Mycotic aortocoronary saphenous vein graft aneurysm presenting with unstable angina pectoris

We report the case of a 60-year-old man with a history of coronary bypass surgery 20 years prior who had a fever, chest pain, and a mediastinal mass develop after a complicated postoperative course of abdominal aortic aneurysm resection. A mycotic aneurysm of the saphenous vein graft to his left anterior descending coronary artery was diagnosed based on blood culture results and visualization of the aneurysm before resection. A summary of the saphenous vein graft aneurysm and pseudoaneurysm cause, diagnosis, and management is detailed. (C) 2004 by The Society of Thoracic Surgeons.
