目的探讨产前超声在诊断胎儿十二指肠狭窄或闭锁中的诊断方法和应用价值。方法对近10年来在本站查出可疑胎儿十二指肠狭窄或闭锁的16名胎儿的超声检查资料进行回顾性分析,并与尸检或产后随访结果对照比较。结果超声诊断十二指肠狭窄或闭锁16例,经尸检及产后随访明确诊断的十二指肠狭窄或闭锁为15例,超声诊断准确率为94%,误诊1例。16例中14例合并羊水过多。结论产前超声在胎儿十二指肠狭窄或闭锁的产前诊断中有很高的应用价值,而且大部分十二指肠狭窄或闭锁都合并羊水过多。
Objective To investigate the diagnostic value and application of prenatal ultrasound in the diagnosis of fetal duodenal stenosis or atresia. Methods The ultrasound examination data of 16 fetuses with suspicious fetal duodenal stenosis or occlusion detected in our hospital during the past 10 years were retrospectively analyzed and compared with the autopsy or postnatal follow-up results. Results Ultrasound diagnosis of duodenal stenosis or atresia in 16 cases, autopsy and postpartum follow-up diagnosis of duodenal stenosis or atresia were 15 cases, the diagnostic accuracy of ultrasound was 94%, 1 case of misdiagnosis. Of the 16 patients, 14 had polyhydramnios. Conclusion Prenatal ultrasound has a high value in prenatal diagnosis of fetal duodenal stenosis or atresia, and most of the duodenal stenosis or atresia are associated with polyhydramnios.
