Background:Fetal weight estimation
by ultrasound is an important factor in obstetrics; it is directly related to
the gestational age which helps to plan the mode of delivery and labor
management. Objective:to compare between fetal thigh circumference
(TC) and abdominal subcutaneous tissue thickness (SCT) in estimating
birthweight in term pregnant women. Patients and Methods: This
prospective cohort study was conducted at outpatient clinic or emergency room, Obstetrics and Gynecology Department, Faculty of Medicine, Ain Shams University
Maternity Hospitals from March 2022 until May 2023. During this study, 100 term pregnant females with gestational age
37-40 weeks attended El Demerdash Maternity
Hospital and scheduled for delivery either at outpatient clinic or emergency
room were enrolled, after consenting each of them. Basic
fetal biometry was performed by an expert and professional medical personnel to
ensure the accuracy of examination results. Fetal abdominal subcutaneous
thickness and fetal thigh circumference were measured for assessment of
gestational age and correlated with actual fetal body weight. In the current
study, three formulas; Hadlock, Vintzileos’ and SCT formula were correlated
with actual fetal body weight after birth.
