Efficacy of USG in Measurement of Umbilical Cord Thickness, Cross-Sectional Area and Coiling Index
Shishir Gupta

Introduction- The umbilical cord is a conduit between the developing embryo or fetus and the placenta. The present study was conducted to evaluate the value of umbilical cord thickness, cross-sectional area, and coiling index with Ultrasonography (USG). Materials & Methods: The present study was conducted in the department of Radiodiagnosis on 140 pregnant women who underwent USG. Gestational age was based on a reliable last menstrual period or the earliest USG examination before 20 weeks of gestation.   In all patients USG was performed using a 3.5-MHz convex transducer. Umbilical cord thickness, cross-sectional area, and coiling index were measured in a free-floating loop of umbilical cord using the software in the USG unit. Results- Mean gestational age at delivery was 38.65± 2.4 weeks, mean birth weight was 3456± 483 grams, low birth weight was seen in 24 children, meconium stained amniotic fluid was observed in 5 cases and there was no intrauterine death. Mean thickness of umbilical cord was 1.52, 10th centile was 1.3, 90th centile was 1.9, area was 1.92, 10th centile was 1.2, 90th centile was 2.8 and coiling index was 0.5, 10th centile was 0.25 and 90th centile was 0.56. Thickness <10th was 53%, 10-90th was 46%, area < 10th was 56%, 10-90th was 43%, coiling index <10th was 22% and 10-90th was 74% and >90th was 3%. Conclusion- Umbilical cord thickness and cross-sectional area are easy to measure in a free loop of umbilical cord and both are correlated with LBW and meconium staining in the second half of gestation. USG proves to be beneficial in uterine examination in pregnant women.
Key words- Coiling index, Ultrasonography, Umbilical cord.
