Aneurysm of a saphenous vein bypass graft associated with aneurysms of native coronary arteries

Aneurysm formation in saphenous vein aortocoronary bypass grafts is an extremely rare complication of coronary artery bypass surgery. Aneurysms of native coronary arteries are found in a small percentage of patients at autopsy. Reported is a case with multiple coronary artery aneurysms in which a dissecting aneurysm of the saphenous vein bypass graft also developed following coronary artery bypass surgery. This is the first report of such association.
