目的:探讨彩超对胎儿复杂先天性心脏病的诊断价值。方法:20孕周以上孕妇6 500例,应用彩色多普勒超声检查胎儿心脏四腔心、左室流出道、右室流出道等切面,观察胎儿心脏结构及血流有无异常。结果:共查出有典型声像图表现的复杂先心病20例,生后复查或引产后解剖证实。结论:超声检查能够发现多种类型的胎儿复杂先天性心脏异常,是产前诊断的重要方法。
Objective: To investigate the diagnostic value of color Doppler ultrasonography in fetal complicated congenital heart disease. Methods: 6 500 pregnant women with gestational age above 20 gestational weeks were enrolled in this study. Fetal heart four chambers, left ventricular outflow tract and right ventricular outflow tract were examined by color Doppler ultrasonography to observe the fetal heart structure and blood flow. Results: A total of 20 cases of complex congenital heart disease with typical sonographic findings were confirmed, and confirmed by postnatal follow-up or post-abortion anatomy. Conclusion: Ultrasonography can detect multiple types of fetal congenital heart abnormalities and is an important method of prenatal diagnosis.
