保守性缝合技术对凶险性前置胎盘保留生育功能的有效性临床分析
发布时间:2024-03-27 04:10
背景:Previa是拉丁语,意思是之前,因此前置胎盘即胎盘位于胎儿之前的产道里。前置胎盘定义为胎盘植入于子宫内口下方或内口附近的子宫下段。根据从胎盘边缘到内口的距离,前置胎盘分为四种类型:低置胎盘,边缘性前置胎盘,部分性前置胎盘和完全性前置胎盘。子宫蜕膜发育不良导致胎盘牢固附着,胎盘侵入子宫肌层称为胎盘植入。这是前置胎盘中最常见的并发症。在正常胎盘中,胎盘-子宫内膜边缘被纤维蛋白层(Nitabuch层)分开,它可以抑制胎盘过度植入子宫壁。纤维蛋白层随后产生解离面,从而允许胎儿娩出后自然发生第三产程。子宫内膜边界区纤维蛋白层和胎盘细胞滋养层的破坏可能导致胎盘异常粘连。当滋养层侵入包含连接绒毛膜绒毛与子宫肌层的基蜕膜的海绵层(Nitabuch)正常的临界以外的其他地方,就会发生胎盘植入。当绒毛膜绒毛侵入到子宫肌层时,称为胎盘植入。绒毛膜绒毛穿透子宫肌层,超越浆膜层,侵入膀胱和/或其他盆腔器官称为胎盘穿透。胎盘植入综合征是由胎盘异常植入引起的。前置胎盘的临床特征是突发,无痛,反复的阴道出血。无痛性阴道出血最常见于妊娠中期末或之后,但也可能在妊娠中期之前开始。在妊娠的后几个月,子宫下段形成。在...
