| ［摘要］ 目的 探讨超声对胎儿畸形的诊断价值及其局限性。方法 回顾性分析22例胎儿畸形的临床资料，并对产前超声诊断为胎儿畸形的声像图特点进行分析。结果 22例胎儿畸形中：单发畸形15例（68.2%）、复合畸形3例（13.6%）、多发畸形4例（18.2%），所有病例均经正常分娩或引产后尸检证实，产前超声诊断与产后完全符合19例（86.4%），漏诊3例（13.6%）。结论 超声可实时观察宫内胎儿各器官发育情况，不仅能确定胎儿有无畸形，而且能对胎儿畸形的类型明确诊断，对临床有重要的诊断价值，但也有其局限性。 |

| ［Abstract］ Objective To explore the value and limitation of ultrasonography in the diagnosis of fetal deformities. Methods The clinical data of 22 fetues with deforminities were retrospectively analyzed and the ultrasonographic characteristics of fetuses with deformities that were diagnosed by prenatal ultrasonography were analyzed. Results Among 22 fetuses with deformities, single deformity were found in 15 fetuses(68. 2%), complex deformities in 3 fetuses(13. 6%), mutiple deformities in 4 fetuses(18. 2%). The deformities in 22 fetuses were proved by clinical examination after natural birth or by outopsies after induced abortion. Among 22 fetuses with deformities, the deformities were diagnosed by prenatal ultrasonography in 19 fetuses, the ultrasonographic diagnosis rate was 86. 4%; the deformities were not detected by prenatal ultrasonography in 3 fetuses, the ultrasonography missed diagnosis rate was 13. 6%. Conclusion The development status of feta organs can be visualized by ultrasonography. Ultrasonography can not only detect the presence of fetal deformities, but also can indicate the variety of deformities. It has important value in the diagnosis of fetal deformities, but there are also limitations in its clinical use. |
