序贯式主动脉-冠状动脉搭桥术(附171例报告)

SEQUENTIAL AORTO-CORONARY BYPASS GRAFTS IN 171 PATIENTS

本文报告了171例冠状动脉搭桥术。年龄41～77岁。其中三支血管病变占62.6％。一条静脉搭2～7支桥,人均搭桥4.0支。术后早期死亡率1.2％。文中着重介绍了大隐静脉序贯式主动脉-冠状动脉搭桥术的技术特点。

One hundred and seventy one patients with sequential aorto-coronary bypass grafts performed from Jan. 1985 to Dec. 1988 by the first author are presented. The patients age ranged from 41 to 77. Among them 129 patients had unstable angina pectoris and 42 patients had chronic stable angina pectoris. 107 patients (62.6％) had three-vessel disease, 53 patients (31.0％) had two-vessel disease, 11 patients (6.4％) had one-vessel disease. Number of distal anastomosis on one piece of the vein ranged from 2 to 7. Each patient had 4.0 distal anastomoses in average. Hospital mortality rate was 1.2％. In this series three basic types of sequential grafts were performed. Ⅰ. a sequential graft was on LADD system; Ⅱ. a sequential graft was on CX-RCA system, and Ⅲ a sequential graft was on LAD-CX-RCA system. The technical features of our saphenous vein sequential aorto-coronary bypass grafts are presented in detail.
