A large coronary artery saphenous vein bypass graft aneurysm with a fistula: Case report and review of the literature

We describe a patient who developed a large aneurysm of saphenous vein graft to the right coronary artery with a fistulous communication to the right atrium. The presence of a fistulous communication of a saphenous vein graft aneurysm after coronary bypass surgery to one of the heart chambers is extremely rare. The diagnosis was made by coronary angiography and confirmed by CT and MRI. At surgery the aneurysm was ligated and excised. The fistula to the right atrium was closed. Repeat coronary artery bypass surgery with aortic valve replacement was performed at the same time without complications. Cathet. Cardiovasc. Intervent. 48:214–216, 1999. © 1999 Wiley‐Liss, Inc.
