规范产前超声检查诊断胎儿肢体畸形的价值

of standardized prenatal ultrasonography in diagnosis of fetal limb deformities

目的：探析规范产前超声检查在诊断胎儿肢体畸形中的应用效果及其临床价值。方法选择驻马店市中心医院2010年9月至2013年9月294例行常规产检孕妇，均行超声检查，将超声检查胎儿肢体畸形种类、孕周情况与实际引产结果进行对比，以明确其临床应用价值。结果294例孕妇中共检出22例肢体畸形胎儿，实际引产结果畸形胎儿共24例，发生2例漏诊，确诊率达到91.7%。其中四肢短小、足内翻、肢体姿势异常、手缺如、挠骨缺如等的检出率均达到100%，仅多（并）指、趾类型畸形胎儿出现2例漏诊，检出率为60.0%。胎儿四肢畸形确诊孕周以18~32周为佳，检出率100%，〈18周及〉32周容易发生漏诊情况。结论规范产前超声检查在胎儿肢体畸形诊断中的应用可及时发现胎儿肢体畸形问题，可有效提高新生儿质量，具有较大临床价值，可作为胎儿质量筛查与控制的重要手段，对于实现优生优育意义重大。

Objective To evaluate the clinical value of standardized prenatal ultrasonography in diagnosis of fetal limb deformities. Methods Two hundred and ninety-four pregnant women were implemented of standardized prenatal ul-trasonography. Types of fetal limb deformities and gestational weeks diagnosed by standardized prenatal ultrasonography were compared with the real situation. Results Fetal limb abnormality was detected in 22 cases pre birth and there were 24 cases with fetal limb deformities in reality, the prevalence was 91. 7%. The prevalence of short limb abnormality, tali-pes varus, limb posture abnormalities, radial deficiency and hand absence were 100%. Two cases with multiple fingers （ toes） were missed diagnosed and the diagnosing accuracy was 60. 0%. The appropriate gestational age of diagnosing limb deformities was 18 to 32 weeks and the diagnosing accuracy was 100. 0%. The missed diagnosis was likely to happen when the gestational age was below 18 weeks or more than 32 weeks. Conclusions Standardized prenatal ultrasonography has great clinical value in the diagnosis of fetal limb deformities and the implement of prepotency.
