彩色多普勒超声心动图诊断胎儿先天性心脏病的临床价值

目的:探讨彩色多普勒超声技术在诊断胎儿心脏异常中的应用价值。方法:对临床高度疑有胎儿先天性心脏病(CHD)的孕妇2600例行胎儿超声心动图检查。结果:检出胎儿心脏异常20例,检出率0.77%。其中CHD17例(0.65%),心脏肿瘤1例(0.038%),三尖瓣中量反流1例(0.038%),心包少量积液1例(0.038%)。经引产尸体解剖证实11例,产后彩色多普勒超声检查证实7例,失访2例。结论:胎儿超声心动图检查对产前检出胎儿心脏病具有重要的临床价值;胎儿心胸或心腔比率异常及胎儿心脏四腔观异常是胎儿CHD的最主要声像图表现。

Clinical Value of Color Doppler Echocardiography in Diagnosing Abnormality of Fetal Heart

Objective:To assess the value of echocardiography in diagnosing abnormality of fetal heart,especially of fetal congenital heart disease(CHD).Methods: The study included 2600 pregnant women who were at high risk of CHD. All fetuses were examined using color Doppler echocardiography.Results: Twenty cases of fetal cardiovascular abnormality were found, with the abnormality rate of 0.77%. Seventeen cases were CHD,with the detection rate of 0.64%. One was heart tumor, one moderate regurgitation of tricuspid valve and one mild pericardial effusion. Among these cases,11 were confirmed by autopsy, 7 were compared with postnatal echocardiography, 2 were lost to follow up.Conclusion: Echocardiography is of great value for prenatal diagnosis of fetal CHD. The abnormalities of the cardiothoracic ratio, heart chamber ratio and four-chamber vision are most important images of fetal CHD.
