超声产前诊断胎儿畸形

Prenatal diagnosis with ultrasonography for fetal congenital anomaly

目的探讨超声在产前诊断胎儿畸形的临床价值。方法采用彩色多普勒超声诊断仪对2230例孕11～40周的孕妇进行系统超声检查并随访。结果2230例孕妇中，超声诊断胎儿畸形28例，漏诊8例。发生畸形位居前三的是心血管畸形，神经管畸形。泌尿系统畸形。漏诊病例多为心血管畸形及较小畸形。结论超声检查可以对胎儿形态结卞句方面的明显畸形作出明确的产前诊断，明显减少出生缺陷，提高人口素质。对于心血管畸形及较小畸形还有待于改进方法，加强规范操作。

Objective To explore the clinical significance of the prenatal ultrasonography for fetal congenital anomaly. Methods A total of 2230 pregnant women during 11--40 weeks underwent color Doppler to find out fetal congenital anomalies, and all the eases were tracked. Results In all 2230 pregnant women, 28 eases with fetal congenital anomaly were found, among them cardiovascular system malformation, nervous system malformation and urinary system malformation were the most common anomalies. The fetal congenital anomalies of 8 cases were misdiagnosed, the most of them were car diovascular system deformities and micro-malformation. Conclusion Ultrasonography can conclusively diagnose fetal congenital anomaly in morphology, effectively diminish the rate of birth defects, and improve new born population qulity. However, the method of ultrasonography for micro-malformation and cardiovascular system malformation should be promo ted, and the operation should be standardized.
