冠状动脉搭桥术治疗冠心病临床分析

Clinical study on coronary artery bypass grafting in the treatment of coronary artery disease

目的 :探讨冠状动脉搭桥术 (CABG)治疗冠心病的早期效果和经验。方法 :2 6例冠心病患者接受CABG ,术前心绞痛 (CCS)Ⅰ级 2例 ,Ⅱ级 7例 ,Ⅲ级 13例 ,Ⅳ级 4例。 2 4例浅低温体外循环下行CABG ,2例非体外循环下施术。除 1例左乳内动脉 (LIMA)纤细血流不足改用大隐静脉外 ,2 5例采用LIMA与前降支搭桥 ,人均搭桥 3.2支。结果 :2 5例术后随访 6～ 30个月 ,2 4例心绞痛症状完全消失 ,1例心绞痛Ⅰ～Ⅱ级。低心排术后死亡 1例。结论 :CABG治疗冠心病疗效确切 。

Aim: To study the experience and early results of coronary artery bypass grafting (CABG) in the treatment of coronary artery disease. Methods: CABG was performed on 26 consecutive patients, and preoperative angina(CCS) class Ⅰ was 2,class Ⅱ 7,class Ⅲ 13,class Ⅳ 4. A total of 24 patients received CABG through middle sternotomy under cardiopulmonary bypass (CPB), 2 received CABG without CPB. The left internal mammary artery was used in 25 patients ,and the average number of grafts was 3.2 .Results: 24 patients are angina free and 1 in class Ⅰ～Ⅱ angina at a follow up period of 6～30 months.One patient died from low cardiac output. Conclusion: CABG is safe and effective for the treatment of coronary artery disease. Complete revascularization ischemic myocardium and perioperative treatment are the key of CABG.
