【摘要】 目的　总结分析非体外循环冠状动脉旁路移植术 (OPCAB)的早期临床结果和经验体会。方法　 1996年 10月至 2 0 0 2年 5月在国内 15个冠心病微创外科中心完成非体外循环冠状动脉旁路移植术 1198例 ,占同期冠心病手术的 79 5 % ,OPCAB实施率 (即OPCAB占单纯冠状动脉旁路移植术的百分比 )为 85 2 %。年龄平均 (6 1 6± 9 0 )岁 ,男性占 77 3%。 18 7%为左主干病变 ,76 9%为 3支病变。左心室射血分数平均 0 5 6± 0 17。其中二次手术者占 1 5 % ,急诊手术占 9 9%。结果　 2 2例为小切口单支病变旁路移植手术 ,其余均为正中切口、多支病变的OPCAB手术。远端吻合口为 (3 1± 0 9)个 ,乳内动脉桥占 6 5 6 % ,桡动脉桥占 18 0 % ;5 2 %病人使用主动脉内球囊反搏。住院死亡 14例 ,病死率 1 2 %。其中术后心跳骤停或室颤 7例 ,大出血 2例 ,昏迷伴肾功能衰竭 2例 ,大面积脑梗塞 2例 ,呼吸衰竭 1例。并发症中 ,围术期心肌梗死占 0 4% ,急性左心功能衰竭占 0 3% ,严重心律失常占 1 2 % ,呼吸系统并发症占 2 0 % ,器质性神经系统并发症占 1 2 % ,新发或加重的肾功能不全占 0 7% ,出血二次开胸占1 0 % ,胸骨愈合不良占 0 6 %。结论　OPCAB手术安全可行 ,早期效果满意 ,远期效果有待进一步观察。OPCAB具备一?更多还原

【Abstract】 Objective: To summarize and analyze the early outcomes and clinical experience in 1198 patients undergone off-pump coronary artery bypass (OPCAB). Methods: This multi-center report covers 15 different institutes in China from October 1996 to May 2002. The ratio of OPCAB to conventional coronary artery bypass grafting (cCABG) was 85.2%. The mean age was (61.6±9.0) years. 77.3% patients were male and 22.7% were female. There were 34.6% patients with myocardial infarction, 58.2% with unstable angina pectoris, 18.7% with left main lesion, 76.9% with triple-vessel disease, 1.5% was redo surgery, and 9.9% emergent or urgent surgery. The mean left ventricular ejection fraction was 0.56±0.17. Results: The number of distal anastomosis was 3.1±0.9. IMA was used in 65.6% patients and radial artery was used in 18.0%. 13.5% OPCAB was combined with TMLR. IABP was used in 5.2% patients. The hospital mortality was 1.2%. The morbidity included 0.4% peri-operative myocardial infarction, 0.3% heart failure, 1.2% fatal arrhythmia, 2.0% pulmonary complications, 1.2% neurotic disorder, 0.7% renal dysfunction, 1.0% reopen for bleeding, and 0.6% delayed wound healing. Conclusion: OPCAB surgery is a safe and feasible procedure with good early results. Its late outcomes need further follow-up. OPCAB requires certain special skills and methods in practice so a specific training course should be designed.更多还原
