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.
