title: Venous intimal hyperplasia with occlusion of the anastomosis between saphenous vein graft and carbo-seal dacron tube after a modified Bentall procedure.
abstract: In patients who require concomitant ascending aortic replacement and coronary artery bypass grafting, the proximal anastomosis is often constructed on a Dacron prosthesis. Herein, the case is reported of a 57-year-old female patient who developed global myocardial infarction at 20 months after redo ascending aortic surgery. Pathology revealed severe venous intimal hyperplasia that caused ostial occlusion of the proximal anastomosis between the saphenous vein graft and the Dacron prosthesis.
