产前超声筛查胎儿先天性心脏病的临床价值分析

目的探讨胎儿超声心动图(FECG)产前筛查胎儿先天性心脏病(CHD)的临床应用价值。方法采用四腔心、左室流出道、右室流出道、三血管切面四切面法,对6 500例孕20～41周孕妇进行产前FECG筛查,以引产后尸解或产后新生儿ECG作为对照标准。结果 6 500例胎儿中,检出胎儿心脏异常69例,包括复杂性先天心脏病部分合并心外畸形39例。结论四切面检查方法简便可靠,是显示胎儿心脏结构及产前筛查胎儿CHD的重要影像诊断方法。

Analysis on clinical value of prenatal ultrasonography in screening of fetal congenital heart disease

Objective To analyze the clinical application value of fetal echocardiography(FECG) in screening of fetal congenital heart disease(CHD). Methods Prenatal fetal echocardiography screening were performed in 6500 pregnant women(at 20～41 weeks of gestation) by four chamber view,left ventricular outflow tract,right ventricular outflow tract and three vessels methods.The result of fetus autopsy from induced abortion or neonatal echocardiography was the control criterion. Results In all 6500 fetus,69 cases of cardiac abnormalities were confirmed by screening,including 39 cases of complex congenital heart diseases,partial cases combined with extracardiac abnormality. Conclusion The four chamber view is a simple and effective method to detect the fetal cardiac structure which has important imaging diagnostic value for prenatal fetal congenital heart disease screening.
