RESUMEN
OBJECTIVES: Image-based sarcopenia has been the subject of recent studies, hypothesized as a prognostic factor for patients with thoracoabdominal aortic aneurysms. METHODS AND MATERIALS: We conducted a single-center retrospective analysis of patients who underwent complex endovascular repair for thoracoabdominal aortic aneurysms between 2008 and 2016. CT image assessment was performed and patients were classified as sarcopenic and non-sarcopenic using two stratification methods: skeletal mass index (SMI) and total psoas muscle index (TPMI). According to sex, each patient was defined as sarcopenic if their SMI or TPMI was in the lowest third of the study group. The primary endpoint was impact of sarcopenia on perioperative mortality and long-term survival. Secondary endpoints were perioperative complications. RESULTS: From a total of 155 patients, 135 were eligible for study. Overall, in-hospital mortality was 5.9% (8/135). The 30-day, 1-year, 3-year and 5-year mortality was 10.4% (14/135), 20% (27/135), 28.1% (38/135) and 31.1% (42/135), respectively. There was no difference in the long-term mortality rates between sarcopenic and non-sarcopenic patients regardless of the stratification method used (p = 0.4 for SMI and p = 0.2 for TPMI). According to SMI, 30-day mortality of sarcopenic patients was significantly lower in comparison to non-sarcopenic patients (1/45, 2.2% vs. 13/90, 14.4%, p = 0.028). Based on the total psoas muscle index, sarcopenic patients were at higher risk for development of pulmonary complications in comparison to non-sarcopenic patients postoperatively (p = 0.03). CONCLUSION: Using SMI and TPMI, sarcopenia was not associated with reduced long-term survival in patients undergoing complex endovascular repair for thoracoabdominal aortic aneurysms.
RESUMEN
BACKGROUND: The popliteal artery is highly exposed to biomechanical stress, which is the primary factor associated with stent failure. However, information on the optimal endovascular treatment for the popliteal artery is lacking. OBJECTIVE: To report the efficacy of the GORE® TIGRIS® Vascular Stent for the endovascular treatment of popliteal artery lesions. METHODS: Retrospective analysis of all patients with symptoms of peripheral artery occlusive disease (PAD) and popliteal artery lesions who underwent implantation of a GORE® TIGRIS® Vascular Stent between August 2012 and August 2014 at a tertiary vascular centre. RESULTS: Between August 2012 and August 2014, 48 patients (32 men, aged 75±8 years) were treated with a GORE® TIGRIS® Vascular Stent. The technical success rate was 100%. At 12 months, the primary and secondary patency rates were 74% and 85%, respectively. During follow-up, no stent fracture was observed. No major amputations were performed. CONCLUSIONS: Our study showed that isolated popliteal artery lesions in patients with symptomatic PAD could easily be treated with the GORE® TIGRIS® Vascular Stent, as good short-term results were achieved at 12 months. Therefore, the discontinuation of this product removed a useful tool with a simple release mechanism from the endovascular armamentarium of vascular specialists.

BACKGROUND: Prophylactic mesh implantation following open surgical repair of abdominal aortic aneurysm is a debatable subject. OBJECTIVE: To assess the efficacy of a self-gripping polyester mesh used in on-lay technique to prevent incisional hernia after open abdominal aortic aneurysm repair. METHODS: We retrospectively reviewed the records of 495 patients who underwent aortic surgery between May 2017 and May 2021. Patients included in the study underwent open surgical repair for infrarenal abdominal aortic aneurysm (AAA) with closure of the abdominal wall with either small bite suture technique or prophylactic mesh reinforcement. Primary endpoint of the study was the occurrence of incisional hernia during a two-year follow-up period. Secondary endpoints were mesh-related complications. RESULTS: Mesh implantation with the on-lay technique was successful in all cases. No patient in the mesh group developed an incisional hernia during the 24-month follow-up period. Two patients in the non-mesh group developed a symptomatic incisional hernia during the follow-up period at 6 months. Three cases of post-operative access site complications were observed in the mesh group. CONCLUSIONS: Application of a self-gripping polyester mesh using the on-lay technique demonstrates acceptable early-durability after open surgical repair of abdominal aortic aneurysms. However, it appears to be associated with a number of post-operative access site complications.

There are many publications dealing with treatment options for uncomplicated type B aortic dissection (TBAD). Early TEVAR (Thoracic Endovascular Aortic Repair) may improve aortic-specific survival and delay disease progression in the long-term. Especially in patients with uncomplicated TBAD and additional high-risk features, preemptive TEVAR may improve late outcomes.We conducted a retrospective analysis of all patients treated for TBAD in our hospital between February 2017 and September 2021. Comorbidities, intraoperative data, 30-day mortality and postprocedural complications were analysed.During the above-mentioned period, 61 patients (38 males, median age 63 years) with TBAD were treated. Six patients received best medical treatment (BMT). 55 patients were treated by TEVAR and BMT. 11 patients (20%) had complicated TBAD, 12 patients (22%) had uncomplicated TBAD with high-risk features and 32 patients (58%) had uncomplicated TBAD. Technical success was 100%. No patient with uncomplicated TBAD died within the first 30 postoperative days. One patient with uncomplicated TBAD had a stroke after TEVAR. Two reinterventions were performed on day 7 and day 9 after TEVAR.Patients with uncomplicated TBAD could be treated by early TEVAR, with a low rate of perioperative complications. In patients with uncomplicated TEVAR and high-risk features, early TEVAR with BMT should be considered as the treatment of choice.
RESUMEN
BACKGROUND: The acute occlusion of a peripheral bypass graft leads to acute limb ischemia (ALI) and threatens the viability of the limb if left untreated. The aim of the present study was to analyze the results of surgical and hybrid revascularization techniques for patients with ALI due to peripheral graft occlusions. METHODS: A retrospective analysis of 102 patients undergoing treatment for ALI due to peripheral graft occlusion between 2002 and 2021 was carried out at a tertiary vascular center. Procedures were classified as surgical when only surgical techniques were used and as hybrid when surgical procedures were combined with endovascular techniques such as balloon or stent angioplasty or thrombolysis. Endpoints were primary and secondary patency and amputation-free survival after 1 and 3 years. RESULTS: Of all patients, 67 met the inclusion criteria, 41 were treated surgically and 26 by hybrid procedures. There were no significant differences in the 30-day patency rate, 30-day amputation rate, and 30-day mortality. The 1- and 3-year primary patency rates were 41.4% and 29.2% overall, respectively; 45% and 32.1% in the surgical group, respectively; and 33.2% and 26.6% in the hybrid group, respectively. The 1- and 3-year secondary patency rates were 54.1% and 35.8% overall, respectively; 52.5% and 34.2% in the surgical group, respectively; and 54.4% and 43.5% in the hybrid group, respectively. The 1- and 3-year amputation-free survival rates were 67.5% and 59.2%, overall, respectively; 67.3% and 67.3% in the surgical group, respectively; and 68.5% and 48.2% in the hybrid group, respectively. There were no significant differences between the surgical and the hybrid groups. CONCLUSIONS: The results of surgical and hybrid procedures after bypass thrombectomy for ALI to eliminate the cause of infrainguinal bypass occlusion are comparable with good midterm results in terms of amputation-free survival. New endovascular techniques and devices need to be established in comparison to the results of these proven surgical revascularization methods.

BACKGROUND: The purpose of this study is to assess the efficacy of a suture-mediated closure device during percutaneous endovascular aortic repair. METHODS: A single-center, retrospective analysis of patients undergoing endovascular repair for infrarenal, thoracic and thoracoabdominal aortic aneurysms and aortic dissections via percutaneous femoral access between April 2017 and June 2021 was performed. The primary endpoint of the study was the efficacy and technical success of the Perclose ProGlide closure device during percutaneous endovascular procedures. The secondary endpoints were intraoperative and postoperative inguinal and vascular complications during and after device use. RESULTS: A total of 376 punctures were performed in 263 patients with the deployment of the ProGlide vascular closure system. Twenty-two cases involved percutaneous re-puncture as part of a staged procedure. The primary and secondary technical success rates were 93.1% (350/376) and 94.7% (356/376), respectively. In 20 patients (5.3%), intraoperative femoral exposure due to complications was required. Postoperative complications occurred in 13 cases (3.5%), 2 of which required surgical reintervention. There was no statistical significance between the type of endovascular procedure and primary technical success (p = 0.56). The introduction of larger-diameter sheaths was not associated with increased intraoperative and postoperative complication rates (p = 0.75 and p = 0.78, respectively). Percutaneous re-puncture of the vascular access site did not result in a lower overall technical success rate (20/22, 90.9% primary technical success rate, p = 0.67; 21/22, 95.5% secondary technical success rate, p = 0.86) or an increased number of perioperative complications (1/22, 4.5% intraoperative complications, p = 0.86; 2/22, 9.1% postoperative complications, p = 0.13). CONCLUSION: The application of the ProGlide closure system is a safe and efficient method to achieve hemostasis during percutaneous endovascular aortic repair. Complex aortic pathologies, which often require a staged approach with re-puncture, can also be successfully treated with this closure system.
RESUMEN
OBJECTIVES: To present our experience with various therapeutic approaches for the treatment of secondary aortoenteric fistulas following open and endovascular aortic aneurysm repair. METHODS AND MATERIALS: A retrospective data analysis of patients treated for secondary aortoenteric fistulas in a single vascular institution between January 2005 and December 2018 was performed. Analyzed parameters included patients' demographics, clinical presentation, diagnostic work-up, perioperative data and repair durability during follow-up. RESULTS: Twenty-three patients with aortoenteric fistulas were treated in the target period. The fistulous connection was located in 21 cases (91.3%) in the duodenum and in two cases (8.7%) in the small intestine. Average time between the initial procedure and detection of the aortoenteric fistula was 69.4 ± 72.5 months. The most common presenting symptom was gastrointestinal bleeding (n = 12, 52.2%), followed by symptoms suggestive of chronic infection (n = 11, 47.8%). Open surgical repair was performed in 19 patients (bridging in 3 patients), and endovascular repair was carried out in two cases and one patient underwent a hybrid operation. One patient underwent abscess drainage due to significant comorbidities. Mean follow-up was 35.1 ± 35.5 months. In-hospital mortality and overall mortality were 43.5% (10/23) and 65.2% (15/23), respectively. Patients presenting with bleeding had a significantly higher perioperative mortality rate in comparison to patients presenting with chronic infection (66.7% (8/12) and 18.2% (2/11), respectively, p = 0.019). Patients who underwent stent-graft implantation for control of acute life-threatening bleeding showed significantly better perioperative survival in comparison to patients that were acutely treated with an open procedure (66.6%, (4/6) and 0% (0/6), respectively, p = 0.014). Perioperative mortality was also higher for ASA IV patients (71.4%, 5/7), when compared to ASA III Patients (31.2%, 5/16), although this did not reach statistical significance (p = 0.074). CONCLUSION: Treatment of secondary aortoenteric fistulas is associated with a high perioperative mortality rate. Patients who survive the perioperative period following open surgical repair in the absence of hemorrhagic shock show acceptable midterm results during follow-up. Stent-graft implantation for bleeding control in patients presenting with life-threatening bleeding seems to be associated with lower perioperative mortality rates.
RESUMEN
PURPOSE: Open surgical repair of type Ia endoleak after endovascular aortic aneurysm repair/sealing (EVAR/EVAS) is associated with significant perioperative mortality and morbidity. Current endovascular redo techniques face limitations, especially when the infrarenal landing zone is inadequate and the previous endograft is rigid and features a short or no main body. We present a novel concept for the treatment of type Ia endoleak using a custom-made branched device. TECHNIQUE: The 5-branch-device (Cook Medical, Bloomington, IN, USA) consists of a nitinol skeleton with branches, covered with a low-profile polyester fabric loaded in an 18F sheath. The device features a minimum of 2 proximal sealing stents and includes branches for renovisceral vessels as well as an additional 8 mm branch for the contralateral iliac limb. Implantation and sealing in the renovisceral vessels is carried out in standard fashion, using transfemoral and transaxillary access. Distal sealing is achieved by tapering the branched component into the ipsilateral iliac limb and using a bridging balloon-expandable or self-expandable stent-graft through the additional branch to the preexisting contralateral iliac limb. CONCLUSION: Treatment of type Ia endoleak with a new custom-made device enables sufficient proximal seal while minimizing suprarenal aortic coverage and facilitates adequate component overlap. The low profile branched design accommodates implantation through the preexisting endograft and catheterization of target vessels.

BACKGROUND: Arterioureteral fistula refers to the anomalous fistulous connection between the iliac artery and the ureter. It is often associated with pelvic malignancy, abdominal surgery, and radiation. As it is a potentially life-threatening condition, prompt diagnosis and management is essential. METHODS: We performed a retrospective analysis of patients treated for arterioureteral fistula in a single-vascular institution from January 2013 to March 2019. Preoperative assessment included physical and laboratory examinations and medical history, with diagnosis established through computed tomography angiography, digital subtraction angiography, or ureteroscopy. Parameters analyzed included perioperative mortality and morbidity as well as treatment durability during midterm follow-up. RESULTS: Nine patients with ten arterioureteral fistulas were included in the study. Macroscopic hematuria was the main presenting symptom, with 2 patients admitted due to hemorrhagic shock. Endovascular treatment was carried out in 6 patients. In 4 cases, single stent-graft deployment inside the common iliac artery was performed, in one case in combination with plugging of the internal iliac artery. One patient underwent implantation of an iliac-branched device, whereas in another patient coiling of the internal iliac artery sufficed for management of the fistula. Open surgical repair was carried out in three cases. Perioperative mortality was zero; one patient had prolonged hospital stay due to superficial wound infection. Recurrent hematuria and stent-graft infection were observed during follow-up in three patients after endovascular repair, all of them treated through open surgery with no further complications. One patient developed an enterocutaneous fistula after open repair during follow-up and required redo surgery. DISCUSSION: Arterioureteral fistula is a challenging clinical scenario demanding prompt diagnosis and management. Open surgery remains the treatment of choice in cases of preexisting vascular reconstruction or manifest infection. Endovascular techniques offer a viable solution in significantly comorbid patients or in patients presenting with acute, life-threatening bleeding. Rigorous follow-up is required regardless of treatment modality due to the considerable rate of reinterventions.

BACKGROUND: Horseshoe kidney (HSK), referring to the abnormal fusion of the lower renal poles, represents one of the most common renal anomalies. One of its most significant features is the anomalous vasculature, with a number of accessory renal arteries originating from the aorta, the mesenteric arteries, and even the iliac arteries supplying both the renal kidneys and the renal isthmus. METHODS: A literature review was performed to identify and to present the most recent data regarding classification and imaging evaluation of HSK concomitant with abdominal aortic aneurysm (AAA). Furthermore, an in-depth analysis of both open surgical and endovascular repair is made for management of this rare medical condition. RESULTS: The anomalous renal vasculature of HSK has led to the introduction of a number of classification systems, with Eisendrath's being currently the most commonly used. The concomitant presence of HSK in patients suffering from AAA plays a major role in preoperative planning, with a number of factors taken into consideration in deciding on either an open repair or an endovascular approach. Open repair requires careful decision-making between a transperitoneal and a left retroperitoneal approach to reach the aneurysm sac. In addition, technical points include the decision to divide the renal isthmus or not and the necessity of salvage or reimplantation of anomalous renal vessels. On the other hand, an endovascular approach requires careful preoperative imaging and evaluation of both the renal function and vasculature to decide on catheterization and salvage of accessory renal arteries or their exclusion. CONCLUSIONS: The concomitant presence of AAA and HSK poses a challenge for the modern vascular surgeon, who must possess all required technical skills-both endovascular and open repair-to deal accordingly with this rarely encountered medical condition. Preoperative determination of the perfusion pattern is necessary for the treatment strategy.

BACKGROUND: This meta-analysis aimed to evaluate randomized trials (RTs) that compare outcomes among asymptomatic patients with significant carotid stenosis undergoing carotid endarterectomy (CEA) versus carotid stenting (CAS) or best medical treatment (BMT). MATERIAL AND METHODS: The Pubmed, Embase, Scopus and Cochrane Library databases were systematically searched to identify eligible studies. Data were analyzed by using the StatsDirect Statistical software (Version 2.8.0, StatsDirect Ltd). Odds ratios (OR) were used to determine effect size, along with 95% confidence interval (CI). PRISMA guidelines for conducting meta-analyses were utilized. RESULTS: Overall, 10 RTs including 8771 asymptomatic patients were evaluated. Compared to CAS, 30-day all stroke risk was found to be lower after CEA (pooled ORâ¯=â¯0.56; CI 95% [0.312-0.989]; Pâ¯=â¯0.046). However, other early and late outcomes were not different between CEA and CAS. Furthermore, 30-day all stroke (pooled ORâ¯=â¯3.43; CI 95% [1.810-6.510]; Pâ¯=â¯0.0002), death (pooled ORâ¯=â¯4.75; CI 95% [1.548-14.581]; Pâ¯=â¯0.007) and myocardial infarction (MI) (pooled ORâ¯=â¯9.18; CI 95% [1.668-50.524]; Pâ¯=â¯0.011) risks were higher after CEA compared to BMT, as expected. Additionally, 30-day all stroke/death and all stroke/death/MI risks were higher after CEA compared to BMT as well. Regarding long-term results, ipsilateral stroke risk was lower after CEA compared to BMT (pooled ORâ¯=â¯0.46; CI 95% [0.361-0.596]; Pâ¯<â¯0.0001) although death due to stroke risk was not different (pooled ORâ¯=â¯0.57; CI 95% [0.223-1.457]; Pâ¯=â¯0.240). Unfortunately, no study comparing CAS to BMT was found. CONCLUSIONS: CEA is associated with a lower early all stroke risk compared to CAS although other early or late outcomes did not show any difference between the two methods. Additionally, CEA seems to have a benefit over BMT against long-term ipsilateral stroke, although early outcomes are worse after CEA. No studies are available comparing CAS to BMT alone.

The incidence of combined neurovascular injuries among patients with high-energy shoulder trauma ranges from 27% to 44%. However, the presentation of an axillary artery pseudoaneurysm (PSA) due to shoulder dislocation without an associated osseous fracture is a very rare condition. Moreover, treatment of combined neurologic and vascular injuries of the shoulder remains controversial. Additionally, minimally invasive treatments such as thrombin injection have been mainly evaluated in patients with iatrogenic femoral artery PSAs. Therefore, we aim to report a rare case of axillary artery PSA associated with brachial plexus injury after shoulder dislocation treated with percutaneous thrombin injection.
