Safety and Performance of a Cell-Impermeable Endoprosthesis for Hemodialysis Vascular Access Outflow Stenosis: A Brazilian Multicenter Retrospective Study.

Purpose: To evaluate the safety and performance of Wrapsody™, a cell-impermeable endoprosthesis (CIE), for treating hemodialysis vascular access outflow stenosis.

Materials And Methods: Investigators retrospectively analyzed 113 hemodialysis patients treated with a CIE (11/2021-12/2022) across four centers in Brazil. De novo or restenotic lesions were treated.

Safety and efficacy of a new covered stent in hemodialysis vascular access outflow stenosis: A Brazilian multicenter retrospective study.

Background: Vascular stenosis commonly leads to dysfunction in hemodialysis vascular access. Although percutaneous transluminal angioplasty is an established treatment, stent utilization has increased in the last decade as an alternative solution to extend the access function. This study evaluated the safety and initial results of a new impermeable covered stent for treating vascular access outflow stenosis.

Performance of ChatGPT on the Brazilian Radiology and Diagnostic Imaging and Mammography Board Examinations.

This prospective exploratory study conducted from January 2023 through May 2023 evaluated the ability of ChatGPT to answer questions from Brazilian radiology board examinations, exploring how different prompt strategies can influence performance using GPT-3.5 and GPT-4. Three multiple-choice board examinations that did not include image-based questions were evaluated: radiology and diagnostic imaging, mammography, and neuroradiology.

Guidelines on vascular access for hemodialysis from the Brazilian Society of Angiology and Vascular Surgery.

Chronic kidney disease is a worldwide public health problem, and end-stage renal disease requires dialysis. Most patients requiring renal replacement therapy have to undergo hemodialysis. Therefore, vascular access is extremely important for the dialysis population, directly affecting the quality of life and the morbidity and mortality of this patient population.

Endovascular treatment of aortic saccular aneurysms associated with Adamantiades-Behçet disease.

Adamantiades-Behçet disease is a multisystemic disorder that classically presents with oral and genital ulcers and ocular involvement, with vascular involvement in up to 38% of cases. Aortic involvement is one of the most serious manifestations and is associated with high mortality rates, occurring in 1.5 to 2.

Endovascular treatment of Nutcracker syndrome: case report.

Chronic pelvic pain is a debilitating disease that directly impacts on quality of life and generates costs for health services. Nutcracker Syndrome is an important cause of pelvic pain and consists of a set of signs secondary to compression of the left renal vein, most commonly between the superior mesenteric artery and the aorta. Treatment remains controversial and varies depending on the patient's clinical severity.

Association of aortic coarctation and malignant right coronary artery anomaly: an unusual cause of angina pectoris.

A 53-year-old man with exercise-induced ischemia was referred for investigation. Coronary angiography revealed a right coronary artery originating from the trunk of the left coronary artery, and an aortic coarctation was observed on aortography. A CT angiogram confirmed these findings.
