超声检查高龄孕妇胎儿颈项透明层在早孕期筛查的临床应用

Clinical Application of Fetal Nuchal Translucency Sonography in Early Pregnancy of Pregnant Women in Advanced Maternal Age

目的探讨超声检测高龄孕妇胎儿颈项透明层厚度(NT)与胎儿发育异常的关系。方法对毕节市第一人民医院,在2014年1月—2017年10月间行超声检查测量NT的孕妇资料,研究比较高龄与适龄孕妇胎儿颈项透明层增厚发生率。结果在筛查的2 413例孕妇中,NT增厚异常的有82例,总异常率为3.40%。高龄孕妇的阳性率为3.48%,适龄孕妇的阳性率3.36%两组孕妇之间的胎儿NT异常增厚检出率,差异无统计学意义(P>0.05)。结论超声检测胎儿NT值可作为高龄孕妇早期胎儿发育异常筛查的重要指标,但NT值异常与孕妇年龄无关。

Objective To study the relationship between fetal nuchal translucency（NT）thickness and fetal abnormalities by sonography in pregnant women in advanced maternal age.Method The incidence of nuchal translucency in pregnant women in normal age and advanced maternal age was studied by collecting the data of the pregnant women with NT sonography in the hospital.Result Among 2 413 pregnant women,82 cases have abnormal thickening of NT,with a total abnormality rate of 3.40%.The abnormal rate of pregnant women of advanced maternal age is 3.48%,and the rate of pregnant women of normal age is 3.36%.There is of no significant difference in the detection rate of fetal NT abnormal thickening between two groups（P〈0.05）.Conclusion Ultrasound examination of fetal NT value can be used as an important indicator of early fetal development abnormalities in pregnant women of advanced maternal age,but the abnormal NT value has nothing to do with the age of pregnant women.
