Intermediate Clinical Results of Combined Gastroepiploic and Internal Thoracic Artery Bypass

Second Department of Surgery, Kurume University School of Medicine, Fukuoka, Japan

Accepted for publication June 18, 1996.

Background. To improve the postoperative results of coronary artery bypass grafting (CABG), the internal thoracic artery (ITA) has become the conduit of choice, with a low operative risk. The gastroepiploic artery as a third arterial conduit for grafting was first reported in 1987, and the early results were reported to be as good as those for the ITA graft. In this report, we present the intermediate-term results of combining ITA and gastroepiploic artery grafts up to 7 years after the operation.

Methods. Between April 1988 and April 1992, 214 patients received CABG with at least one ITA graft and were followed up for more than 3 years. They were divided into two groups: Group I consisted of 155 patients who had CABG using one ITA with or without saphenous vein grafts, and group II consisted of 59 patients who had CABG using an ITA and a gastroepiploic artery with or without saphenous vein grafts. The duration of follow-up for hospital survivors ranged from 36 to 89 months.

Results. There were six late cardiac deaths in group I and one in group II. Fifteen patients complained of recurrent symptoms of angina: 13 in group I and 2 in group II. The actuarial survival rate excluding noncardiac deaths was 95.9% in group I and 96.8% in group II at 7 years (p = not significant). The cardiac event-free rate was 75.4% in group I and 92.2% in group II, which was a significant difference (p < 0.05).

Conclusions. When using both the ITA and gastroepiploic artery, CABG can be performed with minimal operative risk and seems to offer an improved quality of life at least 7 years postoperatively.
