摘要
目的 探讨彩色多普勒超声心动图对胎儿动脉导管早闭的诊断价值。方法 应用彩色多普勒超声对 2例胎儿动脉导管早闭、1例导管收缩进行观察 ,并结合文献总结其胎儿超声心动图表现。结果超声心动图显示胎儿右心房、右心室扩大以及严重的三尖瓣反流等 ,及时分娩后右心功能迅速恢复。结论胎儿超声心动图在胎儿动脉导管早闭的诊断中具有重要作用。
Objective To study the value of echocardiography in diagnosis of prenatal closure of fetal ductus arteriosus(FDA) and discuss its characteristics. Methods Two cases with prenatal closure and one case with constriction of the FDA were examined.The echocardiographic characteristics were analyzed and the literature was reviewed. Results Right atrial and ventricular dilatation and severe tricuspid valve insufficiency were observed. After timely delivery, impaired right ventricular function improved significantly. Conclusions Fetal echocardiography plays an important role in diagnosis of prenatal closure of the FDA.
