目的探讨产前彩色多普勒超声诊断胎儿胸部畸形的临床价值。方法选择2014年6月-2016年12月在该院进行产前检查的25 125例中晚期孕妇作为研究对象,对胎儿进行详细有针对性的胸部彩色多普勒超声检查,对胸部畸形胎儿行引产后尸体解剖或产后随访。结果在25 125例超声检查样本中,共检测出102例胎儿存在胸部畸形,检出率4‰。其中心脏畸形59例、肺部畸形30例、其他畸形13例,漏诊6例;经引产或正常妊娠产后随访确认,综合检出准确率94%,其中合并其他畸形31例。25~32周胎儿畸形检出数最多,说明此时为最佳胎儿畸形筛查时间,其他依次为33~42周、18~24周、16~17周。结论彩色多普勒超声对胎儿胸部畸形诊断的准确率较高,适用于产前筛查,具有重要的临床诊断价值。
Objective To investigate the clinical value of prenatal color Doppler ultrasound in the diagnosis of fetal thoracic deformity. Methods Totally 25 125 middle- and late-stage pregnant women who performed prenatal examinations in our hospital from June 2014 to December 2016 were selected as the study subjects. The fetus was examined by detailed color Doppler sonography, Postpartum autopsy or postnatal follow-up. Results Totally 102 fetuses with thoracic deformities were detected in 25 125 ultrasonography samples and the detection rate was 4 ‰. There were 59 cases of cardiac malformations, 30 cases of deformities of the lungs, 13 cases of other malformations and 6 cases of misdiagnosis. The post-natal follow-up confirmed by induction of labor or normal pregnancy showed that the accuracy was 94%, of which 31 cases were complicated by other malformations. The highest number of fetal malformations was detected in 25 to 32 weeks, indicating that the best screening time for fetal malformations was at this time, followed by 33 to 42 weeks, 18 to 24 weeks and 16 to 17 weeks. Conclusion The accuracy of color Doppler ultrasound in the diagnosis of fetal thoracic deformity is high, which is suitable for prenatal screening and has important clinical diagnostic value.
