Progressive late obstruction of an aorto-coronary venous bypass graft is reported in a 44-year-old man who died of bi-ventricular failure 114 days after surgery. The first portion of the vein graft had a residual lumen of one mm. Histology showed marked intimal fibrosis. Mechanism for this occlusion and fibrosis is unclear. This representsc the first documented case of late obstruction of an ao...

OBJECTIVE The following report describes the experience of the Cardiovascular Surgery Team of the ABC Medical School with coronary-coronary bypass grafting. METHODS Four patients undergone off-pump coronary artery bypass grafting, with coronary-coronary bypass of the right coronary artery, by using great saphenous vein graft. RESULTS The follow-up period was 3 to 5 years without any intra- ...

OBJECTIVE The use of automatic anastomotic devices in coronary artery bypass grafting surgery is associated with lower patency rates in comparison to conventional anastomosis methods. This is thought to be caused by graft curvature occurring after closing of the chest wall. METHODS We evaluated 39 grafts in 28 patients who underwent off-pump coronary artery bypass surgery using the PAS-Port. ...

Left internal mammary artery grafting is commonly used in elective coronary artery bypass graft surgery. We report a near-fatal case with graft kinking upon sternal closure due to distended, emphysematous lungs impinging on the mammary graft. After the sternum was closed, the patient suffered a severe hemodynamic deterioration. Surgical examination revealed kinking of his left internal mammary ...

BACKGROUND Saphenous vein graft disease remains a major limitation of coronary artery bypass graft surgery. The process of saphenous vein intimal hyperplasia begins just days after surgical revascularization, setting the stage for graft atherosclerotic disease and its sequalae. Clopidogrel improves outcomes in patients with atherosclerotic disease, and is effective at reducing intimal hyperplas...

OBJECTIVES The aim of this article is to make an evaluation on the clinical features of patients with Kawasaki disease who require a cardiac surgical procedure including coronary artery bypass grafting, coronary arterial aneurysmorrhaphy or heart transplantation. METHODS English literature of Kawasaki disease for cardiac surgery (1990-2011) was retrieved in the Pubmed database. The clinical f...

widely used for patients with multivessel coronary artery disease. The post-operative patency of the bypass graft is important to predict the clinical outcome (1-3). Postoperative myocardial infarction is a rare, but potentially severe complication after CABG. So, the early recognition of the failure of a bypass graft on the early postoperative imaging is necessary to evaluate the quality of th...

BACKGROUND Although considerable efforts have been made to improve the graft patency in coronary artery bypass surgery, the role of biomechanical factors remains underrecognized. The aim of this study is to investigate the influences of geometric configurations of the bypass graft on hemodynamic characteristics in relation to anastomosis. MATERIALS AND METHODS The Numerical analysis focuses o...
