NT值超声测定在孕11~13+6周胎儿畸形诊断中的价值

摘要

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( χ2=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.%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（χ2=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。
