目的 探讨应用国产动脉导管未闭(PDA)封堵器关闭呈管型的膜部室间隔缺损(VSD)的临床效果及安全性.方法 我院膜部VSD患者20例,经心脏彩超及造影证实为管型膜部VSD,采用国产PDA封堵器进行关闭.在X线影像及彩超的监测下建立动静脉轨道,经静脉系统释放封堵器,术后1、6、12个月进行心脏彩超及心电图检查.观察VSD有无残余分流,有无主动脉瓣、三尖瓣反流,有无房室及/或束支传导阻滞.结果 20例VSD病例全部封堵成功,无主动脉瓣及三尖瓣反流,无房室及束支传导阻滞发生,无封堵器脱落及移位,无右室流出道狭窄.1、6、12个月心脏彩超提示封堵器位置正常,无瓣膜反流,心电图正常.结论 应用国产PDA封堵器关闭呈管型的膜部VSD安全、可靠.
