigated the use of TRA for WEB device deployment in treating intracranial aneurysms. METHODS: A systematic review was conducted to evaluate the TRA for WEB device deployment in treating intracranial aneurysms. The databases PubMed, Cochrane, Embase, Scopus, and Web of Science were searched. To reduce the risk of bias, this systematic review only included studies reporting on using TRA in WEB device deployment for intracranial aneurysm treatment with a minimum of four patients. RESULTS: In this systematic review, 186 patients were included across five studies, with TRA used in 183 cases analyzed. The study population had a higher proportion of females (n = 118%-69%) than males, with a mean age of 62 years old. Among the aneurysms treated, 46 were ruptured, and 119 were located at bifurcation sites, with a mean maximum diameter/width of 6.6 mm and mean height of 5.9 mm. Adjunctive coiling was used in three cases, and adjunctive stenting was used in nine cases. In two cases, conversion to a femoral artery access was necessary. CONCLUSION: The available results suggest TRA with the WEB device is a safe and effective alternative. However, using TRA versus TFA should be individualized based on patient factors and operator experience.

AIM: This study aimed to identify and map the production of knowledge on non-pharmacological strategies to reduce stress and anxiety in patients undergoing endovascular procedures. DESIGN: Scoping review. METHODS: The review was performed using the PRISMA-ScR guidelines. The searches were conducted in Scopus, PubMed, Web of Science, Wiley Online Library, BVS/BIREME, Lilacs, Gale Academic OneFile, SciELO, Cochrane Library, CAPES Catalog of Dissertations and Theses, Oswaldo Cruz Foundation Portal of Theses and Dissertations, and Theses and Dissertations from Latin America. RESULTS: Twenty-two articles were selected. The articles were published from 2001 to 2022, mostly in Iran, and there was a predominance of randomized clinical trials. The Spielberger State-Trait Anxiety Inventory was the most used instrument. The findings indicated that music therapy, educational guidelines or videos on the procedure, massage, psychological preparation and aromatherapy were the main non-pharmacological therapies used to reduce anxiety and stress in patients undergoing vascular procedures.

BACKGROUND: Aneurysms and diverticula of the left ventricle are rare entities in childhood, with a prevalence of less than 0.1%. Described since 1886, as a severe and potentially fatal disease if not corrected, mainly due to the presence of associated anomalies and the risk of rupture. OBJETIVE: Present other management options for ventricular diverticula, different from surgical options, using alternative materials that are not used very often in daily practice. METHOD: A detailed description of a case successfully managed with these new treatment modalities. RESULTS: Endovascular management of the left ventricular diverticulum, diagnosed prenatally in the patient presented, was successful after initial failure with surgical management. CONCLUSIONS: Endovascular management of ventricular diverticula, using alternative materials to those commonly used, is an attractive option with satisfactory results in these patients.

Over the last decades, minimally invasive techniques have revolutionized the endovascular treatment (EVT) of brain aneurysms. In parallel, the development of conscious sedation (CS), a potentially less harmful anesthetic protocol than general anesthesia (GA), has led to the course optimization of surgeries, patient outcomes, and healthcare costs. Nevertheless, the feasibility and safety of EVT of brain aneurysms under CS have yet to be assessed thoroughly. Herein, we systematically reviewed the medical literature about this procedure. In accordance with the PRISMA guidelines, four databases (PubMed, EMBASE, SCOPUS, and Cochrane Library) were queried to identify articles describing the EVT of brain aneurysms under CS. Successful procedural completion, complete aneurysm occlusion outcomes, intraoperative complications, clinical outcomes, and mortality rates assessed the feasibility and safety. Our search strategy yielded 567 records, of which 11 articles were included in the qualitative synthesis. These studies entailed a total of 1142 patients (40.7% females), 1183 intracranial aneurysms (78.4% in the anterior circulation and 60.9% unruptured at presentation), and 1391 endovascular procedures (91.9% performed under CS). EVT modalities under CS included coiling alone (63.2%), flow diversion (17.7%), stent-assisted coiling (10.6%), stenting alone (6.5%), onyx embolization alone (1.7%), onyx + stenting (0.2%), and onyx + coiling (0.2%). CS was achieved by combining two or more anesthetics, such as midazolam, fentanyl, and remifentanil. Selection criteria for CS were heterogenous and included patients' history of pulmonary and cardiovascular diseases, outweighing the benefits of CS versus GA, a Hunt and Hess score of I-II, a median score of 3 in the American Society of Anesthesiology scale, and patient's compliance with elective CS. Procedures were deemed successful or achieving complete aneurysm occlusion in 88.1% and 9.4% of reported cases, respectively. Good clinical outcomes were described in 90.4% of patients with available data at follow-up (mean time: 10.7 months). The procedural complication rate was 16%, and the mortality rate was 2.8%. No complications or mortality were explicitly attributed to CS. On the other hand, procedure abortion and conversion from CS to GA were deemed necessary in 5% and 1% of cases, respectively. The present study highlights the feasibility of performing EVT of brain aneurysms under CS as an alternative anesthetic protocol to GA. However, the limited nature of observational studies, methodological quality, the predominant absence of a comparative GA group, and clinical data during follow-up restrict a conclusive statement about the safety of EVT under CS. Accordingly, further research endeavors are warranted toward a higher level of evidence that can be translated into surgical practice.

BACKGROUND: Cerebral Venous Sinus Thrombosis (CVST) is a rare but potentially life-threatening condition, often associated with specific risk factors. The primary treatment for CVST is anticoagulation, but some cases progress to Refractory CVST (rCVST), requiring endovascular treatment. A combination of stent retriever and catheter aspiration is emerging as a promising technique to enhance treatment effectiveness. We conducted a systematic review and meta-analysis to assess the safety and efficacy of this approach, aiming to improve recanalization success and neurological outcomes while reducing complications in rCVST patients. METHODS: A search following PRISMA guidelines was conducted across Pubmed, Embase, Web of Science, and Cochrane databases to identify studies on the use of stent retrievers and catheter aspiration for rCVST. Pooled analysis with 95 % confidence intervals was used to assess the effects. Heterogeneity was evaluated using I2 statistics and a random-effects model was used. Complete recanalization. good clinical outcomes (mRS ≤ 2), hemorrhagic, neurological, ischemic, and total complications, poor clinical outcomes (mRS > 2), and mortality were assessed. RESULTS: A meta-analysis of five retrospective studies involving 55 patients examined outcomes in CVST. The median mean age was 40 years. Complete recanalization rate: 36 % (95 % CI: 9 % to 62 %, I2 = 90 %). Good clinical outcomes: 72 % (95 % CI: 50 % to 94 %, I2 = 76 %). Hemorrhagic complications: 2 % (95 % CI: 0 % to 8 %, I2 = 15 %). Ischemic complications: 0 % (95 % CI: 0 % to 6 %, I2 = 0 %). Neurological complications: 7 % (95 % CI: 0 % to 14 %, I2 = 0 %). Poor clinical outcomes: 26 % (95 % CI: 6 % to 46 %, I2 = 70 %). Total complications: 6 % (95 % CI: 0 % to 15 %, I2 = 10 %). Mortality rate: 5 % (95 % CI: 0 % to 13 %, I2 = 19 %). CONCLUSION: This systematic review and meta-analysis scrutinized the efficacy of combining Stent Retriever and Catheter Aspiration for rCVST. Findings highlighted varied outcomes, including recanalization rates, complications, and mortality. The dichotomy between good and poor outcomes underscores the necessity for personalized therapeutic decisions. While offering a comprehensive overview, the study emphasizes literature heterogeneity, suggesting a need for more rigorous and standardized research to optimize therapeutic strategies in clinical practice.

PURPOSE: We report the case of an acute type B dissection with high-risk features treated with multilayer stent. CASE REPORT: A 50-year-old female patient presented to the emergency department with an acute type B aortic dissection. Conservative medical treatment did control blood pressure but did not alleviate her dissection symptoms. She was treated endovascularly with multilayer stents extensively covering the whole dissected area. HThe aortic arch side branches, visceral arteries and renal arteries remained patent after treatment. The recovery was uneventful, and she was discharged the day after the intervention. At 6- and 12-month follow-up, the patient remained asymptomatic, the true lumen volume increased and all side branches remained patent. CONCLUSION: We present a case of the use of a multilayer stent for acute type B aortic dissection. This technique allows to treat the whole dissection with low risk of paraplegia or side branch occlusion. Long-term results of ongoing clinical studies should confirm the place of the multilayer stent as a treatment option for type B aortic dissection.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is gaining popularity worldwide for managing hypotensive trauma patients. Vascular access complications related to REBOA placement have been reported, with some cases resulting in permanent morbidity. We aim to capitalize on the increase in literature to further describe and estimate the incidence of REBOA-associated vascular access complications in adult trauma patients. METHODS: We searched Medline, EMBASE, Scopus, and CINAHL for studies reporting vascular access complications of REBOA in adult trauma patients from inception to October 14, 2021. Studies reporting data from adult trauma patients who underwent REBOA insertion were eligible. Exclusion criteria included patients 15 years and younger, nontrauma patients, non-REBOA use, non-vascular access complications and patient duplication. Study data was abstracted using the PRISMA checklist and verified independently by three reviewers. Meta-analysis of proportions was performed using a random effects model with Freeman-Turkey double-arcsine transformation. Post hoc meta-regression by year of publication, sheath-size, and geographic region was also performed. The incidence of vascular access complications from REBOA insertion was the primary outcome of interest. Subgroup analysis was performed by degree of bias, sheath size, technique of vascular access, provider specialty, geographical region, and publication year. RESULTS: Twenty-four articles were included in the systematic review and the meta-analysis, for a total of 675 trauma patients who underwent REBOA insertion. The incidence of vascular access complications was 8% (95% confidence interval, 5%-13%). In post hoc meta-regression adjusting for year of publication and geographic region, the use of a smaller (7-Fr) sheath was associated with a decreased incidence of vascular access complications (odds ratio, 0.87; 95% confidence interval, 0.75-0.99; p = 0.046; R 2 = 35%; I 2 = 48%). CONCLUSION: This study provides a benchmark for quality of care in terms of vascular access complications related to REBOA insertion in adult trauma patients. Smaller sheath size may be associated with a decrease in vascular access complications. LEVEL OF EVIDENCE: Systematic Review and Meta-Analysis; Level III.

INTRODUCTION: Intracranial mycotic or infectious aneurysms result from the infection of arterial walls, most caused by bacterial or fungal organisms. These infections can weaken the arterial wall, leading to the formation of an aneurysm, a localized dilation, or a bulge. The management can be conservative mainly based on antibiotics or invasive methods such as clipping or endovascular treatment. PURPOSE: We performed a systematic review and meta-analysis of the current literature on endovascular treatment of mycotic aneurysms, analyzing the safety and efficacy associated with this procedure. METHODS: We systematically searched on PUBMED, Cochrane Library, Embase, and Web of Science databases. Our search strategy was carefully crafted to conduct a thorough investigation of the topic, utilizing a comprehensive combination of relevant keywords. This meta-analysis included all studies that reported endovascular treatment of mycotic aneurysms. To minimize the risk of bias, studies with fewer than four patients, studies where the main outcome was not found, and studies with no clear differentiation between microsurgical and endovascular treatment were excluded. RESULTS: In a comprehensive analysis of 134 patients, it was observed that all except one patient received antibiotics as part of their treatment. Among the patients, 56% (a total of 51 out of 90 patients) underwent cardiac surgery. Additionally, three patients required a craniotomy following endovascular treatment. 12 patients experienced morbidity related to the procedures performed, indicating complications arising from the interventions. Furthermore, four aneurysms experienced rebleeding while treatment. A pooled analysis of the endovascular treatment of the mycotic aneurysm revealed a good level of technical success, achieving a 100% success rate in 12 out of 14 studies (97-100%; CI 95%; I2 = 0%), as illustrated in Fig. 2. Similarly, the aneurysm occlusion rate demonstrated a notable efficacy, with a success rate of 97% observed in 12 out of 14 studies (97-100%; CI 95%; I2 = 0%), as depicted in Fig. 3. CONCLUSION: The results strongly support the efficacy of endovascular treatment in achieving technical success, complete aneurysm occlusion, and favorable neurological outcomes. Additionally, the notably low incidence of complications and procedure-related mortality reaffirms the safety and benefits associated with this intervention.
