Birth Weight Prediction for Ultrasonic Measurement of Fetal Thigh Soft Tissue Thickness / 中国医师杂志

ABSTRACT

Objective To evaluate ultrasonic measurement of fetal thigh soft tissue thickness in the estimation of fetal weight . Methods Fetal biparietal (BPD), head cirumference (HC), abdominal cirumference (AC) , femur length (FL) and fetal thigh soft tissue thickness (TSTT) were measured by ultrasonography in 196 pregnant women during five days before dilivery and the relation with neonatal birth weight were analyzed.Results There was significantly correlation between TSTT and neonatal weight (r=0.865) , and it was better to estimate fetal weight with TSTT than with the other parameters. The prospective study showed that the predictive value of fetal TSTT was 80 1%.Conclusions The ultrasonic measurement of fetal TSTT is a simple and valuable index in estimation of fetal weight. [
