Abstract

Saphenous vein graft (SVG) aneurysm after coronary artery bypass grafting (CABG) is a rare complication. A fistula between an SVG aneurysm and a cardiac chamber is even rarer. Herein, we report a middle-aged man who underwent CABG with five grafts 13 years prior presenting with multiple aneurysms in the venous graft with a fistula between the aneurysm and the right atrium. The computed tomographic angiogram findings and the subsequent treatment of the patient are addressed in the report.

Keywords: CT coronary angiogram; right atrial fistula; saphenous graft aneurysm.
