目的:探讨羊膜带引起胎儿畸形的超声诊断特点和临床价值,以提高产前诊断率。方法:选取2008年6月至2012年6月我院明确诊断为羊膜带综合征的4例患者进行回顾性分析,观察超声诊断特点。结果:羊膜带综合征造成的胎儿畸形主要有3类:肢体畸形、颅裂面裂和腹壁缺损等;通过超声检查首先发现胎儿畸形,其中最明显的为腹裂、脑膨出等,其次在畸形区域发现异常光带。结论:羊膜带能够引起胎儿畸形,超声诊断能够清晰的显示羊膜带的形态、胎儿畸形的类型,对诊断羊膜带综合征有着重要的临床价值。
Objective: To investigate the characteristics and clinical value of ultrasonic diagnosis of fetal malformation caused by amniotic membrane in order to improve the rate of prenatal diagnosis. Methods: A retrospective analysis was performed on 4 patients with amniotic band syndrome diagnosed in our hospital from June 2008 to June 2012, and the features of ultrasonic diagnosis were observed. Results: There were three main types of fetal malformations caused by amniotic band syndrome: limb deformity, cracked craniofacial fissure and abdominal wall defect. Fetal malformations were found by ultrasonography first, of which the most obvious were astrocytosis and encephalocele, Deformed area found abnormal light band. Conclusion: The amniotic membrane can cause fetus deformity. Ultrasonography can clearly show the shape of amniotic membrane and the type of fetus deformity. It has important clinical value in the diagnosis of amniotic band syndrome.
