title: [Coronary revascularization with arterial graft alone].
abstract: In the period from December 1989 until July 1991, coronary revascularization were performed on 56 patients using arterial grafts and no venous grafts. The ages of the patients ranged from 43 to 85 years (average; 66.8 years), and there were 33 males and 23 females. Twenty-four patients had angina pectoris, 23 had old myocardial infarction and 9 had acute infarction. There were 3 patients with single-vessel coronary disease, 19 with double-vessel, 31 with triple-vessel and 9 with left main coronary disease. The bypass grafts used were 58 left internal thoracic artery (LITA) grafts, 29 right internal thoracic artery (RITA) grafts, and 56 right gastroepiploic artery (RGEA) grafts. Thus, 143 grafts were used and an average of 2.6 bypasses were created per patient. There were two operative deaths. One of these patients had acute myocardial infarct. Investigation of postoperative graft patency was performed in the 122 grafts that could be examined angiographically after surgery. Only 7 were obstructed, yielding a patency rate of 94.3%. By using both the ITA and RGEA, in situ anastomoses with all the coronary arteries could be performed. Also in emergency surgery arterial grafting was possible. This operative form is considered to be a useful technique and may be expected to produce favorable long-term results.
