Background: Throughout the fourth week of embryonic development the umbilical cord (UC) is formed, which corresponds to the fifth to the twelfth weeks of gestation. Fetuses with intrauterine growth restriction (IUGR) have leaner UCs than fetuses of appropriate gestational age do, and the caliber of the umbilical vein decreases significantly, resulting in a worsening of the Doppler parameters of the umbilical artery in the mother. The goal of this study was to evaluate the significance of sonographic UC diameter in determining gestational age in third trimester in pregnant women. Methods: We conducted a comparative cross-sectional research on 300 pregnant women aged range between (20-35) years, singleton gestation, gestational age (3rd) trimester estimated from antenatal mothers last menstrual period (LMP), viable fetus, presenting to obstetrics and gynecology department at Tanta university hospital. Results: Highly statistically significant positive correlation between UC diameter and gestational age, BPD, FL, AC, AFI, and estimated fetal weight was found. The increase in UC diameter was positively and significantly correlated with the increase in gestational age and estimated fetal weight, indicating that those who have prolonged gestational age and estimated fetal weight are more likely to have wider UC diameter. Conclusions: The UC diameter (UCD) has the potential to be a valuable indicator of fetal growth, well-being, and perinatal outcome. Sonographic measurement of UC diameter could be an efficient method of measuring fetal growth and predicting gestational age (GA), particularly between 28-40 weeks GA. It is possible that abnormal UC diameter can be a strong indicator to identify antenatal mothers at risk for IUFD and poor fetal outcomes.

Background: We measure the umbilical cord thickness of newborn just after delivery with digital Vernier caliper and correlate the association with antenatal maternal risk factors. This helps the pediatricians to predict which newborn need close monitoring. Objectives: The aim of indexed study to evaluate the umbilical cord thickness, maternal antenatal risk factors and determines the association between umbilical cord thickness and antenatal maternal risk factors. Methods: This is a cross sectional prospective study conducted between 2020 and 2021 at Rajkiya Mahila Chikitsalaya, J L N Medical College, Ajmer, India. Total 303 newborn subjected for this study. Out of these 189 newborn enrolled as control group for this study. Enrolment of sample was simple as our convenience during the study period. Results: Mean umbilical cord diameter was found smaller in newborns which associated with antenatal risk factors as compared to controls without antenatal risk factors (cases: 9.89 ± 2.53 mm; controls: 10.56 ± 2.26 mm) and the difference was statistically significant (P = 0.03). Oligohydramnios and meconium-stained liquor were found to be associated with the smaller umbilical cord diameter (P < 0.01). Conclusions: Oligohydramnios and meconium-stained liquor were found to be significantly associated with the thin umbilical cord.

“…They also showed that there was a poor fetal outcome in 50 pregnant women whose umbilical cord diameter was below the average in the first and second trimesters. [14] Proctor et al investigated the relationship between umbilical cord diameter and fetal weight in 497 pregnant women at 18-41 weeks of gestation. They showed a positive correlation of umbilical cord diameter with birth weight and placental weight.…”

Objective This study investigated the relationship between umbilical vein diameter and cord length and fetal outcome in low-risk pregnancies (fetuses appropriate for gestational age [AGA]). Methods A prospective cohort study of 39 singleton pregnant women aged 19–44 years at between 38+0 and 41+6 weeks of gestation was conducted. Case demographics, umbilical vein diameter measured by prenatal ultrasound, postnatal birth weight, gender, 1- and 5-minute Apgar scores, blood gas analysis, and umbilical cord length were recorded. Fetuses with a fetal weight in the 10–90th percentile according to week of gestation were accepted as AGA. Results The mean age of the pregnant women was 27.5±5.3 years. 33% (13/39) of the pregnant women were nulliparous. There was no statistically significant correlation between umbilical vein diameter and other variables in correlation analysis (p>0.050). Umbilical cord length and umbilical vein lactate level were found to have a statistically negative and significant correlation (r=-0.418; p=0.015); however, no other pregnancy outcomes were found to have a significant correlation. There was no statistically significant difference between the median values of umbilical vein diameter and cord length by gender (p=0.076 and 0.181, respectively). Conclusion In conclusion, this study found no relationship between umbilical vein diameter and cord length and fetal weight and pregnancy outcome in low-risk 38.0–41.6-week pregnancies (AGA fetuses). However, the obtained results still need to be confirmed by larger series.
