Large aneurysm in saphenous vein coronary artery graft with fistula: case report and review.

Aneurysms developing in a saphenous vein graft (SVG) after coronary artery bypass grafting (CABG) are an unusual complication and fistulae forming between an SVG aneurysm and a cardiac chamber are even rarer. A 71-year-old man had undergone a triple CABG with the left internal thoracic artery and double SVGs. Twenty years later, he was admitted with repeated congestive heart failure. A large true aneurysm (99 × 60 mm) developed in the mid portion of a saphenous vein graft to the right coronary artery together with a fistula with a diameter of 8 mm in the right atrium. The aneurysm was surgically resected and the fistula was closed.
