Early Results of Fenestrated and Branched Endovascular Repair of Complex Aortic Aneurysms with a Custom-made National Device Available in the Brazilian Public Health System.

Background: Multicenter studies conducted in developed countries demonstrated that custom-made devices are safe, effective, and durable for treating complex abdominal aneurysms. However, the situation in developing countries, such as Brazil, is different. Funding and time to have the endoprosthesis delivered are the major concerns.

Short-Term Outcomes of Transfemoral Carotid Artery Stenting and Carotid Endarterectomy in Symptomatic Patients: Data from a Multicentric Prospective Registry in Brazil.

Background: Transfemoral carotid artery stenting (TF-CAS) and carotid endarterectomy (CEA) are alternative strategies for stroke prevention in patients with atherosclerotic carotid disease. Because their main objective is to prevent future ischemic events, regular reassessment of the outcomes is mandatory for providing the best therapy. The purpose of this study was to describe the practice and the outcomes of TF-CAS and CEA in symptomatic patients in public university hospitals in Brazil, using data from a prospective multicentric registry.

Free-floating thrombus in lower limb deep veins and May-Thurner syndrome: case report.

Free-floating thrombus in the deep venous system has a high potential to cause pulmonary embolization. It can also be found in patients with superficial venous thrombosis (SVT) that extends to a deep vein. There are still no defined criteria for treatments described in the literature, which range from anticoagulation and fibrinolytic treatments with vena cava filter implants, through open or endovascular thrombectomies, to more invasive procedures such as surgical interruption with ligation of the venous system.

Prophylactic catheterization of uterine arteries with temporary blood flow occlusion in patients at high risk of pospartum hemorrhage: is it a safe technique?

Background: Placenta accreta is an important factor in maternal morbidity and mortality and is responsible for approximately 64% of emergency hysterectomy cases and about 2/3 of cases of puerperal bleeding.

Objectives: To describe a series of cases of prophylactic uterine catheterization performed to prevent significant postpartum bleeding or during caesarean delivery in pregnant women with a previous diagnosis of accretion.

Methods: A retrospective analysis was conducted of medical records of cases of uterine artery catheterization performed during elective or emergency caesarean sections of patients at high risk of postpartum bleeding.

An Observational Registry of Carotid Endarterectomy and Carotid Artery Stenting in Brazil: Study Protocol.

Background: Carotid artery stenting (CAS) and carotid endarterectomy (CEA) are alternative strategies for stroke prevention in patients with atherosclerotic carotid disease. CEA has been considered the first-line treatment for carotid stenosis worldwide, and the safety and efficacy of CAS compared to CEA remains in question.

Objective: The purpose of this study is to compare the practice and outcomes of CAS and CEA in a real-world setting within public university hospitals in Brazil.

Percutaneous transluminal angioplasty in the treatment of stenosis of arteriovenous fistulae for hemodialysis.

Background: Thrombosis following stenosis of arteriovenous fistulae resulting in the loss of vascular access for hemodialysis is an important complication in patients with chronic renal failure. Percutaneous transluminal angioplasty is being used more frequently in the treatment of stenosis aiming at increasing the patency of arteriovenous fistulae.

Objective: To evaluate the primary patency of arteriovenous fistulae following percutaneous transluminal angioplasty.
