Aortocoronary saphenous vein graft aneurysm in redo coronary artery bypass grafting: report of a case

Abstract

We report herein the case of an 80-year-old woman who underwent successful redo coronary artery bypass grafting (CABG) for a saphenous vein graft aneurysm found 10 years after her initial operation. On presentation, coronary angiography (CAG) revealed aneurysmal dilatation of the saphenous vein graft and severe stenosis of the left main trunk (LMT). A percutaneous transluminal coronary angioplasty (PTCA) of the LMT lesion was performed; however, a CAG after the PTCA revealed restenosis and the patient developed anginal chest pain at rest. Thus, repeat CABG was urgently carried out, which was followed by a good outcome. Histological examination of the aneurysmal dilatation showed a true aneurysm. Only 15 other cases of redo CABG for this indication have been reported, the features of which are also discussed.
