Aortocoronary saphenous vein bypass aneurysm--an unusual presentation

Abstract

Aneurysms of aortocoronary saphenous bypass grafts are an unusual and rare complication of coronary artery bypass surgery. Approximately 30 such cases have been reported in the literature. Atheromatous aneurysms usually appear late (more than 10 years after grafting). They are usually asymptomatic, but may manifest for investigation as a lesion altering the mediastinal contour. We report a further case of an atherosclerotic aortocoronary saphenous vein graft aneurysm in which the patient presented with angina due to aneurysmal compression of the host vessel.
