Abstract
Background: In utero estimation of fetal weight is an important component of management of pregnancy. It provides valuable information which aids the physician to take informed decisions concerning the timing and route of delivery. Fractional thigh volume can be added to two-dimensional sonographic measurements of the head and trunk to improve the precision of fetal weight estimation. This approach permits the inclusion of soft tissue development as part of a weight estimation procedure. The aim of this study to detect the accuracy of fetal thigh volume in prediction of fetal weight.
Objective: Detection the accuracy of fetal thigh volume in estimation of fetal weight in comparison to the gold standard method (hadlock’s formula) and comparing it with the actual birth weight after delivery.
Patients and Methods: Our study was conducted in Ain shams University, maternity hospital/ultrasound unit from September 2022 to May 2023. This study was a cross-sectional study on 55 women who underwent delivery and fulfilled our inclusion criteria.
Results: There was statistically significant increase in the mean EFW by Hadlock’s formula (3192.35±488.46) than the mean actual birth weight after delivery (3024.36 ± 439.36) with mean difference of 167.98±461.97 and with p-value = 0.009. There was no statistically significant difference found between mean EFW by fetal thigh volume (3138.04±441.46) and mean actual birth weight after delivery (3024.36±439.36) with mean difference of 113.67±429.36 and with p-value = 0.055.
Conclusion: Estimation of fetal weight is a very important antepartum assessment. Fetal 3D-fractional Thiv is consistent with actual birth weight The Measurement of fractional thigh volume can improve the accuracy of fetal weight prediction in comparison to the conventional method using Hadlock’s formula.
