摘要 目的总结成人小主动脉瓣环行心瓣膜置换术的临床经验,以提高手术效果。方法对26例成人小主动脉瓣环患者行人工机械瓣膜置换术,单纯主动脉瓣置换17例,二尖瓣、主动脉瓣双瓣膜置换9例。采用Manougnian法主动脉瓣环加宽7例,瓣膜侧倾缝合置换主动脉瓣膜6例,瓣环上主动脉瓣置换13例,在双瓣膜置换中均先置换主动脉瓣后再置换二尖瓣。结果26例患者中无手术死亡,术后随访时间6~48个月(12±3个月),心功能均明显改善(级10例、级16例),无远期死亡。术后主动脉瓣有效瓣口面积指数(EOAI)1.02~1.44cm2/m2(>0.85cm2/m2),无瓣膜-患者不匹配现象(PPM)。结论主动脉瓣病变伴小主动脉瓣环的成人患者行心瓣膜置换,选择新型人工瓣膜行瓣环上主动脉瓣置换是理想的选择,瓣膜侧倾缝合是可选择的方法,二尖瓣、主动脉瓣双瓣膜置换时先置换主动脉瓣可降低手术操作难度,大部分患者无需行瓣环扩大术。
