Background: Macrosomia is an obstetric problem with maternal and neonatal adverse outcomes that
are associated with a high rate of perinatal morbidity and mortality. The aim is to assess the accuracy of
predicting fetal macrosomia by measuring the cross‐sectional area of the umbilical cord and the central
placental thickness at cord insertion by ultrasound.
Design: A prospective cross‐sectional study was performed at Banha University Hospital among 60 pa‐
tients coming into labor from January to June 2024.
Method: Trans‐Abdominal Sonography was done to measure fetal biparietal diameter, femur length,
abdominal circumference, the central placental thickness (PT) at cord insertion in mm, mean umbilical
cord cross‐sectional area (UCA), and ultrasonically estimated fetal weight. Mode of delivery, use of instru‐
mentation, actual fetal weight, shoulder dystocia, Apgar scoring, and neonatal outcome were recorded
