우위대망동맥을 이용한 관상동맥우회수술

Abstract

BACKGROUND: The right gastroepiploic artery(RGEA) has been use in coronary artery bypass grafting from 1987. The RGEA is the most useful arterial conduit in coronary artery bypass grafting(CABG) followed by the internal mammary artery, MATERIALS AND METHOD: From Septermber 1998 to February 1999 the RGEA was used for coronary artery bypass grafting in 11 patients 10 males and 1 female. Postoperative angiography was performed in all of the patients before discharge RESULT: Early patent rate of the RGEA was 100%. The flow competition of the REGA graft was seen in 4 patients(36.4%) The flow pattern war RGEA dependent type in the inner diameter of the recipient coronary artery 1.5 mm the inner diameter of the RGEA 2.5 mm and the rtio of inner diameter of the RGEA and the recipient coronary artery 1(p<0.05) CONCLUSION: Early results of CABG with RGEA was satisfactory. However the RGEA graft has a tendency of flow competition in relation to the inner diameter of graft. Preoperative angiographic evaluation for RGEA and meticulous operative technique are required for a good surgical results.
