The benefits of coronary bypass surgery last only as long as the grafts continue to function. Aorta-to-coronary saphenous-vein grafts (see diagram), the most widely used type of bypass graft, have historically had an occlusion rate of 10 to 15 percent within a year after surgery. Beyond 5 years after surgery, graft atherosclerosis develops in substantial numbers of saphenous-vein grafts, and progressive graft failure occurs so that by 10 years after placement, 60 to 70 percent of grafts are patent and half of those have angiographic evidence of atherosclerosis. By 20 years after placement, the rate of graft patency appears . . . [Full Text of this Article]
