“…Monique et al [14] found that hypocoiling was associated with small for gestational age infants. Chholak D et al [2] , Georgiou et al [13] , Shayesta Rahi et al [16] , and Ezimokhai M et al [17] obtained similar results in their studies Meconium staining of the amniotic fluid was found to be associated with Hypocoiled Umbilical Cords (p value 0.003) in our study. Similar findings were noted in studies done by Strong et al [10] and Ezimokhai et al [17] .…”

“…It was found that LBW (birth weight <2.5kg) was significantly associated with both hypercoiled (P = 0.016). Similar results were obtained by Rana et al [8] , Raio et al [6] , and de Laat et al [9] , Shayesta Rahi et al [16] However, the authors were unable to give a satisfactory explanation for this casual association. On contrary Shalu Gupta, MMA Faridi et al [4] did not find any significant relationship between UCI and birth weight, gestation and FGR A low APGAR Score of <7 at both 1 minute & 5 minutes was significantly associated with Abnormally coiled, Hypercoiled cords (<0.001).…”

“…Poonam Bhojwani et al [12] also found that there were more NICU admissions in babies with Hypercoiled UCI & it was significant. In the study by ShayestaRahi et al [16] the percentage of NICU admission was more (40%) in both hypocoiled and hypercoiled groups as compared to normocoiled group. Dakshayini D et al [22] also observed higher NICU admission in both hypocoiled and hypercoiled groups as compared to normocoiled group.…”

To measure umbilical coiling index (UCI) postnatally and to study the association of normocoiling, hypo coiling and hyper coiling to maternal and perinatal outcome. Method: Two hundred antenatal women who went into labour were studied and umbilical coiling index calculated at the time of delivery. UCI was determined by dividing the total number of coils by the totalumbilicalcordlengthincentimetres.Itsassociationwithselected maternal risk factors and fetal outcome were noted. The statistical tests were the Chi-square test and assessed with SPSS version 13.0 software and statistically analysed. P value of less than 0.05 was regarded as statistically significant. Results: The mean umbilical coiling index was found to be 52.87 + 9.40 cms. The mean number of coils per umbilical cord was found to be 10.19 + 1.38. The mean UCI was 0.19+0.1 coils/cm. The cut off for 10 th percentile was 0.05and 19 patients (9.5%) had Hypocoiled Umbilical Cord. The cut off for 90 th percentile was 0.32 and 20 patients (10.0%) had Hypercoiled Umbilical Cords. Hypocoiled cords were associated with Postdated Gestations, Oligohydramnios, Meconium stained liquor, Intrapartum fetal distress. While hypercoiling was associated with Pregnancy induced hypertension, Abruptio placentae, Fetal Growth Restriction, low birth weight, low APGAR scores & NICU admissions. There was no significant association between Maternal age, Gravidity, Maternal Anaemia, Gestational Diabetes Mellitus, Hypothyroidism, Polyhydramnios, PROM& mode of delivery. Conclusion:Postnatal umbilical coiling index serves as a significant indicator of maternal risk factors and fetal outcome and therefore antenatal determination of UCI can help identify high risk pregnancies to be managed with greater vigilance and monitoring.

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.

“…For example, hypocoiled artery was associated with hypertension disorder, low birth weight, fetal heart rate abnormalities while hypercoiled artery was associated with diabetes mellitus and congenital abnormalities (Chitra et al, 2012 ). As for IUGR, both hypocoiling and hypercoiling were reported but hypercoiling is more commonly observed in IUGR (Devaru and Thusoo, 2012 ; Mittal et al, 2015 ; Chholak et al, 2017 ; Rahi and Akther, 2017 ). CFD study showed that UCI has a significant effect in umbilical artery blood flow hemodynamics, whereby a hypercoiled artery experienced greater pressure drop and WSS (and thus higher flow resistance) as compared to hypercoiled artery, as shown in Figure 2 , (Kaplan et al, 2010 ; Saw et al, 2017 ; Shah et al, 2017 ).…”

A Review of Biomechanics Analysis of the Umbilical–Placenta System With Regards to Diseases

2021

View full text Add to dashboard Cite

Placenta is an important organ that is crucial for both fetal and maternal health. Abnormalities of the placenta, such as during intrauterine growth restriction (IUGR) and pre-eclampsia (PE) are common, and an improved understanding of these diseases is needed to improve medical care. Biomechanics analysis of the placenta is an under-explored area of investigation, which has demonstrated usefulness in contributing to our understanding of the placenta physiology. In this review, we introduce fundamental biomechanics concepts and discuss the findings of biomechanical analysis of the placenta and umbilical cord, including both tissue biomechanics and biofluid mechanics. The biomechanics of placenta ultrasound elastography and its potential in improving clinical detection of placenta diseases are also discussed. Finally, potential future work is listed.
