双血管桥在冠状动脉前降支多处局限性狭窄中的应用

目的探讨双血管桥在冠状动脉前降支多处局限性狭窄中的应用与疗效。方法回顾性分析106例冠状动脉前降支多处局限性狭窄外科治疗患者的临床资料。依手术方法不同分为两组，改良组56例，采用前降支搭双血管桥。对照组50例，采用搭单支血管桥至前降支狭窄段远端。结果两组年龄、性别构成、体质量指数、左心室射血分数、体外循环时间、气管插管时间、住院时间比较差异无统计学意义（P〉0．05）。改良组术后发生心绞痛1例、左心室大小为（51±6）mm、左心室射血分数为（60．8±8．0）％，对照组分别为9例、（43±6）mm、（55．1±10．0）％，两组比较差异有统计学意义（P〈0．05）。结论双血管桥在冠状动脉前降支多处局限性狭窄中应用安全、有效。

Double blood vessels bridge application in multiple localized narrow of the anterior descending coronary artery

Objective To explore the double blood vessels bridge application and efficacy in multiple localized narrow of the anterior descending coronary artery. Methods The clinical data of 106 patients with multiple localized narrow of the anterior descending coronary artery were retrospectively analyzed. The patients were divided into two groups according to the operation methods. Fifty-six patients （improvement group） were conducted double blood vessels bridge on the anterior descending coronary artery, 50 patients （control group） were conducted a single blood vessel bridge on the anterior descending coronary artery. Results The age, sex, body mass index,left ventricular ejection fraction, extracorporeal circulation time, endotracheal intubation time,length of hospital stay between two groups had no significant difference （P 〉 0.05）. One case in improvement group occurred angina pectoris, left ventricular size was （51 ± 6） mm, left ventricular ejection fraction was （60.8 ± 8.0）%. Nine cases in control group occurred angina pectoris, left ventricular size was（43± 6） mm, left ventricular ejection fraction was（55.1 ± 10.0）%. There was significant difference between two groups（P 〈 0.05）. Conclusion Double blood vessels bridge is safe and effective in multiple localized narrow of the anterior descending coronary artery.
