胎儿羊膜带综合征的超声诊断

Ultrasonic diagnosis of amniotic band syndrome in fetus

目的探讨羊膜带在产前诊断中的意义，发现羊膜带综合征所致的胎儿畸形，为产前咨询和临床处理方案的选择提供有价值的参考资料。方法回顾性分析13例经尸解或引产后追踪证实的胎儿羊膜带综合征声像图资料，重点分析羊水暗区内漂浮光带的来源、性质，胎儿畸形的部位、程度，漂浮光带是否与胎儿畸形部位粘连。总结胎儿羊膜带综合征的超声诊断特点及鉴别诊断，分析漏诊、误诊的原因。结果羊膜带综合征共13例，产前超声确诊9例，多发畸形7例，单发畸形2例；漏诊2例；误诊2例。结论超声能清晰显示羊膜带的形态，并能检出粘连所致的胎儿畸形类别，从而对胎儿羊膜带综合征作出准确的产前诊断，对选择临床处理方案及降低同产期死亡率具有重要意义。

Objective To explore the significance of amniotic band in prenatal diagnosis, to find fetal abnormalities caused by amniotic band syndrome, and to provide valuable reference for prenatal counseling and for choice of clinical management. Methods The ultrasonic data on 13 cases of amniotic band syndrome confirmed by autopsy or examination after induced labor were retrospectively analyzed. The sources and features of floating band in the amniotic fluid dark areas, the location and extent of fetal abnormalities, and the adhesion of the floating band with the abmoral parts of the futus were analyzed. The reasons for missed diagnosis and misdiagnosis were determined by analyzing the ultrasonic features and differential diagnosis of amniotic band syndrome. Results 9 of 13 cases of amniotic band syndrome were confirmed by uhrasound, 7 of which were muhiple abnormalities and 2 were single. 2 cases were not diagnosed and 2 were misdiagnosed. Conclusions Ultrasonic examination can accurately detect amniotic band syndrome by clearly revealing the shape of amniotic band and the types of abnormalities caused by adhesion. It is of important significance in the selection of treatment plans and the reduction of perinatal mortality.
