A 77-year-old male with many comorbidities underwent off pump coronary artery bypass grafting. A severely atherosclerotic ascending aorta was revealed by preoperative computed tomography(CT) and epiaortic echography during operation. Therefore, V-composite saphenous vein grafting was adopted for non left anterior descending artery (LAD) coronary lesions in addition to left internal thoracic artery-left anterior descending artery bypass grafting. He was discharged with no complications and all grafts were confirmed to be patent by postoperative CT. V-composite saphenous vein grafting for avoiding cerebrovascular complications might be one of the useful options in coronary artery revascularization for non-LAD lesions in elderly patients or those with many comorbidities, especially with a severely atherosclerotic ascending aorta.
