胎儿超声心动图诊断胎儿先心病在高危妊娠产前筛查中的意义

目的探讨胎儿超声心动图在高危妊娠产前筛查中的意义。方法应用西门子SonolineG60S型彩色多普勒超声诊断仪对570例孕龄在22-40周的高危妊娠孕妇行胎儿超声心动图检查,并将产前超声检查与胎儿尸检或分娩后超声心动图检查结果进行对照。同时检测孕龄在22-40周无明显高危妊娠因素的孕妇750例,作为平行对照组。结果检出72例心脏异常,先天性心脏畸形47例,先心病检出率为3.56%,其中高危组41例,先心病检出率为7.2%;对照组6例,检出率为0.8%。另外发现左室腔内强回声8例,心包积液3例,三尖瓣少量反流14例。结论超声心动图常规及系统诊断技术是诊断胎儿先天性心脏病较完善、可靠的方法,对检测胎儿心脏畸形有着十分重要的临床应用价值,对高危妊娠孕妇更应及早行常规胎儿心脏超声心动图检查胎儿。单纯性心包积液或单纯性少量三尖瓣反流或单纯心脏内有点状强回声,不能作为终止妊娠的指标。

The significance of fetal echocardiography in diagnosis on fetal congenital heart disease in high-risk pregnancy in the of prenatal screening

Objective:To study the significance of fetal echocardiography in high-risk pregnancy in the of prenatal screening.Methods:570 cases of gestational age between 22 and 40 weeks in high-risk pregnancy are detected in fetal echocardiography by Siemens Sonoline G60S diagnostic color Doppler ultrasound,and the results of prenatal ultrasound and fetal autopsy and echocardiography after delivery are compared.At the same time,as a parallel control group,750 cases of pregnant women of gestational age in the 22 -40 we...
