title: [Surgical repair for ascending aortic pseudoaneurysm derived from the proximal anastomotic site of saphenous vein graft after coronary artery bypass grafting; report of a case].
abstract: A 61-year-old male had undergone coronary artery bypass grafting (CABG) using a saphenous vein. Postoperative angiography represented an ascending aortic pseudoaneurysm derived from the proximal anastomotic site of the saphenous vein graft( SVG) which was connected to the obtuse marginal branch and left posterior descending branch sequentially. We performed the closure of tear and the plication of pseudoaneurysmal wall through median sternotomy on the 56th postoperative day. A 7mm length longitudinal tear in the ascending aorta close to the proximal anastomotic site of the SVG was observed. This tear was considered to be caused by the intimal injury during the anastomosis of SVG to ascending aorta. Aortic pseudoaneurysm formation close to the proximal anastomotic site of SVG is a rare and potentially lethal complication requiring urgent operation. Postoperative angiography or enhanced 3 dimensional computed tomography after CABG should be performed before hospital discharge.
