Twenty-three coronary bypass graft patients were evaluated by a contrast-enhanced computed tomography (CT) technique to determine graft patency. Four to six 4.8-second sequenced scans with a 1-second interscan interval were obtained in each patient during the hand injection of 25-30 ml of contrast medium in a peripheral vein. Patency of grafts was determined by a characteristic contrast enhance...

Background—The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial assigned patients with type 2 diabetes mellitus to prompt coronary revascularization plus intensive medical therapy versus intensive medical therapy alone and reported no significant difference in mortality. Among patients selected for coronary artery bypass graft surgery, prompt coronary revascularizat...

BACKGROUND Invasive coronary angiography is the gold standard means of imaging bypass vessels and carries a small but potentially serious risk of local vascular complications, including myocardial infarction, stroke and death. We evaluated computed tomography as a non-invasive means of assessing graft patency. METHODS Fifty patients with previous coronary artery bypass surgery who were listed...

OBJECTIVE The aim of this study was to assess the coronary vascular resistance (CVR) and to analyze the flow differences through grafts in coronary artery bypass graft surgery. METHODS Between 17 June and 15 July 2005, we assessed the coronary vascular resistance profile in 10 patients undergoing coronary artery bypass graft surgery by grafting a section of saphenous vein and checking CVR dir...

BACKGROUND The optimal conduit of second choice in surgical coronary revascularization remains a matter of debate. Radial artery grafts are believed to have a better patency rate than the saphenous vein grafts, although no conclusive results have been reported. This report describes the late result of a coronary revascularization with sequential venous bypass performed 30 years earlier. METHO...

OBJECTIVE We present operative results of aortic arch aneurysm associated with coronary artery stenosis, and evaluate the operative risk of graft replacement of the aortic arch and concomitant coronary artery bypass grafting (CABG). PATIENTS AND METHODS From January 1991 to December 2001, we treated 16 patients with aortic arch aneurysm and coronary artery stenosis. The patients, 3 women and ...
