B型超声测量胎儿股骨皮下组织厚度预测胎儿体重

目的探讨应用Ｂ型超声测量胎儿股骨皮下组织厚度预测胎儿出生体重的临床价值。方法应用Ｂ型超声对１７８例胎儿的双顶径、头围、腹围、股骨长、股骨皮下组织厚度进行测量并与新生儿出生体重的关系进行分析。结果股骨皮下组织厚度与新生儿出生体重相关性最好（ｒ＝０．８６０１）,对巨大儿诊断的敏感性为９１％,特异性为９４％,胎儿股骨皮下组织厚度与孕周呈正相关（ｒ＝０．７０７０）。结论应用Ｂ型超声测量胎儿股骨皮下组织厚度预测胎儿出生体重,方法简单、准确,有较好的临床应用价值。

Ultrasonic measurements of fetal thigh soft tissue thickness in the estimation of fetal weight

Objective To study ultrasonic measurement of fetal thigh soft tissue thickness in the estimation of fetal weight. Methods Fetal biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and fetal thigh soft tissue thickness (FTSTT) were measured by ultrasonography and analyzed with neonatal birth weight in 178 cases. Results There was significant correlation between FTSTT and neonatal birth weight ( r =0.860 1), and it is better to estimate fetal weight with FTSTT than with the other parameters. The sensitivity and specificity for detection of macrosomia was 91% and 94%, respectively. The FTSTT was positively correlated with gestational age ( r =0.707 0). Conclusion The ultrasonic measurement of FTSTT is a simple, accurate and valuable index in estimation of fetal weight.
