目的探讨超声在产前诊断胎儿缺陷的临床价值。方法对4927例孕16~40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。结果在4927例孕妇中,共发现先天性缺陷58例,产前共诊断出48例胎儿畸形,漏诊10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。
Objective To investigate the clinical value of ultrasound in prenatal diagnosis of fetal defects. Methods 4927 women aged 16 ~ 40weeks were systematically inspected by real-time color Doppler ultrasound, and the fetal malformations were screened and diagnosed. Results In 4927 pregnant women, 58 cases of congenital defects were found. Prenatal diagnosis of 48 cases of fetal malformations, missed diagnosis of 10 cases. Misdiagnosed cases are mainly minor deformities and defects. Conclusions Systematic ultrasonography in the second trimester of pregnancy can make prenatal diagnosis of obvious deformities in fetal morphology and structure, which is of great significance for reducing the incidence of birth defects and improving the population quality.
