Radial artery bypass grafts have an increased occurrence of angiographically severe stenosis and occlusion compared with left internal mammary arteries and saphenous vein grafts.
BACKGROUND The radial artery has been increasingly used in CABG. However, angiographic outcome data have been limited. METHODS AND RESULTS We reviewed all coronary angiography procedures from February 1996 to October 2001 and selected patients with a radial artery bypass graft. Angiographic outcomes were divided into groups as (1) occluded, (2) severe disease (> or =70% stenosis, or string si...
متن کاملA Comparison of Internal Mammary Artery and Saphenous Vein Grafts After Coronary Artery Bypass Surgery
Background Superior patency rates for internal mammary artery (IMA) grafts compared with vein coronary bypass grafts have been demonstrated by retrospective studies. This difference may have been affected by selection bias of patients and coronary arteries for IMA grafting. Methods and Results To estimate the difference between IMA and vein grafts, we analyzed graft patency data of 912 patients...
متن کاملState of the vein grafts, native coronary arteries, and myocardium and principal cause of death in patients dying after aortocoronary bypass grafting.
Fifty five patients with 108 coronary bypass saphenous vein grafts were studied at necropsy. The mean duration of the grafts was 153 days (SD 516). The luminal narrowing of the native coronary arteries proximal to, at, and distal to the vein graft anastomoses and the narrowing of the non-grafted arteries were evaluated planimetrically. Twenty nine per cent of coronary arteries distal to graft a...
متن کاملRemodeling leads to distinctly more intimal hyperplasia in coronary than in infrainguinal vein grafts.
BACKGROUND Flow patterns and shear forces in native coronary arteries are more protective against neointimal hyperplasia than those in femoral arteries. Yet, the caliber mismatch with their target arteries makes coronary artery bypass grafts more likely to encounter intimal hyperplasia than their infrainguinal counterparts due to the resultant slow flow velocity and decreased wall stress. To al...
متن کاملAdaptive mechanisms of arterial and venous coronary bypass grafts to an increase in flow demand.
OBJECTIVE To compare the mechanisms by which arterial and venous grafts increase their flow during pacing induced tachycardia, early and later after coronary bypass surgery. DESIGN 43 grafts (13 epigastric artery, 15 mammary artery, 15 saphenous vein) evaluated early (9 (3) days (mean (SD)) after bypass surgery were compared with 41 other grafts (15 epigastric, 11 mammary, 15 saphenous vein) ...
