BACKGROUND: This study aimed to investigate the factors associated with the antenatal umbilical cord pitch value by ultrasound measurement in late pregnancy. We investigated the factors associated with the umbilical cord pitch value under prenatal ultrasound measurement.
METHODS: This study included 528 pregnant women who underwent routine antenatal ultrasound examinations in Ningbo Women and Children's Hospital from December 2020 to August 2021. Their umbilical cord pitch values and diameter, Wharton's jelly thickness, amniotic fluid indexes, umbilical artery blood flow parameters, and other relevant data, such as ages and gestational ages, were measured. Information about delivery methods, placenta, umbilical cord, and neonatal weight were recorded during follow-up. Statistical analysis was performed on the above data, and the factors associated with the pitch values were analyzed by linear regression.
RESULTS: This study revealed that cord torsion (p < 0.001, 95% confidence interval [CI]=-34.81 to -19.01), cord entanglement (p < 0.001, 95% CI = 10.71 to 20.11), thickening of Wharton's jelly (p = 0.001, 95% CI = 5.39 to 20.24), and cord edema (p = 0.015, 95%CI = 2.09 to 19.44), gestational age (p = 0.024, 95%CI = 0.14 to 1.89), age of pregnant woman (p = 0.009, 95%CI= -1.15 to -0.16), and neonatal weight (p = 0.011, 95%CI = 0.002 to 0.012) were significantly correlated with the pitch values.
CONCLUSION: The umbilical cord pitch value significantly correlated with cord entanglement, cord torsion, cord edema, Wharton's jelly thickening, gestational age, age of the pregnant woman, and neonatal weight. Notably, the pitch value by prenatal ultrasound measurement is predictive of cord morphological abnormalities such as cord entanglement, cord torsion, cord edema, and Wharton's jelly thickening.
