目的 总结分析非体外循环冠状动脉旁路移植术(OPCAB)中转为体外循环冠状动脉旁路移植术(on pump CABG)的原因及临床资料,以提高OPCAB的成功率。方法 8例患者中转为on pump CABG的原因为:2例术中发现心肌桥,处理时出血难以控制;6例凶术中严重的低血压,其中3例是在搬动心脏时,另外3例在切开靶血管时。中转患者中2例在心脏不停跳下完成,其他均在低温体外循环下完成,体外循环时间为101.8±8.5min。结果8例中转患者中无住院死亡;1例发生轻度的中枢神经系统并发症,其他患者无严重并发症发生;1例中转后术中用主动脉内球囊反搏(IABP)辅助完成手术。OPCAB患者与中转on pump CABG患者比较左心室舒张期末压(13.5±4.5mmHg vs.19.1±6.7mmHg)差别有统计学意义(t=2.180,P=0.04)。结论 左心室舒张期末压增高是OPCAB的高危风险因素,如果〉20mmHg应首选on pump CABG;急诊手术、心肌桥亦是OPCAB的风险因素。

Objective\ To test whether off pump coronary artery bypass grafting(OPCAB) has advantages over conventional coronary artery bypass grafting(CCABG).\ Methods\ Between January 1999 and February 2000, 170 patients with multivessel coronary disease underwent only coronary artery bypass grafting by one surgeon. They were divided into two groups, OPCAB group:88 cases underwent CABG with off pump and beating heart via sternotomy; CCABG group: 82 cases underwent conventional CABG with extracorporeal circulation....
