摘要 目的 :总结主动脉瓣环扩大术在小主动脉瓣环换瓣术中的应用经验。方法 :2009年2月~2014年1月我院收治小主动脉瓣环患者19例,采用Manouguian法、Nicks法扩大瓣环,再置入合适型号的机械瓣。同期行二尖瓣机械瓣置换并三尖瓣成形2例、左室流出道疏通1例。结果 :19例均痊愈出院,术后早期无严重并发症(低心排综合征、二次开胸止血、恶性心律失常)。术后随访6-36个月无死亡,心功能均Ⅰ-Ⅱ级,心脏彩超检查主动脉瓣跨瓣压差和瓣口流速均显著降低。其中一例Manouguian法扩大瓣环并置入18mm ATS AP瓣患者术后3个月时发生Ⅲ°房室传导阻滞,行永久起搏器置入后恢复出院。结论 :小主动脉瓣环患者在主动脉瓣置换时行瓣环扩大成形,能获得满意的近期效果,是一种安全有效的术式。瓣环扩大的关键在于严格把握指证、恰当选择术式。
