Abstract

Increased nuchal translucency (NT) in the first trimester is a key ultrasound marker for early detection of congenital abnormalities and for predicting perinatal outcomes. Objective: To describe postnatal outcomes in fetuses with increased nuchal translucency. Subjects and Methods: A retrospective cross-sectional study was conducted on 320 pregnant women with nuchal translucency (NT) ≥ 2.5 mm who underwent amniocentesis at the Prenatal Diagnosis Center – National Hospital of Obstetrics and Gynecology, from February 2022 to February 2024. Results: The overall live birth rate was 70.0%. The highest rates of postnatal abnormalities and perinatal mortality were observed in the NT 5.0–5.9 mm and ≥ 6.0 mm groups. Specifically, the rates of postnatal abnormalities were 8.3% and 4.8%, while rates of fetal or neonatal death were 37.5% and 57.1%, respectively. Most infants had a birth weight between 2500 and <4000 g (90.6%), and 98.7% achieved Apgar scores of 7–10. Conclusion: Fetuses with increased NT are at higher risk of adverse perinatal outcomes, even with a normal karyotype. NT measurement should be interpreted alongside close follow-up and comprehensive counseling to guide appropriate pregnancy management.
