目的探讨中晚孕胎儿超声在产前筛查中胎儿畸形漏诊的原因,提高胎儿畸形检出率。方法回顾性分析2011年1月-2013年12月中晚孕胎儿超声17 680例,检出胎儿畸形86例,经产后证实胎儿畸形漏诊13例,对其漏诊的13例进行对照分析漏诊原因。结果胎儿先天畸形86例中漏诊13例,分别为唇腭裂3例,前臂缺失1例,足内翻1例,手指异常3例,外耳异常2例,部分型心内膜缺损1例,室间隔缺损2例。结论总结中晚孕胎儿超声筛查胎儿结构畸形漏诊的经验教训,采取相应措施,提高胎儿畸形的检出率,减少出生缺陷,优化出生人口。
Objective To investigate the causes of misdiagnosis of fetal malformation in prenatal screening of fetus in middle and late pregnancy and to improve the detection rate of fetal malformation. Methods A retrospective analysis of 17 680 fetuses in middle and late pregnancy from January 2011 to December 2013 was retrospectively analyzed. Tire malformations were detected in 86 cases. After birth, 13 cases were misdiagnosed as fetal malformations and 13 cases were missed for missed diagnosis. Results Among the 86 cases, 13 cases missed the diagnosis of fetal congenital malformations, including 3 cases of cleft lip and palate, 1 case of forearm deformity, 1 case of foot varus, 3 cases of abnormal finger, 2 cases of abnormal outer ear, 1 case of partial endocardial defect, 2 cases of defect. Conclusions The results of the missed diagnosis of fetus structural abnormalities in middle and late pregnancy fetuses were summarized and corresponding measures were taken to improve the detection rate of fetal malformations, reduce birth defects and optimize the birth population.
