摘要 目的总结主动脉瓣环加宽后的主动脉瓣置换术治疗小主动脉瓣环合并主动脉瓣病变患者的临床经验。方法对41例小主动脉瓣环合并主动脉瓣病变患者(瓣环直径为15-21mm)行主动脉瓣环加宽后的主动脉瓣置换术,主动脉瓣环加宽采用改良Nicks法ll例,改良Manougnian法29例,Konno法1例。结果41例患者主动脉瓣环加宽后都可以植入比测量的主动脉瓣环直径大1#或2#的主动脉瓣,无手术死亡。术后所有患者随访4~36个月(13±2个月),无死亡、瓣周漏、二尖瓣反流和主动脉扩张;超声心动图检查示:人工瓣跨瓣峰值压差为9~25mmHg(17±6mmHg),与术前的70-105mmHg(80±15mmHg)比较差别有统计学意义(P〈0.01)。结论小主动脉瓣环合并主动脉瓣病变患者,在置换主动脉瓣时先行主动脉瓣环加宽,能使患者在术后获得良好的血流动力学效果,是一种安全、有效的手术术式。
