Correlation of thickened nuchal fold with fetal chromosomal abnormalities among 919 cases / 中华医学遗传学杂志

ABSTRACT

Objective@#To explore the correlation between fetal nuchal fold (NF) thickening and fetal chromosomal abnormality.@*Methods@#In total 919 pregnant women undergoing ultrasound examination were selected for interventional prenatal diagnosis in order to detect fetal chromosomal abnormality.@*Results@#The detection rate of chromosomal abnormality has significantly increased with NF thickness, advanced maternal age, presence of other ultrasound abnormalities (P<0.05). Trisomy 21 was the most common abnormality, and there was a prepondance for male fetuses.@*Conclusion@#Increased NF thickness is strongly associated with the risk of fetal chromosomal abnormalities, advanced maternal age and presence of additional ultrasound abnormalities.
