Aortic pseudoaneurysm after ligation of aneurysmal saphenous vein graft

After an aneurysmal saphenous vein graft was ligated and divided at reoperation, the proximal stump continued to enlarge, rather than occluding by thrombosis, producing an aortic pseudoaneurysm that compressed adjacent cardiac structures. Oversewing the aortosaphenous junction of ligated vein graft remnants will prevent this complication.
