主动脉瓣置换术105例临床分析

Clinical Analysis of Aortic Valve Replacement in 105 Cases

目的 :总结 10 5例主动脉瓣置换术的临床经验。方法 :自 1991年 1月至 2 0 0 0年 6月共行主动脉瓣机械瓣置换术 10 5例。结果 :体外循环时间 5 5～ 2 19分 (112± 30分 ) ,升主动脉阻断时间 30～ 15 0分 (6 4± 19分 ) ,手术时间 190～ 5 40分 (2 6 4± 6 3分 )。术后发生低心排血综合征 8例 (7 6 % ) ,严重室性心律失常 10例 (9 5 % )。死亡 8例 ,死亡率 7 6 %。结论 :如病例选择适当 ,主动脉瓣置换术安全可行且效果好 ,室性心律失常是术后最常见的并发症 ,也是术后死亡最常见的原因。

Objective:To review the clinical result and experiences of treatment from aortic valve replacement in 105 patients.Methods:The routine operation of aortic valve replacement in 105 patients were performed from Jan.1991 to Jun 2000.Results:The time of cardio-pulmonary bypass was 55-219 minutes(112±30min).The time of aortic cross-clamp was 30-150minutes(64±19min).Low output syndrome occurred in 8 patients(7 6%)and severe ventricular arrhythmia occurred after operation in 10 patients(9 5%).Eight patients died after operation with a mortality of 7 6%.Conclusions:Aortic valve replacement is safe and practical in selected patients.The most common complication is ventricular arrhythmia.
