Keyword:  超声心动图动脉导管未闭封堵术;
Abstract: 目的:探讨超声心动图在动脉导管未闭(PDA)封堵术疗效评价中的价值.方法:48例PDA患者经导管进行封堵术.在术前及术后1周分别进行超声心动图的检查,观察大动脉水平有无分流及心脏大小、功能的改变.结果:术后1周复查,肺动脉平均内径从32.1 mm缩小到25.3 mm,P<0.05;左室舒张末期平均内径从55.4 mm缩小到48.9 mm,P<0.001;左房平均内径从30.7 mm缩小到28.1 mm,P<0.01;左室射血分数虽然从64.4%下降到62.4%,但未见统计学差异,P>0.05.术后1周复查3例患者均存在少量残余分流,3个月后随访残余分流消失.结论:经导管介入治疗PDA是一种创伤小、疗效高的非开胸治疗先天性心脏病的方法,超声心动图对术前患者的筛选,术后检测有无残余分流,对心脏血流动力学评价及疗效的观察起了重要的作用.
