超声在出生缺陷产前诊断中的临床价值

目的探讨超声在产前诊断胎儿缺陷的临床价值。方法对8089例孕13～40周的妇女采用实时彩色多普勒超声仪进行系统检查，对胎儿畸形进行筛查和诊断，随访至产后7d。结果在8089例孕妇中，共发现先天性缺陷164例，超声诊断胎儿畸形104例，与产后诊断符合率为100％。超声检查漏诊60例，漏诊病例主要表现为较小畸形和缺陷。结论妊娠中晚期进行系统超声检查可以对胎儿形态结构方面的明显畸形进行产前诊断，对于降低出生缺陷发生率，提高人口素质具有重要意义。

Clinical Significance of Prenatal Ultrasonography for Detecting Birth Defects

Objective To explore the clinical significance of prenatal ultrasonography for detecting birth defects. Methods A total of 8089 women during 13-40 gestational weeks underwent real-time color Doppler ultrasonography to find out fetal congenital anomalies. All the cases were tracked within seven days after delivery. Results In all 8089 pregnant women, 164 cases with fetal defects were found and 104 cases were diagnosed fetal congenital anomalies on ultrasonography of 100% accordance with clinical diagnosis. Another 60 cases who had micro-malformation were misdiagnosed on color Doppler ultrasonography. Conclusions A systemic prenatal ultrasonographic examination in the second-trimester pregnancy is important for prenatal diagnosis of congenital malformations, which plays a very significant role in decreasing fetal birth defects and improving new born population quality.
