胎儿畸形的产前系统超声筛查结果回顾性分析

Retrospective analysis of prenatal systematic ultrasound screening results of fetal malformations

目的研究产前系统超声检查对胎儿畸形的诊断价值,分析畸形胎儿的特征分布情况及漏诊原因。方法回顾性分析2016年1月至2020年1月于重庆市垫江县人民医院超声科行产前系统超声检查的10017例孕妇的临床资料。采用彩色多普勒超声仪进行胎儿畸形诊断,分析胎儿畸形的特征分布情况、漏诊类型及结局。结果共检出胎儿畸形110例,畸形率为1.10%。其中,单发畸形95例,占比为86.36%,复合畸形15例,占比为13.64%。110例畸形儿经出生后、引产以及尸检或染色体检查证实。超声漏诊9例,漏诊率为7.56%。结论产前系统超声检查对胎儿畸形的检出率较高,可促进优生优育,临床意义重大。

Objective To study the diagnostic value of prenatal systematic ultrasound in fetal malformations,and to analyze the feature distribution of fetal malformations and the causes of missed diagnosis.Methods The clinical data of 10017 pregnant women who underwent prenatal systematic ultrasound in the ultrasound department of Dianjiang people's hospital of Chongqing from January 2016 to January 2020 were retrospectively analyzed.Color Doppler ultrasound equipment was used to diagnose fetal malformations.The feature distribution of fetal malformations,missed diagnosis types and outcomes were analyzed.Results A total of 110 fetal malformations were detected,and the abnormal rate was 1.10%.Among them,95 cases of single malformation,accounting for 86.36%,15 cases of complex malformation,accounting for 13.64%.The 110 cases were confirmed by postnatal,induced labor,autopsy or chromosome examination.Nine cases were missed by ultrasound,the missed diagnosis rate was 7.56%.Conclusion Prenatal systematic ultrasound examination has a higher detection rate of fetal malformation,which can promote eugenics,and has great clinical significance.
