Abstract

Background: The purpose of this study was to evaluate the prognostic significance of sonographic measurement of the umbilical coiling index in term pregnancy & it's a relation to pregnancy outcome. Objectives: This study was designed to measure the umbilical coiling index antenatally in term pregnancy (prior to the onset of uterine contractions) for a group of pregnant women and clarify the relationship between the umbilical coiling index and perinatal outcomes. Study design: a cross-sectional study. Methods: This study included (100) cases of pregnant women with uncomplicated, term, singleton pregnancies (free of labor pain), and all participants were examined by color Doppler ultrasound, during which umbilical cord cross-sectional area, umbilical vessels cross-sectional area, and umbilical coiling index were calculated and compared with Doppler parameters including umbilical vein blood flow volume, umbilical vein peak systolic velocity and umbilical artery pulsatility index. The ultrasound findings were correlated with intrapartum and neonatal outcomes. The Doppler parameters divided according to the umbilical cord cross-sectional area while regarding the perinatal outcomes, the studied sample divided into three groups according to umbilical coiling index values (hypercoiled, hypocoiled & normocoiled umbilical cord). Results: Our study revealed that: The crosssectional area of the umbilical cord was below the 10th percentile in 14% of fetuses. Birth weight and placental weight were in the lower limits in fetuses with the lean umbilical cord. Most of the umbilical cord parameters measured by ultrasound were of lower values in fetuses with the lean umbilical cord. Results of measurement of the umbilical coiling index showed that in 15% of fetuses, the umbilical coiling index was below normal values and in 9% of fetuses, the umbilical coiling index was above normal values and abnormal values of the umbilical coiling index were associated with adverse perinatal outcomes. There is a weak negative correlation between the umbilical coiling index and the neonatal birth weight and a moderate positive correlation between the umbilical vein blood flow volume and umbilical cord cross-sectional area.
