孕中期胎儿致死性先天性心脏病超声筛查

Ultrasound screening for fetal congenital heart disease in the second trimester of pregnancy

目的:探讨超声诊断孕中期胎儿致死性先天性心脏病的临床价值。方法:选择2014年1月—2016年12月进行经产前胎儿先天性心血管疾病超声筛查孕妇3 027例,采用四腔心切面、流出道切面及彩色多普勒超声心动图三种检查方法,分析确诊为先天性心脏病的资料。结果:3 027例孕妇中42例胎儿心脏异常,检出率为1.39%,四腔心切面、流出道切面及彩色多普勒超声心动图三种检查方法的敏感度分别为71.43%、85.71%及95.24%,特异度为96.7%、98.2%及99.7%。结论:彩色多普勒超声诊断孕中期胎儿致死性先天性心脏病具有重要的临床应用价值,与传统超声检查相比,彩色多普勒超声能够较准确地判断先天性心脏病,且安全、准确、简便,对诊断胎儿致死性先天性心脏病意义重大,是产前排除胎儿致死性先天性心脏病的首选方法。

Objective： To investigate the clinical value of ultrasonogra-phy in the diagnosis of fetal congenital heart disease in the second trimester of pregnancy. Methods： From January 2015 to December 2016 after prenatal ultrasound screening for fetal congenital cardiovascular disease in 3 027 pregnant women,the four chamber view,outflow tract views and color Doppler echocardiography in 3 methods of inspection,analysis of diagnosis of congenital heart disease data. Results： All 3 027 pregnant women with abnormal fetal heart rate of 42,the detection rate was 1. 39%. The sensitivity of the 3 methods of the four chamber view,outflow tract section and color Doppler echocardiography were 71. 43%,85. 71%,95. 24%,specificity were 96.7%,98. 2%,99. 7%. Conclusion： Color doppler ultrasound in the diagnosis of fetus died of congenital heart disease has important clinical application value,compared with conventional ultrasonography,color doppler ultrasound can accurately judge the congenital heart disease,and the advantages of this method is safe,accurate and convenient for the diagnosis of fetal death,congenital heart disease of great significance,is the preferred method of prenatal fetal death to exclude congenital heart disease.
