2. 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

3. Allium sativum Compared to Cilostazol as an Inhibitor of Myointimal Hyperplasia
Abstract Objective: Intimal hyperplasia is associated with graft failure and vascular sutures in the first year after surgery and in postangioplasty restenosis. Allium sativum (common garlic) lowers cholesterol and has antioxidant effects; it also has antiplatelet and antitumor properties and, therefore, has great potential to reduce or inhibit intimal hype

4. The effect of losartan on angiotensin II-induced cell proliferation in a rat aorta smooth muscle cell line
The success of revascularization procedures is limited by recurrent stenosis, which is a narrowing of a blood vessels that results from neo-intimal hyperplasia. The renin-angiotensin-aldosterone system has been implicated in the pathogenesis of neo-intimal hyperplasia, and a role for angiotensin II in vascular smooth muscle cell proliferation has been propos

5. Histomorphometric and sympathetic innervation of the human internal thoracic artery
INTRODUCTION: Internal thoracic artery (ITA) is an established arterial graft for the coronary artery by-pass surgery. Special micro-anatomical features of the ITA wall may protect it from age related pathological changes. One of the complications seen after coronary artery bypass grafting is vasospasm. Sympathetic nerves may be involved in vasospasm. OBJECT

6. Postangioplasty restenosis : a practical model in the porcine carotid artery
Transluminal coronary angioplasty is a routine therapeutic intervention in coronary heart disease. Despite the high rate of primary success, restenosis continues to be its major limitation. Porcine models have been considered to be the most adequate experimental models for studying restenosis. One limitation of porcine models is the need for radiological gui

7. Análise histológica e histomorfométrica de carótidas após o implante de stent de cromocobalto sem e com revestimento de polímero : modelo experimental porcino
Introdução: Apesar dos avanços significativos no tratamento endovascular das doenças arteriais coronarianas e periféricas, a reestenose intra-stent continua sendo o principal limitante a médio prazo desses procedimentos. O mecanismo da reestenose intra-stent é principalmente a hiperplasia intimal, já que o stent impede a retração elástica aguda e

8. Análise morfométrica da carótida de suínos submetidos à angioplastia com implante de stent de cromo-cobalto
OBJETIVO: analisar, por meio de morfometria digital, a reação intimal presente na artéria carótida de suínos submetidos à angioplastia isoladamente e à angioplastia seguida de implante de stent de cromo - cobalto. MATERIAIS E MÉTODOS: em oito suínos sadios foi realizada a angioplastia isolada da artéria carótida comum (ACC) direita e angioplastia

9. The composite aortic wall graft technique: an option for a short coronary artery bypass graft
SUMMARY: During coronary artery bypass graft (CABG) surgery, the saphenous vein is sutured through its proximal segment to the aorta. Intimal hyperplasia is one of the possible causes of graft occlusion. Notably, blood turbulence can induce wall shear stress that may also play an important role in this process. OBJECTIVE: We propose a new technique for perfo

10. Self-expandable nitinol stent placement in homocysteinemic porcine aorta
PURPOSE: To compare aortic intimal thickening of normal and hyperhomocysteinemic pigs (induced with a methionine-rich diet) following placement of a self-expanding nitinol stent. METHODS: Eighteen Macau pigs were used. They were older than eight weeks in age and had an average weight of 30 kg. Pigs were randomly divided into two groups. The first, Group C (c

11. Efeito da dexametasona veiculada por stent biodivysio DD PC sobre a hiperplasia neo-intimal em artéria coronária : uma avaliação ultra-sonográfica / Effect of dexamethasone driven by Stent Biodivysio DD PC on neo-intimal coronary artery hyperplasia: an ultrasonographic evaluation
A reestenose ainda é o principal problema da angioplastia coronária, como ficou evidente nas revisões angiográficas dos primeiros procedimentos feitos por Gruntzig. Desde então se procura a solução. Várias drogas administradas por via sistêmica foram testadas, mas com nenhuma se obteve êxito. Aterectomia, angioplastia com raios laser e braquiterapi

12. Arterial intimal hyperplasia with intraluminal hemispherical plug stenosis: a morphologic and ultrastructural study / "Hiperplasia intimal arterial decorrente de um modelo experimental de estenose aórtica intrínseca: estudo morfológico, morfométrico e ultraestrutural"
O objetivo do presente trabalho foi avaliar a morfologia e a ultraestrutura da hiperplasia intimal arterial decorrente de um modelo de estenose aórtica experimental, através da inserção de um pino de acrílico no orifício da artéria renal esquerda. Realizamos um estudo morfológico e ultraestrutural em 64 ratos Wistar, machos, com peso médio de 250 g,
