[Coronary artery bypass grafting using gastroepiploic artery].
Since March 1986, coronary artery bypass grafting (CABG) by utilizing the right gastroepiploic artery (GEA) has been performed in 60 patients during 3 year period. There were 52 males and 8 females, and age ranged from 34 to 73 year old with the mean of 56.2 year old. Triple vessel disease and the left main disease involved 90% of the patients. There were two patients under hemodialysis for chronic renal failure, one patient with idiopathic thrombocytopenic purpura, one patient with aneurysm of the abdominal aorta, and two patients with arteriosclerosis obliterance, preoperatively. Five patients were second CABG. GEA was used as an in-situ graft in 57 patients and as a free graft in 3 patients and was anastomosed to 3 left anterior descending, 3 diagonal (all "free" graft), 5 circumflex, and 49 right coronary arteries. To bypass the other coronary arteries, the internal mammary artery graft (unilateral 38, bilateral 20, sequential 5) with or without saphenous vein graft was used. The mean number of distal anastomoses was 3.3 (1-5) and the mean number of arterial graft anastomoses was 2.4 (1-4) per patient with the mean aortic cross clamp time of 62.4 minutes (23-137 minutes) and the mean cardiopulmonary bypass time of 120.8 minutes (69-210 minutes). Splenectomy, Y graft replacement of the abdominal aorta, and ascending aorta-bifemoral bypass were concomitantly carried out in each one patient. Two patients (3.3%) died of renal and cardiac failure within 30 postoperative days. One patient (1.7%) died of stroke lately. New Q wave was noted in 2 patients.(ABSTRACT TRUNCATED AT 250 WORDS)
