NT超声检查技术在早孕期胎儿异常筛查中的应用效果分析

Application effect analysis of NT ultrasound technique in screening fetal abnormalities in early pregnancy

目的评价颈项透明层(NT)超声检查在早孕期胎儿异常筛查中的价值。方法选取1100例检查的孕妇,全部行NT超声检查,然后再将NT超声所示的胎儿异常与最终染色体基因检测及出生结果比较。结果在1100例进行NT超声检查中,出现胎儿异常共1.91%(21/1100)。其中,NT检查胎儿异常为NT增厚、水囊瘤的分别占比57.14%(12/21)、14.29%(3/21),出现腹腔内囊肿、左侧脉络丛异常回声、脐膨出、单脐动脉、三尖瓣反流、胎盘囊肿各占比4.76%(1/21)。而在实际的分娩过程中出现19例胎儿异常,总体诊断率为90.48%。结论NT超声检查技术是一种有效地早期诊断胎儿结构异常的方法,有效地评估胎儿染色体非整倍体风险,能为产科和妇科临床工作提供有价值的数据,具有较高的临床应用价值。

Objective To evaluate the value of ultrasound examination of nuchal transparent layer(NT)in screening for fetal abnormalities in early pregnancy.Methods A total of 1100 pregnant women were selected for NT ultrasound examination,and then the fetal abnormalities shown by NT ultrasound were compared with the final chromosomal genetic examination and birth results.Results Among 1100 cases of NT ultrasonography,1.91%(21/1100)had fetal abnormalities.Among them,57.14%(12/21)and 14.29%(3/21)of the fetal abnormalities in NT examination were NT thickening and hystoma,respectively.Intra-abdominal cyst,abnormal echo of left choroid plexus,omphalocele,single umbilical artery,tricuspid valve reflux,and placental cyst were 4.76%(1/21),respectively.In the actual process of delivery,19 cases of fetal abnormalities occurred,and the overall diagnosis rate was 90.48%.Conclusion NT ultrasonography technique is an effective method for early diagnosis of fetal abnormalities,it can provide valuable data for obstetrics and gynaecology clinical work,and has high clinical application value.
