Abstract

Abstract

The umbilical cord represents a unique lifeline between the fetus andmother and contains two arteries and one vein wrapped up in Wharton’s jelly with moderate twists. Umbilical coiling abnormalities canresult in fetal growth restriction, fetal distress, or intrauterine fetal death.

Hypocoiled umbilical cords are associated with intrauterine fetal death (IUFD), fetal growth restriction, fetal distress, low Apgar scores, fetal congenital anomalies, and abnormal insertion of the umbilical cord. Hypercoiled umbilical cords are associated with IUFD, fetal distress, asphyxia, fetal congenital anomalies, and the presence of a single umbilical artery.

The aim of this work is to determine if the umbilical Cord coiling index measurement during second trimester ultrasound scan can predict perinatal outcome. Seventy eight healthy uncomplicated pregnant women who regularly attended the antenatal care clinic for antenatal care and to do anomaly ultrasound scan on her baby in 2nd trimester.

All participants were informed about the aims and the procedures of the study and signed an informed consent form prior to beginning.

Regular antenatal care visit was done every two weeks till delivery with assessment of perinatal outcomes regarding: gestational age at delivery, fetal monitoring by CTG, method of delivery, meconium staining amniotic fluid or not, examination by apgar score at 1stand 5th minute, birth weight, admission to NICU or not and perinatal death.

According to umbilical cord index, of total 78 pregnant women who completed the study 62 (79.2%) were having normal UC coiling, 10 of cases (12.8%) were having hypocoiling and 6 (7.7%) were having hypercoiling.

Our results showed that hypo- and hyper-coiling were associated with increased incidence of preterm labor (32-36 weeks) “22.2%and 40% respectively” while normo-coiling was associated with lesser incidence “2%”. Both hypocoiling “10%” and hypercoiling “16.7%”groups showed higher incidence of IUGR when compared with the normocoiling group “1.6%”. APGAR score at minute one was significantly lower in the both hypocoiling and hypercoiling groups than the normocoiling group with p- value: 0.005. While at minute five, there was no significant difference between the three groups of the study.

Conclusion: The abnormal umbilical coiling index “< 10th percentile or > 90th percentile” is associated with adverse perinatal outcomes. Therefore, early evaluation on Umbilical cord Index in the 2nd trimester can identify fetuses who are at risk and thus help in further management.

Introduction

The umbilical cord is vital for development, wellbeing and survival of the fetus and it is vulnerable to kinking, compression, traction and torsion, which may affect the perinatal outcome [1].

Vessels of the umbilical cord have a spiral course (pass along the length of the cord in helical fashion). This is called "coiling"of the umbilical cord, which changes as pregnancy advances [2].

A coil is defined as a completed 360 spiral course of umbilical vessel around warton jelly. The umbilical cord coils by the umbilical cord in length in centimeter and called "index of twist" [3].

As measurement of the total length of the cord is not feasible prior to birth, Strong et al simplified calculation of the cord coiling and named it"the umbilical cord coiling index"(UCI). It is calculated as the reciprocal of the length of one complete coiling in centimeters measured antenatally by ultrasound [4].

Abnormal cord coiling index include both hypocoiled cord (cord with abnormal cord coiling index which is below 10th percentile) and hypercoiled cords “cord with an umbilical cord coiling index which is more than90th percentile” [5].

The cause, role and mechanism of umbilical cord coiling have not been elucidated; nonetheless, it has been shown that hypocoiled or hypercoiling of the umbilical cord during 2nd trimester is associated with adverse perinatal outcome such as intra uterine fetal death, intrauterine growth restriction, pre-term labor and fetal distress during labor; consequently, with increased delivery of a low-birth-weight fetus and admission to the neonatal intensive care unit [6].

Aim of the work

The aim of this work is to determine if the umbilical Cord coiling index measurement during second trimester ultrasound scan can predict perinatal outcome.

VI.Statistical Analysis

All statistical calculation were done using computer program SPSS (statistical package for social science; SPSS Inc., Chicago, IL, USA) version 15 for Microsoft Windows.

Results

The percentage of patients who completed the study were 88.6% (78/88), while only 11.4% were withdrawn (10/88) from the study. Of these 10 cases, 4 were excluded because of preeclampsia, 2 were excluded because gestational DM,1 was excluded because of traffic accident, and the 3 cases were excluded because they didn’t attend the antenatal care.

The 78 cases that had completed the study were classified according to the UCI by using ultrasound (at gestational age 22: 26weeks) into; 79.2% (62/78) were diagnosed to be normocoiling, 12.8% (10/78) were diagnosed as hypocoiling, and the rest 6 cases in percentage of 7.7% were diagnosed as hypercoiling. There was not a statistically significant difference between the three groups of the study as regard parity. On the other hand, the majority of the normocoiling group patients were <35>p-value: <0>. There is no statistically significant difference between the three groups of the study as regard gestational age, fetal weight at time of examination (22: 26 weeks) and Amniotic fluid index.

There is no statistically significant difference between the three group

groups of the study as regard IUFD, IUGR and fetal heart rate abnormalities (fetal distress) during antenatal follow up visit.

One IUFD in each of three group occurred during follow up and those patients were excluded from the following tables.

There was a high statistically significant difference between the three groups of the study as regard mode of delivery showing higher rates of Cesarean section in hypocoiling and hypercoiling groups than in the normocoiling group with p-value: <0>.There is also a statistically significant difference between the 3 groups as regard gestational age at delivery with p-value: 0.009.

As regard the perinatal outcomes of the three groups of the study, there was a statistical significant difference between them as regard.

APGAR score minute one with p-value: 0.005 with higher rate in the hypocoiling and hypercoiling groups. Also, there was a high statistical significant difference between the studied groups as regard need for Neonatal ICU admission with p-value: <0>with higher rate in the hypocoiling and hypercoiling groups.

Discussion

The umbilical cord is a very important structure connecting the placenta and the fetus. It consists of 3 blood vessels, and it has the characteristic of screw-shaped coils. The cause, role and mechanism of umbilical cord coiling have not been elucidated; nonetheless it has been shown that the coiling level is associated with adverse perinatal outcome such as intrauterine fetal death, intrauterine growth restriction and fetal distress during labor [8].

Many studies have been carried out evaluating the relationship between UCI and various maternal and fetal outcomes though majority of them have been based on the postnatal UCI. Both hypocoiling and hypercoiling have been linked to various adverse perinatal outcomes [8].

In the light of these studies and keeping in mind the need for further evaluation of the credibility of the antenatal umbilical coiling index, this study was planned to assess the role of the antenatal umbilical coiling as a predictor of adverse perinatal outcome.

According to umbilical cord index, our results showed that of the 78 pregnant women participating in this study, 62 women “79.5%” showed normocoiling, 10 women “12.8%”showed hypocoiling, while 6 women “7.7%” showed hypercoiling.

These results were in agree with that of Patil et al., (2019) who reported in there study on 200 pregnant women that 156 cords “78%” showed normal coiling, 23 “11.5%” showed hypocoiling, and 21 “10.5%” showed hypercoiling [9].

Mittal et al., (2015) found similar results on their study on 200 pregnant women with uncomplicated, singleton pregnancy. They found hypocoiled -UCI <10th>9%);normocoiled- with UCI between 10th –90th percentile (81%) andhypercoiled- UCI >90th percentile (10%) [10].

Also, the study of Adesina et al., (2017) onthe umbilical cords of 436 neonates showed that Normal UCI was observed in 351 (80.5%) neonates, 44 (10.4%) and 41 (9.1%) neonates had hypo- and hypercoiled cords, respectively [11].

The participating women in our study were divided according to the UCI into three groups: normocoiling, hypocoiling, and hypercoiling groups. And further statistical analysis was done on these three groups andour results showed.

As regard maternal age, our results showed that maternal age in normocoiling group was lower than in the other two groups with significant difference between them “p-value: 0.002”as shown in table (2).And when compared between the three groups as regard age < or > 35old we found also a statistical significant difference with  p-value <0>indicating that abnormal umbilical cord coiling was common in women > 35 ys.

In harmony with our results was Chitra et al., (2012) as they reported that they found in their study on one thousand antenatal women an association between elderly gravida (>35 years) and both hypocoiled andhypercoiled (P = 0.041 and P = 0.003, resp.) [12].

While Adesina et al., (2017) was against our results and reported that there was there was no statistically significant difference when maternal age, parity and gestational age were compared in the hypocoiled, normocoiled and hypercoiled groups [11].

As regard parity, our results showed that there was no statistically significant difference between the groups of the study with p-value: 0.1.

These results go in harmony with Adesina et al., (2017) as they reported no statistically significant difference when compared parity in their three groups of the study [11].

Also, Patil et al., (2019) reported that on comparing UCI with parity, it was found that there was no statistical significance between primigravida and multigravida [9].

As regard gestational age, at first visit our results showed no significant difference between all groups of the study with p-value: 0.8.

But when we measured the effect of UC coiling abnormalities, our results showed that hypo- and hyper-coiling were associated with increased incidence of preterm labor “22.2% and 40% respectively” while normo- coiling was associated with lesser incidence “2%”.

These results go in agree Jo et al., (2018) who reported on their retrospective study of 251 pregnancies in which a fetal anatomic survey with a recorded UCI was performed at 22-28 weeks gestation that there wasno significant difference between the three groups of their study as regard gestational age at first evaluation. And as regard preterm delivery bothhypocoiling and hypercoiling groups shows higher incidence of preterm delivery “36.4% and 16.7% respectively” than the normocoiling group “7.7% with (p=0.041) [8].

Against these results was Ohno et al., (2016) who reported on their retrospective study, 200 consecutive umbilical cords, that there was no significant difference between the three groups of the study as regard gestational age at birth and incidence of preterm labor [13].

As regard fetal birth weight, at first visit our results showed no significant difference between the three groups of the study with p-value:

0.4. Revaluation of fetal birth weight at delivery time showed also no significant difference between the three groups of the study with p-value:

0.09 despite that both hypo and hypercoiling groups were associated with lower birth weight than the normocoiling guop.

These results go in harmony with Mittal et al., (2015) who reported that Out of the 200 newborn babies, 12 weighed less than 2,500 gm,i.e., were low birth weight babies. Three babies out of these belonged to the hypocoiled group and four belonged to the hypercoiled group. Both hypo- and hypercoiling were found to be significantly associated with low birth weight with p-value “0.0344 between hypocoiling group and normocoiling group and p-value: 0.0095 between hypercoiling and the normocoiling group”. This may well be explained by the increased number of preterm deliveries in the hypocoiled group and a higher number of small for gestational age babies in the hypercoiled group.

While, Jo et al., (2019) found a significant difference between the three groups of the study as regard the incidence of neonates with low birth weights and the incidence in the hypocoiled and hypercoiling groups was 36.4% and 20% respectively, which was significantly greater than the normocoiled groups “10%” with (p=0.044) [8].

However, Kashanian et al. (2016) and de Laat et al. (2017) noted overcoiling and low weight at birth to be significantly related. [14, 15]

As regard the amniotic fluid index, our results showed that there wasno significant difference between the three groups of the study with “p-value: 1.0”.

The results of Jo et al., (2018) showed also no significant difference between their three groups as regard amniotic fluid index [8].

We studied the effect of umbilical cord coiling index abnormalities on fetal outcomes, and we found the following results.

As regard intrauterine growth restriction “IUGR”, our results showed no statistically significant difference between the three groups of thestudy with p-value: 0.1. Both hypocoiling and hypercoiling groups showed higher incidence of IUGR when compared with the normocoiling group with percentage of 10% and 16.7% vs 1.6% [8].

Similar to our results were in agree with Joet al., (2018) who found also no significant difference between their study groups as regard incidence of IUGR in both hypocoiling and hypercoiling group vs the normocoiling group “20% and 25% vs 9.3%” [8].

Against our results was Dakshayini and Meghna, (2020) who found a significant difference between their three groups “p: 0.003”. The higher incidence of IUGR was found in their study in hypercoiling and normocoiling groups “73.3% and 49.3%” while it was lowest in the hypocoiling group “8.3%” [16].

Also, Patil et al., (2019) was against our results as they found a statistically significant difference between their groups “p: <0>

Also, our results showed no significant difference as regard intrauterine fetal death “IUFD” with similar distribution to that in IUGR with p-value: 0.4.

As regard abnormalities of fetal HR, our results showed no significant difference between the three studied groups neither during pregnancy nor during labor with p-value: 0.4 and0.5 respectively.

As regard mode of delivery, our results show a significant difference between the groups with p-value: <0>

These results were in agree with Patil et al., (2019) who found alsoa significant difference between the three groups of the study “p- value: 0.08” with higher incidence of CS in both hypo and hyper-coiling groups while the normo-coiling group showed higher incidence of vaginal delivery [9].

As regard meconium staining of then amniotic fluid, our results showed no significant difference between the three groups of the study with p-value: 0.4. However, this non-significant difference both hypo- and hyper- coiling groups showed higher incidence of meconium staining the normo-coiling group “33.3% and 40% Vs 6.6%”.

Similar to these results Mittal et al., (2015) found no significant difference between hypocoiling, hypercoiling and normocoiling groups as regard meconium staining of amniotic fluidwith  p-value  “1.000  and 0.300 respectively” [10].

Also, Predanic et al., (2017) found that meconium staining of amniotic fluid was observed more frequently in the group of hypo- and hyper-coiled cords (25.8% [8/31 fetuses] and 22.2% [6/27 fetuses], respectively) rather that in the normocoiled group of subjects (13.1% [31/236 fetuses]). This, however, was not statistically significant (P =

.212, chi-squared test; degrees of freedom, 3.107, 2) [17].

As regard fetal asphyxia, our results showed no significant difference between the three studied groups with p-value: 0.1.

De Laat et al. (2016 a and b) found hypercoiled to be significantly associated with birth asphyxia-acute and chronic [18].

As regard APGAR score, at minute one our results showed that there was a significant statistical association “p-value: 0.005” between the three group of our study with higher incidence of low scores with hypocoiling and hypercoiling groups “44.4% and 40% vs 8.2% in normocoiling group”. While at 5 min, our results showed no significant association “p-value: 0.1” between the three group of our study with higher incidence of low scores with hypocoiling and hypercoiling groups “11.1% and 20% vs 3.3% in normocoiling group”.

Devaru and Thusoo, (2018) found a similar significant association as regard APGAR score at 1 min with p-value: <0>

The result of Mittal et al., (2015) was against our result at APGAR score at 1 min as he found no significant association between their study groups but was agree with ours as regard APGAR score at 5 min with no significant association was found and reported in general that there was no association between poor APGAR scores and umbilical cord coiling abnormalities [10].

Jo et al., (2018) was also against our results as regard APGAR score at 1 min as they found no significant association between their study groups [8].

Adesina et al., (2017) was agree with our results as regard APGAR at 5 min as they found no significant association between their study groups with p-value: 0.201 [11].

As regard the need for neonatal ICU admission, our results showed significant association between the three studied groups with value: <0>

Our results were in agree with Patil et al., (2019) as they found a significant association in the hypocoiling and hypercoiling groups and NICUadmission when compared with the normocoiling group with p- value: <0>

Against our result was Mittal et al., (2015) who found no significant association between their both hypocoiling and hypercoiling groups vs the normocoiling group as regard NICU admission with p- value: 1.000. in this study no NICU admission was recorded in the hypocoiling and hypercoiling groups while 3 cases were recorded in the

nornociling group [15].

Also, Adesina et al., (2017) found no significant difference between was observed in their study as regard NICU admission with p- value: 0.976 [11].

Conclusion

The abnormal umbilical coiling index “< 10th percentile or > 90th percentile” is associated with adverse perinatal outcomes. Therefore, early evaluation on Umbilical cord Index in the 2nd trimester can identify fetuses who are at risk and thus help in further management.

I am very pleased to serve as EBM of the journal, I hope many years of my experience in stem cells can help the journal from one way or another. As we know, stem cells hold great potential for regenerative medicine, which are mostly used to promote the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. I think Stem Cell Research and Therapeutics International is a great platform to publish and share the understanding towards the biology and translational or clinical application of stem cells.
