[Quadruple coronary artery bypass grafting with arterial grafts--application of internal thoracic artery and right gastroepiploic artery].

Arterial graft has been widely applied for coronary artery bypass because of its excellent long-term patency. However, when more than four coronary bypass graftings should be carried out using internal thoracic arteries (ITAs) and right gastroepiploic artery (GEA), some surgical techniques must be devised. We performed quadruple coronary artery bypass grafting using three arterial grafts; bilateral ITAs and GEA, and obtained good results. We used free RITA graft for sequential grafting in one case. In another case, GEA was divided into two segments and used as two free grafts. From our experience, we believe it is possible to perform multiple coronary revascularization using only arterial grafts with one median skin incision.
