“…A study conducted by Milani et al reported insignificant differences among parity of the pregnancy across coiling indexes with a p-value of 0.26 which is in agreement with the current study p-value of 0.31 [ 18 ]. The study conducted by Patil et al tested for the association of UCI with adverse outcomes that revealed a significant difference in terms IUGR with p-value < 0.01 similar to our study findings [ 19 ].…”

BackgroundThe umbilical cord coiling index (UCI) is usually measured sonographically during antenatal follow-up and can be used to determine the fetuses at risk of adverse outcomes. MethodologyUCI measured antenatally and postnatally whose correlation is studied along with the association of abnormal UCI with the adverse outcomes in terms of gestational age, intrauterine growth restriction (IUGR), intra-uterine death, birth weight, sex, neonatal intensive care unit (NICU) admission, the color of the liquor, Amniotic Fluid Index (AFI), Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) score at one min and five mins and mode of delivery. All parameters are tested for significant differences among UCI and a pvalue < 0.05 is considered significant. The correlation of UCI measured antenatally and postnatally is tested using the spearman correlation coefficient. ResultsA strong correlation is found between antenatal UCI and postnatal UCI with r s 0.9. The majority of the population had normo coiling. Hyper and hypo coiling are associated risks of emergency lower segment cesarean section (LSCS). Low birth weight is seen in 88.89% of hypo coiled patients with a p-value < 0.01. The coiling index among sex is found to be insignificant with a p-value of 0.81. Meconium-Stained Liquor (MSL) is seen in 78.5% of hyper coiled patients. IUGR is found to be associated with hypo coiling as seen in 59.2% of patients with significant p-value (< 0.01). Age, gestational age, and birth weight are found to be statistically significant between various coiling indexes with p-value < 0.05. ConclusionAntenatal UCI correlates with postnatal UCI and any abnormal index found can be used as a predictor of adverse perinatal outcomes and help obstetricians to monitor continuously and put the patients at risk on prophylactic measures.

“…A study done by Milani et al, found a significant difference between abnormal umbilical cord coiling index and gestational hypertension. 27 Lv et al concluded that hypercoiling of cord was found more predominantly in pre-eclampsia patients. 28 Similarly, a study done by Tripathy et al concluded that there was a significant relationship between hypocoiling of umbilical cords and pregnancy induced hypertension.…”

: Fetal compromise as a major contributor to neonatal morbidity is of great concern for obstetricians. Antenatal risk assessment profiles are often insufficient in picking up these cases and hence need to be improved. Antenatal Umbilical cord Coiling Index (AUCI) is one such potential predictor which helps in identifying pregnant women who need close antepartum and intrapartum monitoring. It is determined by ultrasonogram antenatally and noted to be fixed throughout the pregnancy. This study aims at determining the association between AUCI and pregnancy outcome.: This was a hospital based prospective analytical study conducted in a tertiary care centre in Pondicherry from January 2019 to May 2020. 207 pregnant women were included in the study and Colour doppler was performed and AUCI was noted. Participants were followed until delivery and pregnancy outcomes were noted.: Chi square and Fischer exact test: In the present study, among 207 subjects, 166 had normal AUCI i.e., 0.41 to 0.61. Hypocoiling was noted in 20 (< 0.41) and hypercoiling in 21(>0.61) subjects. Hypocoiling was associated with hypertension and oligohydramnios in10% cases each. Nonreasssuring fetal (NRFHR) heart rate, meconium stained liquor and low APGAR values were present in 15, 20 and 10% cases respectively. Hypercoiling was associated with diabetes (10%), hypertension (5%), oligohydramnios (10%), polyhydramnios (5%), NRFHR (10%) and meconium stained liquor (5%). However, there was no statistical significance among the above mentioned parameters.

Umbilical cord (UC) represents the “life source”, or the “entry and exit” point of humans which is the only source of energy. It is essential for the development, well-being, and survival of the nourishing baby. The characteristic of the coiling of the umbilical cord makes the cord a structure that is both ﬂexible and strong and provides resistance to external forces which could compromise the blood ﬂow to the foetus. UC is vulnerable to kinking, compressions, traction, and torsion, which may affect the intrauterine life and perinatal outcome due to coiling. One complete spiral of 360º of the umbilical vessels around each other is defined as Umbilical Coil. Abnormal coiling is defined as UCI less than the 10th percentile (i.e., Hypocoiled cord), UCI more than the 90th percentile (i.e., Hypercoiled cord), and the UCI between 10th and 90th percentile is Normocoiled cord. According to the literature studies, hypercoiled cords are usually associated with intrapartum foetal acidosis and asphyxia, foetal growth restriction, vascular thrombosis, and cord stenosis while the increased incidence of foetal demise, intrapartum FHR deceleration, low APGAR scores, preterm delivery, chorioamnionitis, structural and chromosomal abnormalities, and operative delivery have been associated more with hypocoiled cords. Hence, if the umbilical coiling index can be measured reliably in utero by ultrasound antenatally, then in future, it might become a promising prognostic marker for a better pregnancy and adverse foetal outcome.
