Fetal Weight Prediction by Thigh Volume Measurement with Three-Dimensional Ultrasound
Suzan Jomaa Mohammed Modade;
Abstract
Estimation of fetal weight is essential in daily obstetric practice, before delivery or at third trimester for women with potential risk of intrauterine growth restriction (IUGR) or macrosomia. It guides obstetricians to make up their decisions as regard time and mode of delivery to guard against complications of low birth weight (LBW) and macrosomic babies during labor and puerperium .
The Perinatal complication associated with low birth weight are most often attributable to fetal prematurity, but may sometimes arise as a result of intrauterine growth restriction.
Perinatal complications associated with macrosomic fetuses include shoulder dystocia, brachial plexus injuries, bony injuries and intrapartum asyphaxia, as well as maternal risk that include birth canal injures, pelvic floor injuries and post partum hemorrhage .
The present study was conducted at Ain Shams University Maternity and Women’s Hospital, including 170 pregnant patients in a period from January 2013 till July 2013. the study was performed in cooperation with "the feto-maternal Unit for ultrasound assessment in the university maternity hospital at Ain-Shams Faculty of Medicine after respecting certain inclusion and exclusion criteria.
Both two-dimensional and three-dimensional ultrasound examinations was performed to the study group, most patients were admitted for an elective cesarean delivery for obstetric indication. All the fetuses were delivered within 48 hour after the ultrasound examination.
The current study compared Hadlock formula which represents use of 2D US using BPD, FL & AC in predicting fetal birth weight with Song et al formula which uses total modified thigh volume to predict fetal birth weight by the aid of 3D US.
Categorical analysis (Chi-Square) of the percent of the absolute error in the Estimated Fetal Weight by 2D ultrasound (3184.18±513.92 grams) among the studied fetal group was 7.73±674. While, EFW by 3D ultrasound (3089.82±553.70 grams) in the studied group was 4.20±7.67.
Analysis of Variance (ANOVA) of the difference of absolute errors in the measurements of the EFW (by grams) of the 2D and 3D ultrasound (X2 = 20.545) showed the highly significant difference (P <0.001).
In the present study, the highly significant positive correlation (P <0.001) between the actual fetal body weight (in grams) and the EFW (by grams) by both 2D (r = 0.864) and 3D ultrasound (r = 0.934) and the Modified thigh volume (r = 0.933) of the fetal outcome was demonstrated.
