The internal mammary artery is widely recognized as the graft of choice for coronary artery bypass grafting at present. Alternative conduits have been investigated in order to find other adequate long-term grafts. The right gastroepiploic artery has been recently used as a graft to bypass distal coronary vessels. From November 1989 to June 1990, we have implanted this artery in 46 cases. Pedicled grafts were implanted in 20 patients to the main right coronary artery, in 21 patients we grafted the right distal branches, in 3 patients the left anterior descending, and in 2 the circumflex branches. Mean grafts per patient were 3 in this series, with a mean of 2.2 arterial grafts per patient. One patient died in the early postoperative period. The remaining patients had an uncomplicated postoperative evolution. Thirteen patients underwent graft and coronary angiography. Direct or indirect graft patency was confirmed in all cases. The final important issue concerning the long-term patency of this graft will be solved in the future, but short-term patency rates of the right gastroepiploic artery can be anticipated when proper techniques are used.
目前，乳内动脉被广泛认为是冠状动脉旁路移植术的首选移植物。人们一直在研究替代血管，以寻找其他合适的长期移植物。近来，胃网膜右动脉已被用作绕过冠状动脉远端血管的移植物。从1989年11月至1990年6月，我们将此动脉植入46例患者体内。带蒂移植物植入20例患者的右冠状动脉主干，21例患者的右冠状动脉远端分支，3例患者的左前降支，2例患者的回旋支。本系列患者平均每人植入移植物3个，平均每人植入动脉移植物2.2个。1例患者术后早期死亡。其余患者术后恢复顺利。13例患者接受了移植物和冠状动脉造影。所有病例均证实移植物直接或间接通畅。关于该移植物长期通畅性的最终重要问题将在未来得到解决，但采用适当技术时，可预期胃网膜右动脉的短期通畅率。
