摘要 目的建立南京地区11~14周胎儿颈项透明层厚度(NTT)的参考值,为开展产前超声筛查提供参考依据。方法超声筛查1233例11~14周胎儿NTT,随访观察至胎儿出生,并进行统计学分析。结果获得各孕周胎儿NTT的参考值范围。通过筛查及随访观察检出染色体异常儿及结构异常儿17例。结论通过胎儿NTT的测量及随诊超声观察可有效地检出染色体异常高危儿及结构异常儿。 Objective To investigate a normal value of nuchal translucency thickness(NTT) of fetus with gestation of 11-14 weeks in Nanjing district for providing a reference for prenatal ultrasonographic screening.Methods Nuchal translucency thickness of 1233 fetus with gestation of 11-14 weeks was measured with ultrasonography,who were followed-up till borth.Results The normal limits of NTT in fetus with gestation of 11-14 weeks in Nanjing district were obtained.By ultrasonographic screening and following-up,17 fetuses with abnormal karyotype or abnormalities were identified.Conclusion Fetuses with high danger of abnormal karyotype and futuses with abnormalities can be detected by measurements of NTT in 11-14 weeks gestation with ultrasonographic screening.
