RESUMEN

BACKGROUND: Bronchial stenosis associated with bronchial anastomosis dehiscence after lung transplantation is a catastrophic complication following lung transplantation with a paucity of therapeutic solutions. PURPOSE: To describe an adaptation of the parallel stent grafting technique in the pulmonary arterial territory to treat this challenging situation. RESEARCH DESIGN: This is a case report of a 52-year-old patient who presented bronchus stenosis and bronchial anastomosis dehiscence after lung transplantion. Bronchial stenting and lung retransplantation were contraindicated. Therefore, an endovascular approach using pulmonary artery endograft placement to prevent bleeding during repeated right bronchial balloon dilation was propposed. The technique consists of the deployment of an aortic extender endoprosthesis in the right main pulmonary artery and a balloon expandable stent in the upper lobe pulmonary artery (using a parallel graft configuration) through the common femoral and right internal jugular veins, respectively. Intraoperative transesophageal echocardiogram and one-lung ventilatory ventilation are needed. RESULTS: The patient underwent a new bronchoscopy 16 days after the procedure, that showed epithelization at the previous eroded zone, enabling bronchocopic balloon dialtion to be safely performed. A post-operative contrast-enhanced CT scan revealed an adequate positioning of the stent grafts. Despite all eforts, the patient succumbed to ventilator associated pneumonia on postoperative day 108. DATA ANALYSIS: The technique's advantages include its feasibility even in situations in which other techniques may be contraindicated and its potential use in emergencies. Its limitations include the need for experienced interventionists to perform it, and the potential risk of acute tricuspid regurgitation. CONCLUSION: This study illustrates the early feasibility of the parallel stent grafting technique applied to the pulmonary artery territory. However, it's safety profile regarding infectious risk was not demontrated.

RESUMEN

OBJECTIVE: To investigate clinical effects of hepatic artery interventional embolization chemotherapy (TACE) for primary hepatocellular carcinoma (PHC). METHODS: 73 patients with PHC in our hospital from January 2017 to January 2018 were selected and divided into 37 cases in study group and 36 cases in control group by random number table method. The control group received only ultrasound-guided microwave ablation treatment, and the study group received TACE treatment again before surgery based on control group. The expression levels of cancer antigen 125 (CA125), alpha-fetoprotein (AFP), multiple tumor suppressors 1 (P16) proteins, and cancer antigen 19-9 (CA19-9) were compared between the two groups at different time periods after treatment, and the remission rate (ORR), control rate (DCR), complication rate at 3 months after treatment and survival rate at 3 years after treatment were compared. RESULTS: After 1 year of treatment, ORR, DCR, and P16 protein levels in the study group were higher than those in the control group (P < 0.05), and differences were statistically significant; CA125, CA19-9, and AFP levels in study group were lower than those in the control group (P < 0.05), and differences were statistically significant. The regression equation showed that long-term survival rate of both groups showed decreasing trend over time, while long-term survival rate of study group was always higher than that of the control group. CONCLUSION: Comprehensive intervention for hepatic artery interventional chemoembolization in patients with primary hepatocellular carcinoma is more effective, which can effectively reduce incidence of complications and adverse effects in patients and help shorten treatment time of hepatic artery interventional chemoembolization in patients.

RESUMEN

OBJECTIVES: To study the complications and effectiveness of the treatment of chronic arrhythmias with cardiac Ganglion Plexus (GP) ablation, and to explore the value of the treatment of chronic arrhythmias with GP ablation. METHODS: This study was a one-arm interventional study of patients from the first hospital of Xinjiang Medical University and the People's Hospital of Xuancheng City admitted (09/2018-08/2021) because of bradyarrhythmia. The left atrium was modeled using the Carto3 mapping system. The ablation endpoint was the absence of a vagal response under anatomically localized and high-frequency stimulation guidance. Postoperative routine follow-up was conducted. Holter data at 3-, 6-, and 12-months were recorded. RESULTS: Fifty patients (25 male, mean age 33.16 ± 7.89 years) were induced vagal response by either LSGP, LIGP, RAGP, or RIGP. The heart rate was stable at 76 bpm, SNRT 1.092s. DC, DR, HR, SDNN, RMSSD values were lower than that before ablation. AC, SSR, TH values were higher than those before ablation, mean heart rate and the slowest heart rate were significantly increased. There were significant differences in follow-up data between the preoperative and postoperative periods (all p < 0.05). All the patients were successfully ablated, and their blood pressure decreased significantly. No complications such as vascular damage, vascular embolism and pericardial effusion occurred. CONCLUSIONS: Left Atrial GP ablation has good long-term clinical results and can be used as a treatment option for patients with bradyarrhythmia.

RESUMEN

OBJECTIVE: To compare the short and long-term benefits (the length of hospital stay, surgical complications, and early clinical improvement) of adding early ultrasound-guided drainage to broad-spectrum antibiotic treatment. METHODOLOGY: Patients undergoing tubo-ovarian abscess treatment between January 2017 and June 2022 in a tertiary hospital were retrospectively evaluated. Of the patients studied, 50 subjects were treated with antibiotics alone and 63 underwent guided drainage. Twenty-one individuals underwent early drainage within 72 hours of admission, and 42 underwent guided drainage after this period. RESULTS: There was no statistical difference in the length of hospital stay between the groups simultaneously, averaging 6.4 days for the controls, 5.1 days for the early drainage group, and 9.6 days for the late drainage group (p = 0.290). In the multiple linear regression with the length of hospital stay outcome and adjusting for potential confounding factors, there was an average reduction of 2.9 days in the hospital stay (p = 0.04) for the early drainage group (< 72 hours) compared to the controls. Early clinical improvement and an expected drop in CRP were more frequent in patients who underwent drainage. Length of hospital stay increases with abscess diameter: 0.4 [(95% CI 0.1 - 0.7) (p = 0.05)] days per centimeter, regardless of other variables. CONCLUSIONS: Ultrasound-guided drainage of tubo-ovarian abscesses associated with antibiotic therapy is an effective treatment, with few complications, and may lead to clinical improvement especially when performed early.

RESUMEN

Background.Anecdotal reports are appearing in the scientific literature about cases of brain tumors in interventional physicians who are exposed to ionizing radiation. In response to this alarm, several designs of leaded caps have been made commercially available. However, the results reported on their efficacy are discordant.Objective.To synthesize, by means of a systematic review of the literature, the capacity of decreasing radiation levels conferred by radiation attenuating devices (RADs) at the cerebral level of interventional physicians.Methodology.A systematic review was performed including the following databases: MEDLINE, SCOPUS, EBSCO, Science Direct, Cochrane Controlled Trials Register (CENTRAL), WOS, WHO International Clinical Trials Register, Scielo and Google Scholar, considering original studies that evaluated the efficacy of RAD in experimental or clinical contexts from January 1990 to May 2023. Data selection and extraction were performed in triplicate, with a fourth author resolving discrepancies.Results.Twenty articles were included in the review from a total of 373 studies initially selected from the databases. From these, twelve studies were performed under clinical conditions encompassing 3801 fluoroscopically guided procedures, ten studies were performed under experimental conditions with phantoms, with a total of 88 procedures, four studies were performed using numerical calculations with a total of 63 procedures. The attenuation and effectiveness of provided by the caps analyzed in the present review varying from 12.3% to 99.9%, and 4.9% to 91% respectively.Conclusion.RAD were found to potentially provide radiation protection, but a high heterogeneity in the shielding afforded was found. This indicates the need for local assessment of cap efficiency according to the practice.

RESUMEN

Introduction: Osteoid osteoma is a benign bone tumor that accounts for roughly 2-3% of primary bone tumors and up to 10-12% of benigns bone neoplasms. It is most commonly seen in young adults, and shows male predominance. Over the last years, minimally invasive thermal ablation techniques such as radiofrequency ablation have gained popularity over classical surgery. In this study we evaluate results and complications of CT guided osteoid osteoma radiofrequency ablation. Materials and methods: In this retrospective cohort study all patients that were diagnosed with osteoid osteoma and treated using radiofrequency ablation between January 2014 and December 2022 were included. Pain was assessed using Visual Analog Scale (VAS) pre and post procedure. Technical success was established as positioning of the radiofrequency electrode in the nidus. Primary clinical success was defined as absence of pain after one radiofrequency session. All patients that required a second radiofrequency ablation were included in the overall clinical success group. Results: During the studied period, 61 osteoid osteoma radiofrequency ablations were performed. Fiftyseven of them were included in this study, 32 were men and 25 female. Pre procedure median pain was 9 according to VAS score. Only 23 patients were treated as outpatient, the rest stayed in hospital for 24 hours. Median follow up time was 21,7 months (SD 8,3). Biopsy was performed in 52 patients. Technical success was accomplished in 57 patients (100%). Primary clinical success was 80,7% (46 patients). Those who continued with pain or had recurrence after a symptoms free period (11 patients), were treated with a second radiofrequency ablation, achieving an overall success rate of 94,7%. Only one patient suffered a minor complication (1,7%). Conclusion: CT guided osteoid osteoma radiofrequency ablation is a safe, effective and low complication rate procedure, that can be performed on an outpatient basis. We believe it should be considered as a first line treatment option for osteoid osteoma.

Introducción: El osteoma osteoide es un tumor óseo benigno, que representa el 2-3% de las neoplasias óseas primarias y hasta el 10-12% de los tumores óseos benignos. Tiene mayor incidencia en adultos jóvenes, con predominancia masculina. En los últimos años las técnicas de termoablación mínimamente invasivas han sido utilizadas para el tratamiento del osteoma osteoide, como alternativa a la cirugía clásica. En este estudio evaluaremos los resultados y complicaciones de ablación por radiofrecuencia de osteoma osteoide. Materiales y métodos: Se analizó una cohorte de pacientes en forma retrospectiva con diagnóstico de osteoma osteoide tratados con radiofrecuencia en el Hospital Italiano de Buenos Aires desde Enero del año 2014 hasta Diciembre del año 2022. Todos los pacientes fueron evaluados con la Escala Visual Analógica del dolor (EVA) pre y post procedimiento. El éxito técnico del procedimiento fue considerado como el correcto posicionamiento del electrodo de radiofrecuencia en el nido de la lesión, y el éxito clínico primario como ausencia de dolor post procedimiento. Mientras que los pacientes que requirieron de una segunda sesión de radiofrecuencia para controlar los síntomas serán incluidos como éxito clínico secundario. Resultados: Durante el período mencionado se realizaron 61 ablaciones percutáneas de osteoma osteoide. Se incluyeron en el análisis 57 pacientes, 32 fueron hombres y 25 mujeres. La media de dolor medido por EVA pre procedimiento fue 9. Del total de los pacientes, 23 fueron tratados de manera ambulatoria, el resto permanecieron internados durante 24hs. El tiempo medio de seguimiento fue de 21,7 meses (DS8,3). Se realizó biopsia de la lesión durante el procedimiento en 52 pacientes. Se logró el éxito técnico en 57 pacientes (100%), de ellos el éxito clínico primario se logró en 46 pacientes (80,7%). Los 11 pacientes que continuaron con dolor o presentaron recurrencia de los síntomas luego de un período asintomáticos fueron tratados con una segunda sesión de radiofrecuencia, logrando un éxito clínico secundario 94,7%. Un solo paciente presentó complicaciones post procedimiento (1,7%), correspondiente a hematoma en la planta del pie. Conclusión: Podemos concluir que la ablación percutánea por radiofrecuencia de OO guiada por tomografía en manos de expertos, es un procedimiento seguro, de alta efectividad y baja tasa de complicaciones que puede realizarse de manera ambulatoria. Por lo que consideramos que debe ser tenida en cuenta como primera elección para el tratamiento de esta patología.

RESUMEN

Cervical cancer (CC) occupies the second place in incidence and mortality among women in México. Despite this, Cervical Cancer continues to have a late diagnosis which leads to a high rate of complications. Pain represents the most feared and disabling symptom, being present in up to 86% of patients with advanced disease. The approach to managing pain in this population has not been studied and described to a full extent. In addition, there is a pressing need to provide concise recommendations to promote adequate pain control. We performed a review of the literature in CC and had experts in the field of pain management evaluate the evidence found. We then issued relevant recommendations on pharmacology and interventional pain management. Thus, the approach to pain management must be comprehensive and individualized, considering the timely and appropriate use of pharmacologic treatment as well as interventional procedures.

RESUMEN

Background: Intravascular ultrasonography (IVUS) has become an important complementary tool in interventional cardiology, both for preprocedural planning and for optimizing the performance of percutaneous coronary intervention (PCI). However, this tool is not free of potential complications, because of that it is essential to be aware of them and their management. Over time, new uses of IVUS have emerged, and it is currently a potential tool for predicting the risk of coronary perforation. Case report: We present the clinical case of a 51-year-old male patient who was admitted in the context of post-infarction angina. During coronary angiography, the patient presented with two acute complications, one of them associated with IVUS and the other associated with severe coronary calcification that predisposed to coronary perforation. Both complications were successfully treated. Conclusion: IVUS, although a very useful imaging tool before and during PCI, is not without risk. The overall rate of complications with certain or possible relation to IVUS is 3.9%. Vascular spasm is the most frequent complication and acute vascular occlusion, with the need for emergency coronary artery by-pass grafting, the least frequent. On the other hand, IVUS can predict the risk of developing other complications, such as coronary perforation, by means of the C-CAT sign. Knowledge of the possible complications during PCI and the rapid procedure of the hemodynamic team allows adequate management of these potentially fatal complications.

RESUMEN

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.

RESUMEN

Diagnostic reference levels (DRLs) are a pivotal strategy to be implemented since pediatric interventional cardiology procedures are increasing. This work aimed to propose an initial set of Brazilian DRLs for pediatric interventional diagnostic and therapeutic (D&T) procedures. A retrospective study was carried out in four Brazilian states, distributed across the three regions of the country. Data were collected from pediatric patients undergoing cardiac interventional procedures (CIPs), including their age and anthropometric characteristics, and at least four parameters (number of images, exposure time, air kerma-area product-PKA, and cumulative air kerma). Data from 279 patients undergoing CIPs were gathered (147 diagnostic and 132 therapeutic procedures). There were no significant differences in exposure time and the number of images between the D&T procedures. A wide range of PKA was observed when the therapeutic procedures were compared to diagnostics for all age groups. There were significant differences between the D&T procedures, whether grouping data by patient weight or age. In terms of cumulative air kerma, it was noted that no value exceeded the level to trigger a monitoring process for patients. This study shows that it is possible to adopt them as the first proposal to establish national DRLs considering pediatric patient groups.

RESUMEN

Background: Congenital heart disease is the most common birth defect and the leading cause of childhood mortality in high-income countries. In these countries, the prognosis for a child born with congenital heart disease is excellent, with over 90% achieving adulthood. However, in the low and lower-middle-income countries, as ours, the outlook is starkly different. In Chiapas, because of the progress of the hemodynamics program, more and more types of congenital heart diseases are susceptible to being treated by cardiac catheterization. Objective: To show the global experience of the interventionism in congenital heart diseases in Chiapas from its inception to recent days. Method: Through a retrospective study from April 2016 to June 2023, we reviewed the electronic files of the total of patients who underwent cardiac catheterism during the same period of time. Results: A total of 1000 procedures were performed, 581 in female patients, with a median age of 4 years (1 day to 77 years). Of the total procedures, 115 (11.5%) were diagnostic catheterizations and 885 (88.5%) were interventional. Conclusions: Cardiac catheterization in pediatrics in Chiapas has displaced cardiac surgery in a large percentage, and the results that have been obtained are undoubtedly encouraging, which already represents a decentralization in the care of congenital heart diseases in our country.

Antecedentes: Las cardiopatías congénitas son el defecto congénito más común y la primera causa de mortalidad infantil en los países de alto ingreso económico. En estos países, el pronóstico de los pacientes nacidos con estos defectos es excelente, llegando el 90% de ellos hasta la edad adulta. Sin embargo, en los países de mediano o bajo ingreso económico, como el nuestro, el pronóstico es completamente distinto. En el Estado de Chiapas, como resultado del avance del programa de hemodinamia, cada vez más tipos de cardiopatías congénitas son susceptibles de ser tratadas por cateterismo cardiaco. Objetivo: Mostrar la experiencia global actual de la hemodinamia en cardiopatías congénitas en Chiapas después de haber alcanzado los primeros 1000 casos realizados desde el inicio de nuestro programa. Método: A través de un estudio retrospectivo que abarcó de abril de 2016 a junio de 2023 revisamos los expedientes electrónicos del total de pacientes que fueron llevados a cateterismo cardiaco durante ese periodo. Resultados: Se realizaron un total de 1000 procedimientos, 581 en pacientes del sexo femenino, con una mediana de edad de 4 años (1 día a 77 años). Del total de los procedimientos, 115 (11.5%) fueron cateterismos diagnósticos y 885 (88.5%) intervencionistas. Conclusiones: El cateterismo cardiaco en cardiopatías congénitas en el Estado de Chiapas ha desplazado a la cirugía cardiaca en un amplio porcentaje, y los resultados obtenidos son sin duda alentadores, lo cual representa ya una descentralización en la atención de las cardiopatías congénitas en nuestro país.

RESUMEN

Cystic artery pseudoaneurysm (CAP) is a rare entity, with just a few cases reported in the literature. The most common presentation of CAP is described by Quincke's triad of upper gastrointestinal bleeding, jaundice and right upper quadrant abdominal pain. We report the case of an 83-year-old male who presented to the adult emergency with a history of an acute cholecystitis 5 weeks prior for which responded to conservative management. Despite this patient not presenting with Quincke's triad, early suspicion of CAP was considered in light of his history of acute cholecystitis and a computed tomographic CT abdomen ordered promptly which showed a 6 mm cystic artery pseudoaneurysm and a thick-walled gallbladder with surrounding inflammatory changes. Management with an endovascular approach followed by an elective cholecystectomy was done.

RESUMEN

BACKGROUND: Endovascular management of portal vein thrombosis (PVT) is challenging. Transsplenic access (TSA) is growing as an access option to the portal system but with higher rates of bleeding complications. The aim of this article is to evaluate the efficacy and safety of transsplenic portal vein recanalization (PVR) using a metallic stent after pediatric liver transplantation. MATERIALS AND METHODS: This is a retrospective review of 15 patients with chronic PVT who underwent PVR via TSA between February 2016 and December 2020. Two children who had undergone catheterization of a mesenteric vein tributary by minilaparotomy were excluded from the patency analysis but included in the splenic access analysis. The technical and clinical success of PVR and complications related to the procedure via TSA were evaluated. RESULTS: Thirteen children with PVT were treated primarily using the TSA. The mean age was 4.1 years (range, 1.5-13.7 years), and the most common clinical presentation was hypersplenism (60%). Technically successful PVR was performed in 11/13 (84.6%) children, and clinical success was achieved in 9/11 (81.8%) children. No major complications were observed, and one child presented moderate pain in the TSA (from a total of 17 TSA). The median follow-up was 48.2 months. The median primary patency was 9.9 months. Primary patency in the first 4 years was 75%, and primary assisted patency was 100% in the follow-up period. CONCLUSIONS: Transsplenic PVR is a safe and effective method for the treatment of PVT after pediatric liver transplantation.

RESUMEN

Abstract Background and objectives: Chronic shoulder pain is a frequent cause of suffering and impaired quality of life. Treatment includes non-pharmacological and pharmacological therapies, and interventional procedures such as suprascapular nerve blocks and radiofrequency. This prospective study aims to evaluate the efficacy of ultrasound-guided pulsed radiofrequency of suprascapular nerve for chronic shoulder pain in a clinical setting. Methods: Therapeutic efficacy was evaluated through pain intensity using numeric pain rating scale at baseline, immediately, 3, and 6 months after, and patient's motor function improvement. The secondary outcome was patient satisfaction. Results: A total of 34 patients were enrolled and all patients presented a reduction in the numeric pain rating scale immediately after treatment. Pain reduction from baseline to 6 months after the procedure was 34.4% and 36.9% static and dynamic, respectively. The median percentage reduction was statistically significant immediately, 3 and 6 months after. There was also an improvement in range of motion, 39.6% in abduction, 24.1% in flexion, and 29.5% in extension. Ninety percent of patients reported patient's global impression of change superior to six. Conclusion: This study concludes that ultrasound-guided pulsed radiofrequency of suprascapular nerve reduces pain intensity for at least 6 months, accompanied by improvement of motor function and higher levels of patients' satisfaction. Therefore, this technique represents a valid analgesic approach to chronic shoulder pain.

RESUMEN

SUMMARY OBJECTIVE: Thoracic ultrasonography is widely used in imaging peripheral lesions and invasive interventional procedures. The aim of this study was to assess the diagnostic value of thoracic ultrasonography-guided transthoracic needle aspiration biopsy and the factors affecting the diagnosis of peripheral tumoral lung lesions. METHODS: The lesion size, biopsy needle type, number of blocks, complications, and pathology results were compared in 83 patients between January 2015 and July 2018. The cases with pathological non-diagnosis and definite pathological diagnosis were determined. For the assessment of the factors affecting diagnosis, the size of the lesions and the biopsy needle type were evaluated. Biopsy preparations containing non-diagnostic atypical cells were referred to a cytopathologist. The effect of the cytopathological examination on the diagnosis was also evaluated. RESULTS: Pathological diagnosis was made in 66.3% of the cases; cell type could not be determined in 22.9% of the cases, and they were referred to a cytopathologist. After the cytopathologist's examination, the diagnosis rate increased to 80.7%. Diagnosis rates were higher when using tru-cut than Chiba and higher in cases with tumor size >2 cm than smaller. CONCLUSION: Thoracic ultrasonography-guided transthoracic needle aspiration biopsy is a preferred approach to the diagnosis of peripheral tumoral lung lesions, given its high diagnostic rate, in addition to being cheap, highly suitable for bedside use, and safe, and the lack of radiation exposure.

RESUMEN

ABSTRACT Objectives: To study the complications and effectiveness of the treatment of chronic arrhythmias with cardiac Ganglion Plexus (GP) ablation, and to explore the value of the treatment of chronic arrhythmias with GP ablation. Methods: This study was a one-arm interventional study of patients from the first hospital of Xinjiang Medical University and the People's Hospital of Xuancheng City admitted (09/2018-08/2021) because of bradyarrhythmia. The left atrium was modeled using the Carto3 mapping system. The ablation endpoint was the absence of a vagal response under anatomically localized and high-frequency stimulation guidance. Postoperative routine follow-up was conducted. Holter data at 3-, 6-, and 12-months were recorded. Results: Fifty patients (25 male, mean age 33.16 ± 7.89 years) were induced vagal response by either LSGP, LIGP, RAGP, or RIGP. The heart rate was stable at 76 bpm, SNRT 1.092s. DC, DR, HR, SDNN, RMSSD values were lower than that before ablation. AC, SSR, TH values were higher than those before ablation, mean heart rate and the slowest heart rate were significantly increased. There were significant differences in follow-up data between the preoperative and postoperative periods (all p < 0.05). All the patients were successfully ablated, and their blood pressure decreased significantly. No complications such as vascular damage, vascular embolism and pericardial effusion occurred. Conclusions: Left Atrial GP ablation has good long-term clinical results and can be used as a treatment option for patients with bradyarrhythmia.

RESUMEN

ABSTRACT There is increasing interest in ultrasound-guided ablation treatments for thyroid diseases, including benign and malignant ones. Surgeons, radiologists, and endocrinologists carry out these treatments, and various organizations within these specialties have recently released multiple international consensus statements and clinical practice standards. The aim of the present consensus statement is to provide guidance, cohesion, and standardization of best practices for thermal ablation procedures of thyroid nodules. The statement includes the indications for these procedures, preprocedural evaluations, technical aspects of the procedures, posttreatment care, follow-up, complications, and training recommendations. This document was written by a panel of specialists from the Brazilian Society of Interventional Radiology and Endovascular Surgery (SOBRICE), the Brazilian Society of Head and Neck Surgery (SBCCP), and the Brazilian Society of Endocrinology and Metabolism (SBEM). The statement does not aim to provide criteria for assessing the capability of specialists to perform the procedure. Instead, it aims to promote the standardization of best practices to reduce potential adverse outcomes. Additionally, it strives to enhance the delivery of high-quality care and the widespread adoption of these technologies on a national level. The recommendations collectively serve as a guidebook for applying best practices in thyroid ablation.

RESUMEN

BACKGROUND: To estimate the contemporary prevalence of established cardiovascular disease (CVD) in adults with type 2 diabetes (T2D) in Mexico. METHODS: CAPTURE was a multinational, non-interventional, cross-sectional study across 13 countries from five continents. Standardized demographic and clinical data were collected from adults with T2D attending a single routine healthcare visit in primary or specialized care between December 2018 and September 2019. Data from Mexico are analyzed in this study. RESULTS: Of the 9,823 patients included in the CAPTURE study, 820 (8.3%) participants were from Mexico, mainly attended in private centers (29.3% in 6 specialized diabetes treatment centers and 70.7% in 26 primary care centers). The median age was 63.0 years, 52.6% were women, the duration of diabetes was 11.8 years and the average HbA1c 7.5%. The weighted prevalence [95% CI] of CVD and atherosclerotic CVD was 36.9% [34.1-39.6] and 29.5% [26.7-32.3], respectively. Additionally, the prevalence of coronary heart disease, heart failure, peripheral arterial disease and cerebrovascular disease was 23.1% [20.6-25-7], 8.4% [6.8-10.0], 5.0% [3.5-6.5] and 3.9% [2.6-5.2], respectively. Glucose lowering drugs were used in 88.5% of patients, being metformin the most commonly drug used (79.4%), followed by sulfonylureas (26.3%). SGLT-2 inhibitors and GLP1 receptor agonists were used in 15.5% and 3.9%, respectively. CONCLUSIONS: In Mexico, nearly four out of ten patients with T2D mainly attended in private centers have CVD, particularly atherosclerotic CVD. Most patients were not taking glucose lowering drugs with proven CV benefit.

RESUMEN

This article presents the development, advancements, challenges and achievements of the "Optimization of Protection in Pediatric Interventional Radiology in Latin America and the Caribbean" (OPRIPALC) program. This international initiative is led by the World Health Organization, the Pan American Health Organization and the International Atomic Energy Agency. The main objectives of OPRIPALC are to foster a culture of radiological protection in pediatric interventions, enhance these procedures' quality, and define optimization strategies such as the use of diagnostic reference levels (DRLs). Currently, 33 centers from 12 countries participate actively in the program. Significant progress has been made towards the proposed objectives, overcoming the challenges posed by the COVID-19 pandemic. Through many virtual meetings for coordination, planning, training and follow-up, a comprehensive set of DRLs for both diagnostic and therapeutic procedures, categorized by weight and age, have been established and are in use. A consensus document on good practices is in the final stage of development. The program's continuation into at least a second phase is essential to address pending issues, including the integration of automatic dose management systems, the levels of occupational radiation doses, their correlation with pediatric patient doses, and strategies to reduce them.
