【摘要】 目的探讨产前采用超声检查在胎儿肢体畸形筛检中的诊断意义。方法选取600名妊娠16~40周的孕妇,从检测到成形胎儿开始,对所有孕妇定时进行产前超声检查,观察胎儿的畸形情况,分析胎儿胎位及生长状况,并与产后诊断结果进行比较,分析产前超声检查对胎儿肢体畸形诊断的优势。结果在本次研究中,产前超声检查发现8种胎儿肢体畸形,共11例,2例误诊,确诊率为84.6%。畸形胎儿中四肢短小、足内翻、手脚姿势异常及并指并趾较为常见。结论在中孕期对孕妇进行产前超声检查,能够尽早发现胎儿肢体畸形,诊出率高,值得临床推广应用。更多还原

【Abstract】 Objective To explore the diagnostic significance of ultrasonography in the antenatal screening of fetal limb deformity. Methods A total of 600 pregnant women within 16 to 40 weeks were selected. They had all received antenatal ultrasonography regularly since the detection of full fetus. Fetal deformity was observed and fetal position and growth condition were analyzed. The results were compared with postnatal diagnostic results, and the advantages of antenatal ultrasonography towards the diagnosis of fetal limb deformity were analyzed. Results In this study, 8 types of limb deformity were observed via antenatal ultrasonography, altogether 11 infants. 2 infants were missed diagnosis. The confirmed diagnosis rate was 84.6%. Among the deformed infants, shortening of the limbs, strephenopodia, abnormal hand and foot positions and syndactylia were commonly seen. Conclusion Antenatal ultrasonography for pregnant women during the second trimester helps detect the fetal limb deformity in a timely basis, which has a high diagnosis rate and is worthy of clinical promotion.更多还原
