A preterm infant had an amniotic band sequence. Anomalies included left leg amputation and digital anomalies of the hands. The umbilical cord was short, and histologic sections of the placenta demonstrated partial avulsion of the amnion and fibrosis of the underlying chorion. Ultrasound at 21 weeks was normal, there was no history of trauma during the pregnancy, and no amniocentesis had been performed. Despite isolated case reports of amniotic band sequence associated with amniocentesis, we doubt that amniotic band formation is a significant risk after second-trimester amniocentesis.
一名早产儿患有羊膜带序列征。异常情况包括左腿截肢和手部手指异常。脐带较短，胎盘组织学切片显示羊膜部分撕脱以及其下绒毛膜纤维化。孕21周时超声检查正常，孕期无外伤史，未进行过羊膜腔穿刺术。尽管有孤立病例报告称羊膜带序列征与羊膜腔穿刺术有关，但我们怀疑孕中期羊膜腔穿刺术后羊膜带形成并非重大风险。
