Randomized Controlled Trial Multicenter Study Comparative Study
Radial artery grafts vs saphenous vein grafts in coronary artery bypass surgery: a randomized trial.
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. ⋯ Among Veterans Affairs patients undergoing first-time elective CABG, the use of a radial artery graft compared with saphenous vein graft did not result in greater 1-year patency.
