四维超声诊断胎儿肢体畸形的应用探讨

Discussion of four-dimensional ultrasound in diagnosis of fetal limb deformities of the application

目的探讨应用四维超声诊断胎儿肢体畸形的临床价值。方法选取于2013年2月至2014年2月来我院接受治疗的胎儿肢体畸形孕妇23例作为研究对象,均采用四维超声诊断方法,对其临床资料予以回顾性分析。结果 23例产妇经引产后证实四维超声诊断结果有21例符合,准确率为91.30%,其余2例分别为疑诊(手畸形)与漏诊(指、掌缺失),各占4.35%。其中,有8例胎儿肢体畸形为马蹄足内翻,6例为四肢短小,肢体缺如和多指、趾以及桡骨发育不良或缺失分别为2例,指、掌缺失和手畸形以及指重叠则分别为1例。经研究后发现,胎儿肢体畸形主要影响因素有遗传(染色体异常)、环境因素、羊水过多以及胎儿姿势等。结论应用四维超声来诊断胎儿肢体畸形准确率较高,值得临床推广。

Objective：To investigate the clinical value of application of four-dimensional ultrasound in diagnosis of fetal limb deformity. Methods：In 2013 February to 2014 February in our hospital treated 23 cases of pregnant women of fetal limb deformity as the research object,adopt the method of four-dimensional ultrasound diagnosis,be a retrospective analysis of clinical data. Results：In the 23 cases confirmed by the induction of labor after 4D ultrasound diagnosis results of 21 cases met,the accuracy rate was 91.30%,the other 2 cases were suspected（hand deformity）and missed diagnosis（finger,palm deletion）,each accounted for 4.35%. Among them,8 cases of fetal limb deformity for talipes equinovarus,6 cases with short limbs,absence and multi finger,toe and radial hypoplasia or absence of respectively 2 cases,palm,finger and hand deformity and lack of fingers were 1cases. After the research discovery,the main influence factors of fetal limb deformities genetic（chromosome abnormality）,environmental factors,polyhydramnios and fetal position etc. Conclusion：The application of four-dimensional ultrasound in diagnosis of fetal limb deformity rate of accuracy is high,is worth the clinical promotion.
