羊膜粘连带阻断序列征羊膜粘连带阻断序列征 临床特征为：畸形具多形性，多属羊膜粘连带阻断序列征，是羊膜破裂形成的纤维带缠绕胎儿体某部位，致该处发育受阻或成坏疽，造成的序列畸形。从指(趾)一小缩窄环到多发严重畸形。严重时指(趾)或四肢可完全截断。亦有多指(趾)，并指(趾)，畸形足，脊柱侧弯等；②头面部畸形：约1/3患儿有颅骨部分缺失、无脑畸形、脑膨出、小脑畸形，不规则唇腭裂，无眼，不对称性小眼等；③其他如胸腹裂、脐膨出、脊柱畸形。脑神经缺失、心血管异常、食管气管瘘、副脾等少见。产前B超见胎儿肢体截断，或不对称性畸形时，应疑有此征。出生体检时应注意局部有无羊膜粘连带或碎片状羊膜组织粘连插入胎儿体。认为孕母在绒毛取样，羊膜腔穿刺受伤或病毒感染造成羊膜破裂，羊水渗漏时，可发生上述畸形，其类型及严重程度与羊膜破裂的时间有关，破裂越早，畸形越严重。
