超声测量胎儿颈项皮肤厚度的初步研究

目的 通过超声检查寻找合适的胎儿颈项皮肤厚度（NT）临界值。方法 对67例早期妊娠（孕10-14周）病例进行超声检查测量颈项皮肤透明层厚度。结果 4例发现异常。1例NT4.0mm因心血管畸形而终止妊娠;1例VT3.6mm为21-三体;2例难免流产 其NT分别为2.7mm 1.9mm.结论 早期妊娠对作超声检查测量NT,对异常者作超声随访或染色检查,可提高胎儿畸形的早期诊断率。早期妊娠时作超声检查测量 NT已成为筛胎儿畸形的一个新指标。

Preliminary study of measuring fetal nuchal translucency thickness by ultrasound

Objective To find suitable critical value of fetal nuchal translucency (NT) by ultrasonic testing. Methods 67pregnant women with gestational age of 10-14 weeks were measured for nuchal translucency thickness by ultrasonic testing. Results Four cases were abnormity: one case who's NT was 4.0mm terminated pregnancy because of cardiovascular abnormity; one case of trisomy 21 who's NT was 3.6mm; two cases terminated pregnancy because of inevitable abortion their NT were 2.7mm and 1.9mm. Conclusion In early pregnancy, we can measure NT value by ultrasound. She can choose ultrasonic follow-up survey or chromosome testing. if her fetal's is abnormity, Measuring NT by ultrasound in the early pregnancy is a new index in screening the abnormity of fetus.
