彩色多普勒超声心动图在室间隔缺损封堵术中的应用

目的评价彩色多普勒超声心动图对室间隔缺损(VSD)的定位及大小测量的准确性和在封堵术术前、术中及术后的应用价值。方法应用彩色多普勒血流显像(CDFI)在封堵术前选择适应证;术中监视封堵器释放过程,观察室间隔缺损处的封堵疗效及周边有无残余分流,对封堵效果进行随访。结果在彩色多普勒超声心动图指导下进行封堵的21例患者均全部封堵成功,封堵器置入后即刻听诊,杂音减轻或消失,超声检查无残余分流,无主动脉瓣和三尖瓣返流,同时经心血管造影证实无残余分流和主动脉瓣返流。结论彩色多普勒超声在VSD封堵术中的应用具有重要的临床价值,对术前选择适应证,术中监视封堵器释放过程,术后判断封堵术疗效及随访都有重要的指导意义。

Application of color Doppler echocardiography in ventricular septal defect occlusion

Objective To evaluate the values of color Doppler echocardiography in ventricular septal defect(VSD) of the location and size the accuracy and the closure preoperative,intraoperative and postoperative.Methods Color Doppler flow imaging(CDFI) in the closure of preoperative selection indication;Intraoperative monitoring occluder release process was observed at the ventricular septal defect closure without residual shunt and peripheral effects of closure blocking were followed up.Results Color Doppler echocard...
