title: Coronary artery bypass grafting by utilizing in situ right gastroepiploic artery: basic study and clinical application.
abstract: The right gastroepiploic artery (GEA) was studied angiographically and histologically to determine its suitability for coronary artery bypass grafting. One hundred celiac angiograms demonstrated that the right GEA has the appropriate size (diameter less than 1.5 mm, 4%; 1.5 to 2 mm, 29%; more than 2 mm, 67%) and length (less than half of the greater curvature, 5%; more than half of the greater curvature, 95%; more than two-thirds of the greater curvature, 34%) for use as an in situ graft. A stenotic lesion of a GEA was observed in only 1 angiogram. Histological examination of a right GEA from 5 patients who had undergone gastrectomy demonstrated no evidence of arteriosclerosis. Encouraged by these results, we performed a coronary artery bypass reoperation utilizing an in situ right GEA graft in 2 women. Postoperative angiograms showed good patency of those grafts. The patients recovered well and were free from angina.
