[Coronary revascularization using an internal mammary artery-saphenous vein composite graft in a patient with severely calcified ascending aorta].
A 52-year-old woman with angina pectoris resulted from complete obstruction of left coronary ostium required double-vessel bypass. Because of severely calcified ascending aorta, avoidance of aortic cross-clamping was needed for the prevention of embolic injury and aortic dissection. Internal mammary artery (IMA)-saphenous vein (SV) composite graft under hypothermic ventricular fibrillation was successfully performed without any complication. IMA-SV composite graft is a good alternative in a case of insufficient IMA length and limited site for proximal vein graft anastomosis, which can avoid or reduce the manipulation of diseased ascending aorta.
