【摘要】：目的探讨产前超声五趾-跖-跟骨足底平面在筛查胎儿足畸形中的价值。方法连续性选取10 015胎14~40孕周高危胎儿作为研究对象,产前超声检查采用五趾-跖-跟骨足底平面筛查足畸形,并与随访结果进行比较。结果胎儿足长随孕周增加而增大(F=8.2,P0.01),单纯先天性马蹄内翻足胎儿的患侧足长变短(χ2=49.1,P0.01)。五趾-跖-跟骨足底平面超声诊断胎儿足畸形准确率为99.60%(9975/10 015),敏感度为85.29%(116/136),特异度为99.80%(9859/9879),阳性预测值为85.29%(116/136),阴性预测值为99.80%(9859/9879)。结论五趾-跖-跟骨足底平面可用于胎儿足畸形的产前超声筛查,并可提高诊断水平。
[Abstract]:Objective to evaluate the value of prenatal ultrasound in the screening of fetal foot deformity. Methods 100 015 fetuses with 1440 gestational weeks were selected as the research objects. Antepartum ultrasound was used to screen foot deformity with fivetoe plantar calcaneal plantar plane and the results were compared with that of follow-up. Results the fetal foot length increased with the increase of gestational week (P 0.01). The foot length of the affected side of congenital equinovarus equinovarus fetus became shorter (蠂 2 49.1). The accuracy of ultrasonic diagnosis of fetal foot deformity was 99.60% (9975 / 10015). The sensitivity was 85.29 / 116 / 136, the specificity was 99.80 / 9859 / 9879, and the positive predictive value was 85.29 / 116 / 136). The negative predictive value was 99.809 / 9859 / 98790.Conclusion the plantar plantar plane of five-toe metatarsal and calcaneal bone can be used for prenatal ultrasound screening of fetal foot malformation and can improve the diagnostic level.

【正文快照】： 先天性足畸形种类繁多,产前诊断困难。研究[1]报道,马蹄内翻足(congenital talipes equinovarus,CTEV)的产前超声诊断率仅为25.5%。因此寻找一种简便的超声平面和指标诊断胎儿足畸形非常重要。本研究旨在探讨产前超声五趾-跖-跟骨足底平面在筛查胎儿足畸形中的价值。1资料与方
