产前超声心动图诊断胎儿房室间隔缺损分型及合并畸形

目的 探讨胎儿超声心动图在诊断房室间隔缺损(AVSD)的常见类型、合并畸形中的作用及其要点。方法 选择胎儿超声心动图检查确诊的先天性心脏病312胎,其中AVSD 19胎,采用超声心动图对胎儿进行全面、系统、多切面扫查。结果 19胎AVSD中,完全型15胎,过渡型2胎,部分型2胎;其中13胎合并其他心脏畸形(6胎合并永存动脉干)。19胎全部引产,病理解剖证实12胎。结论 胎儿AVSD合并其他心脏畸形的发生率较高;分型以完全型AVSD最多;合并畸形中永存动脉干常见。

Prenatal echocardiographic diagnosis of types and accompanied malformations of fetal atrioventricular septal defects

Objective To explore the value of echocardiography in diagnosis the types and complicated malformations of fetal atrioventricular septal defects (AVSD), and to discuss the tips for diagnosing fetal AVSD. Methods Nineteen of 312 fetuses were diagnosed as AVSD with prenatal ultrasound. Fetuses were examined by echocardiography with a comprehensive, systematic, multi-slice scanning. Results In 19 fetuses, 15 were complete AVSD, 2 were transitional AVSD and 2 were partial AVSD. Thirteen fetuses accompanied with other abnormalities (6 fetuses with persistent truncus arteriosus). Labor induction was performed for 19 fetuses with AVSD, 12 AVSD were confirmed by autopsy. Conclusion Accompanied abnormalities are often found in AVSD fetuses;the complete AVSD is the most type in all of them;and persisient truncus arteriosus is the common type of complicated malformations.
