NT值超声测定在孕11~13^(+6)周胎儿畸形诊断中的价值

Value of NT Value Ultrasonic Measurement in the Diagnosis of Fetal Malformation at 11-13^(+6) weeks

目的:探讨NT值超声测定在孕11~13^(+6)周胎儿畸形诊断中的应用价值。方法:纳入2014年1-12月来本院接受孕期检查的3822例孕11~13^(+6)周孕妇作为研究对象,采用超声测量3822例孕妇胎儿的NT(颈项透明层)值,进行胎儿畸形诊断。结果:3822例孕妇共3869例胎儿,经筛查发现109例为畸形胎儿。109例畸形胎儿中,NT值≥2.5 mm的胎儿共84例,所占比例为77.1%,明显高于NT值<2.5 mm的胎儿(X^2=63.872;P<0.05)。结论:孕11~13^(+6)周时测定胎儿NT值可作为筛查胎儿畸形的重要方法,NT值≥2.5 mm为筛查胎儿畸形的重要参考指标。

Objective： To explore the value of NT value ultrasonic measurement in the diagnossis of fetal abnormalities at 11-13^＋6 weeks.Method ： From January 2014 to December 2014 3822 cases examined for pregnancy in our hospital at 11-13＋6 weeks pregnant women as the research objects, USES the ultrasonic measurement of 3822 cases of fetus NT transparent layer （ neck ） value, the diagnosis of fetal abnormalities.Result： 3822 cases of pregnant women, a total of 3869 cases of fetus, the screening found 109 cases of malformation fetus.109 cases of malformation fetus, NT value ≥ 2.5 mm, a total of 84 cases of fetus, the proportion was 77.1%, was significantly higher than the NT value〈2.5 mm of fetus （ X2=63.872, P〈0.05 ） .Conclusion： At 11-13＋6 weeks of pregnancy fetal NT value can be used as the important way of screening for fetal malformation, NT value≥2.5 mm important reference index for screening fetal abnormalities.
