Assessment of Accuracy of two dimensions ultrasonography of fetal thigh soft tissue versus Hadlock's formula in estimation of fetal weight: Comparative study

Abstract

ltrasound is now widely used in routine antenatal care for pregnancy dating and location, screening for aneuploidy, fetal anomaly screening, determining chorionicity in multiple pregnancy, and placental localization. The use of ultrasound is well established in assessing fetal growth and wellbeing, amniotic fluid volume, and cervical length. The aim of this study is to compare the accuracy of different sonographic formulae for fetal weight estimation. Two hundred full term pregnant women were included in this study. Their gestational age was between 38-40 weeks. Approval from the Medical Ethics Committee was obtained. Informed verbal consent was obtained from all patients. At the time of recruitment, one of the study investigators approached all eligible participants for obtaining detailed history taking; maternal age, gestational age, parity, and past medical history. Additionally, they subjected to general examination, abdominal examination (as regard fundal level, lie of the fetus, detection of any uterine contractions and fetal heart rate).
