Surgical Treatment of Coronary Artery Occlusive Disease

관상동맥협착증의 외과적 치료 -6례 보고-

Between July, 1987, and September, 1988, 6 patients with coronary occlusive disease received coronary artery bypass surgery at Kyungpook University Hospital. There were five males and one female whose age ranged from 39 to 64 years[mean 54*8.0 years]. Of the 6 patients, 5 suffered from unstable angina, 1 suffered from stable angina. Selective coronary angiography revealed a significant stenosis of the left anterior descending artery in 6 cases, of its diagonal branch in 1 case, of the right coronary artery in 1 case, the circumflex artery in 1 case, and of its obtuse marginal branch in 1 case. The mode of anastomosis were single saphenous vein graft in 3 cases, single left internal mammary artery graft in 1 case, double saphenous vein graft with sequential anastomosis in 1 case, and left internal mammary artery plus saphenous vein graft in 1 case. Of these, 6 grafts to left anterior descending artery were done. There was no operative death, but perioperative myocardial infarction was happened in 1 case. All survivors were free of angina and discontinuing medical therapy during the follow up period[mean 7.8*5.15 months].
