[Large saphenous vein graft aneurysm after coronary artery bypass grafting].
A 64-year-old man underwent coronary artery bypass grafting (CABG) in 1994. Eleven years later, coronary angiography (CAG) showed a saphenous vein graft (SVG) aneurysm. In April 2008, the CAG demonstrated enlargement of the aneurysm. Enhanced computed tomography showed a large aneurysm measuring 53 x 44 mm in diameter of the SVG-right coronary artery (RCA) [#3] anastomosis. Off-pump coronary surgery to RCA and aneurysmectomy was planned through a median epigastric incision. However re-grafting was difficult because of severe adhesion and calcification of the coronary artery. We confirmed sufficient back flow from the distal coronary artery without hemodynamic and electrocardiographic changes under SVG clamp. Aneurysmectomy was then performed without coronary bypass. The patient was discharged 9 days after surgery and has been well for 8 months in outpatient clinic.
