An autopsy case of the rupture of a giant aneurysm in a saphenous vein graft: 18 years after CABG.

The saphenous vein is a widely used blood vessel for arterial bypass procedures. Failures of saphenous vein aortocoronary bypass grafts are predominantly the result of subsequent vein graft atherosclerotic disease. Rarely saphenous vein grafts undergo aneurysmal degeneration. This report describes a case of a ruptured aneurysm in a saphenous vein graft that occurred in an 82-year-old female who underwent a coronary artery bypass operation 18 years previously. We could not resuscitate her, but describe the autopsy findings in detail.
