Aim: To study the association between antenatal umbilical cord coiling index (aUCI) and perinatal outcome.
Materials and methods: This prospective study was conducted on 100 patients. The aUCI between gestational age 28 and 42 weeks was calculated by color Doppler as the reciprocal of the distance between a pair of coils. It was then correlated with the following pregnancy outcomes: mode of delivery, preterm delivery, birth weight, meconium staining, Apgar score at 1 and 5 minutes, and neonatal intensive care unit (NICU) admissions. Hypocoiled cords were those having umbilical cord coiling index (UCI) less than 10th percentile and hypercoiled cords were those having UCI >90th percentile. The results were statistically analyzed by chi-square test.
Results: The mean UCI was 0.61 ± 0.16. The hypocoiled umbilical cords (UCI < 10th percentile) were significantly associated with low birth weight, meconium staining, low Apgar score at 1 minute, and increased NICU admissions with a p-value < 0.05.
Conclusion: Hypocoilled cords are significantly associated with adverse perinatal outcome.
