1. COVID-19 - Endothelial Axis and Coronary Artery Bypass Graft Patency: a Target for Therapeutic Intervention?
Abstract It has been reported that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection induces endothelial inflammation, therefore facilitating the progression of endothelial and vascular dysfunction in coronavirus disease 2019 (COVID-19) patients. Coronary artery bypass grafting (CABG) involves mainly the use of the saphenous vein (SV) an

2. Why Use the Radial Artery? The Saphenous Vein is the Second Graft of Choice for CABG in Brazil
Abstract The saphenous vein (SV) is the most commonly used conduit for coronary artery bypass surgery (CABG) and the second conduit of choice in Brazil and many other countries. The radial artery (RA) is suggested, by some, to be superior to SV grafts, although its use in the USA declined over a 10 year period. The patency of SV grafts (SVG) is improved when

3. Relevance of a skilled vascular surgeon and optimized facility practices in the long-term patency of arteriovenous fistulas: a prospective study
Resumo Introdução: Fístulas arteriovenosas (FAV) são os melhores acessos vasculares para hemodiálise, mas sua taxa de falhas permanece alta. Poucos estudos abordaram o papel das habilidades do cirurgião vascular e das práticas hospitalares. Nosso objetivo foi avaliar esses fatores, com a hipótese de que as habilidades do cirurgião e as práticas ho

4. Tratamento da doença arterial obstrutiva periférica em território femoropoplíteo com stent primário: análise em até 24 meses
Resumo Contexto O stent primário é uma opção de tratamento bem estabelecida para a doença arterial periférica em território femoropoplíteo. Estudos nacionais são escassos. Objetivos Avaliar desfechos clínicos e radiológicos em curto e médio prazo em pacientes classificados como Rutherford 3-6, tratados com o uso de stent em lesões femoropopl

5. Experimental implantation of an arterial substitute made of silicone reinforced with polyester fabric in rabbits
OBJECTIVES: The aim of this study was to analyze silicone tubes with an internal diameter of 4 mm as a possible material for vascular prostheses. METHODS: Grafts were implanted into the infrarenal aortas of 33 rabbits. Fluoroscopic examinations were performed within 150 days after surgical implantation. Sample grafts were analyzed via electron microscopy t

6. Experimental Model of Saccular Abdominal Aortic Aneurysm in Swines with Pericardium Sac
Abstract Objective: To consider modifications in an experimental model of saccular aortic aneurysm, aiming at better reproducibility, to be used in the development of vascular prostheses. Methods: Experimental study in two phases, developed in the Center of Experimental Surgery and Bioterium (CCEB) of the University of Health Sciences of Alagoas (UNCISAL),

7. An experimental model to retraining in microvascular suture
PURPOSE:To demonstrate an experimental model of up to four hours a week of independent study that allows relearning in microvascular sutures.METHODS:Wistar rats between 200 and 500 grams surplus research experiments were used. Femoral vessels are covered on one or both sides through a groin incision obliquely along the inguinal ligament. Femoral artery and v

8. Estudo prospectivo e randomizado da revascularização do miocárdio minimamente invasiva com dissecção da artéria torácica interna esquerda por videotoracoscopia robótica / Robotic left internal mammary artery harvesting for single vessel minimally invasive coronary bypass: a randomized controlled trial
Objective: The aim of this study was to compare the patency of left internal mammary artery (LIMA) robotically harvested for left anterior descendent (LAD) artery minimally invasive bypass with conventional LIMA to LAD off-pump bypass. Method: From 2007 to 2010, 36 patients were randomized to either LIMA robotically harvested to LAD artery minimally invasive

9. Assessment of blood flow in perforating arteries during intracranial aneurysm surgery with intraoperative videoangiography using indocyanine green / Avaliação do fluxo sanguíneo em artérias perfurantes durante a cirurgia de aneurismas intracranianos através da video-angiografia intra-operatória utilizando indocianina verde
Background. Perforating arteries are commonly involved during the surgical dissection and clipping of intracranial aneurysms. Occlusion of perforating arteries may be responsible for ischemic infarction and poor outcome. The goal of this study was to describe the usefulness of near-infrared indocyanine green videoangiography (ICGA) for the intraoperative ass

10. Pilot study of the impact of antiproliferative therapy with everolimus administered orally in the reduction of restenosis after implantation of selfexpandable nitinol stent for treatment of occlusive lesions of the superficial femoral artery / Estudo piloto do impacto da terapia antiproliferativa com everolimus administrado por via oral na diminuição de reestenose após implante de stent auto-expansível de nitinol para tratamento de lesões oclusivas da artéria femoral superficial
INTRODUCTION: The implantation of a self-expanding of nitinol stent in the treatment of femoropopliteal occlusive lesions has been associated with a poor outcome in a long term setting. Everolimus administered orally to inhibit restenosis of the stent was investigated recently in animals with good results, but its safety and efficacy has not been studied in

11. Cardiac and vascular effects of diltiazem, dobutamine and amrinone, drugs used after myocardial revascularization
Hemodynamic care during postoperative management of myocardial revascularization should include vasorelaxing drugs to insure adequate graft and coronary flow, and stimulation of stroke volume to maintain vascular perfusion pressure. We tested the cardiac (inotropic and lusitropic) and vascular (relaxant) effects of diltiazem (0.1 nM to 0.1 mM), dobutamine (1
