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)

From March 1986 to October 1989, 91 patients underwent CABG using the right gastroepiploic artery (GEA) at Osaka Medical College and Mitsui Memorial Hospital. Including 14 females, the mean age was 57.9 years old ranged from 34 to 73 years old. Triple vessel disease and left main disease occupied over 90% of the patients. There were 5 emergency operations and 6 reoperations. Associated serious diseases were; renal failure with hemodialysis in 2 pts., familial hyperlipidemia in 5 pts., severe atherosclerotic ascending aorta in 8 pts., arteriosclerosis obliterance in 3 pts., and each one of abdominal aortic aneurysm and idiopathic thrombocytopenic purpura. The internal thoracic artery (ITA) graft was concomitantly utilized in 96% of the patients. Single ITA in 60 pts., double ITA in 23 pts. and sequential ITA in 5 patients. Saphenous vein graft was used in 58 patients and remaining 33 patients were operated without leg wound. The mean number of distal anastomoses was 3.3 ranged from 1 to 5, and the mean number of arterial grafts was 2.5 ranged from 1 to 4. The mean aortic cross clamp time and cardiopulmonary bypass time was 62.8 minutes and 113.6 minutes, respectively. Sites of GEA anastomosis were; 4 anterior descending, 3 diagonal, 11 circumflex and 73 right coronary arteries. There were 86 in situ grafts mostly for the right coronary arteries, and remaining 5 GEAs were used as a free graft to bypass the left coronary arteries. On the contrary, ITA was used to bypass the left coronary artery system preferentially. There was 3 combined procedures; splenectomy, abdominal aorta replacement, and ascending aorta to bifemoral artery bypass in each one patients. Three patients including one emergency case died within 30 days after surgery. Two were cardiac and one was renal failure. Other 2 patients died of stroke at late period. New Q wave infarction was noted in 2 patients. Relief of angina was obtained in 98% of survivors. The patency rate of the GEA graft was 97% in 61 grafts restudied within 6 postoperative months, which was identical with that of the ITA graft, that is 97% of 76 grafts. In conclusion, the GEA has several advantages as a coronary artery bypass graft such as similarity in size to the coronary artery, rare arteriosclerosis, feasibility of in situ graft, and no gastric complication. Its flow capacity is studying now and favourable results are being obtained. The final problem, its long term patency, will be resolved in future. GEA is a promising conduit for the coronary bypass surgery.

Coronary artery diseases is rapidly increasing in our part of the world. The South Asian ethnic groups are especially vulnerable to coronary artery disease. The two most striking features of coronary artery disease in the South Asian population are extreme prematurity and severity of the disease, both resulting from the malignant atherosclerosis that begins at an earlier age than in other population. Triple vessel disease and complicated lesions are not common even in young people and follow a malignant course. The most important aspect of prevention is to identify individuals with high risk of coronary artery disease at an early age and aggressive modification of risk factors. Tobacco smoking and hypertension are the two most important risk factors for coronary heart disease and stroke. Both of these risk factors have very high prevalence in India, Nepal and other countries of this region. There is a synergistic interaction of tobacco smoking with hypertension and high blood cholesterol which greatly increase coronary heart disease risk as well as sudden death and stroke.
