Radial artery grafts vs saphenous vein grafts in coronary artery bypass surgery: a randomized trial.

Context: Arterial grafts are thought to be better conduits than saphenous vein grafts for coronary artery bypass grafting (CABG) based on experience with using the left internal mammary artery to bypass the left anterior descending coronary artery. The efficacy of the radial artery graft is less clear.

Objective: To compare 1-year angiographic patency of radial artery grafts vs saphenous vein grafts in patients undergoing elective CABG.
