摘要
目的:探究颈项透明层厚(NT)超声检查在早孕期胎儿筛查中的临床价值。方法:研究对象为2018年5月-2020年11月在本院500例孕11-13^(+6)周孕妇,采用超声对胎儿颈项透明层厚进行评估测量,并将其测量结果同随访结果进行对比。结果:500例孕产妇中,仅NT≥2.5 mm者16例,其中14例正常胎儿,1例至中孕期胎死宫中,1例异常胎儿引产;NT≥2.5 mm合并其他异常4例,均引产;NT<2.5 mm合并超声软指标2例,均正常分娩。结论:早孕期NT超声检查可以有效筛查胎儿异常,对胎儿预后评价有指导意义,此方法值得应用与推广。
Objective:To study the mutation screening value of NT(nuchal translucency)examinations in first trimester of fetus.Methods:500 pregnant women with 11~13^(+6) gestational weeks checked from May 2018 to November 2020 in our hospital were chosen as research subjects.The ultrasonography was used to measure NT values;the examination results and follow-up visits conditions were compared.Results:16 cases had NT≥2.5 mm,including 14 normal fetuses,one stillborn foetus in the second trimester and one induced labor fetus.4 fetuses of NT≥2.5 mm were complicated with other abnormalities and received the induced labor.2 fetuses of NT<2.5 mm were complicated with ultrasonographic soft markers and received the normal labor.Conclusion:NT examinations are of great importance to early screening of fetal abnormalities and evaluation of fetal prognosis.
