【摘要】 目的 :探讨超声筛查胎儿先天性心脏畸形的可行性及应用价值。材料和方法 :对 5 0 0 0例产前超声检查者常规观察胎儿心脏四个切面 ,即四腔心、左室流出道、右室流出道、三血管平面 ,疑有异常者行超声心动图检查。结果 :超声检查发现 2 5例先天性心脏畸形 ,其中 2 2例引产尸解证实 ,3例出生后超声心动图复查证实。漏诊室间隔缺损 3例 ,房间隔缺损 3例。结论 :胎儿心脏四个切面筛查能发现绝大部分先天性心脏畸形 ,包括大血管畸形 ,但易漏诊小的室间隔缺损及房间隔缺损。更多还原

【Abstract】 Purpose: To evaluate the feasibility of prenatal ultrasound examination of fetal congenital heart anomalies. Materials and Methods: A total of 5000 prenatal ultrasound studies was analyzed retrospectively in this study. The ultrasound study was carried out in 4 views, i.e. 4-chamber, left outflow tract, right outflow tract, and 3-vessels views. Detailed fetal echocardiography was undertaken if any abnormality suspected in the screening test. Results: A total of 25 fetuses were found to have cardiovascular malformation. Of them, 22 had abortion, and the autopsy confirmed the ultrasound findings. The diagnosis in the rest 3 cases was confirmed by postnatal echocardiography. Prenatal ultrasound missed 3 VSD and 3 ASD. Conclusions: Most of the congenital heart diseases can be detected by antenatal ultrasound, but smaller VSD and ASD are still difficult to diagnose prenatally.更多还原
