【摘要】 目的　回顾应用冠状动脉旁路移植术 (coronaryarterybypassgrafting ,CABG)治疗冠心病的早期疗效和经验。方法　 116例冠心病患者中 ,97%为多支冠状动脉病变。男性 10 2例 ,女性 14例 ,年龄 3 5～ 80岁 ,平均年龄 67 4岁。 63例左室射血分数≤ 4 5 % ,19例 <3 0 %。 63 %患者的心绞痛CCS分级为III～IV级。 1例行左前外侧小切口非体外循环下手术 ,余均为正中开胸低温体外循环下行CABG ,2 3例采用左侧乳内动脉与左前降支搭桥 ,余均为大隐静脉桥。术后 2例需主动脉球囊反搏(IABP)支持。人均旁路移植血管 3 1支。结果　连续 116例患者手术临床效果良好 ,无一例手术死亡 ,术后 94 %的患者心绞痛完全消失。结论　本组患者的近期临床效果表明CABG是治疗冠心病的一种安全和有效的方法。更多还原

【Abstract】 Objective To retrospectively review the experience and early clinical results of coronary artery bypass grafting (CABG) for the treatment of coronary artery disease (CAD). Methods We have performed CABG on 116 consecutive patients (male 102, female 14), aged from 35 to 80 years with a mean of 67 4 years. 97% of them have multiple coronary artery disease. Left ventricular ejection fraction (EF) was equal to or lower than 45% in 63 patients and in 19 patients EF was less than 30%. 63% patients had class III or IV preoperative angina. All patients received CABG with middle sternotomy under the support of cardiopulmonary bypass (CPB) except one who received minimally invasive direct coronary bypass (MIDCAB) without CPB. The mean number of grafts was 3 1 and the internal mammary arteries (IMA) were used in 23 patients along with the saphenous veins. Postoperative intraaortic balloon pump (IABP) was required in 2 cases.Results Postoperative mortality was 0/116. All patients recorverd and discharged with 94% patients being angina free and 6 0% patients in class I angina at a mean follow up period of 24 9 months. Conclusion The good short term results in this small group indicate that CABG is a safe and effective way for the treatment of CAD with acceptable morbidity and mortality.更多还原
