摘　　要：目的：探讨超声在产前诊断胎儿畸形的临床价值。方法：对4718例13-40周的孕妇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的诊断，追踪随访至产后1周。结果：在4718例孕妇中，超声诊断胎儿畸形156例，与产后诊断符合率为100％。超声检查漏诊22例，漏诊病例主要表现为较小畸形。结论：妊娠中晚期进行系统超声检查可以产前诊断胎儿形态结构的明显畸形，对于降低出生畸形发生率，提高人口素质有重要意义。Objective： To explore the clinical significance of prenatal uhrasonography for detecting fetal anomalies. Methods： A total of 4718 women during 13-40 gestational weeks underwent real -time color Doppler uhrasonography to find out fetal congenital anomalies. All the cases were tracked within a week after delivery. Results： In all 4718 pregnant women , 156cases were diagnosed fetal congenital anomalies on uhrasonography of 100% accordance with clinical diagnosis. Another 22 cases who had micro - malformation were misdiagnosed on color Doppler uhrasonography. 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 anomalies and improving new born population quality.
