绒毛膜羊膜分离可分为生理性与病理性,妊娠14周前为生理性分离,妊娠14周及以后则为病理性分离。胎膜损伤是导致病理性绒毛膜羊膜分离的主要原因,介入性宫内诊断或干预都要经过子宫肌层及羊膜腔,导致胎膜损伤,范围较小的绒毛膜羊膜分离无临床意义,范围较大的明显增加胎膜早破、感染、早产、羊膜带综合征和胎死宫内的发生率,目前尚无有效的预防及治疗方法。少部分病理性绒毛膜羊膜分离是自然发生的,与基因突变或染色体非整倍体有关,预后不良,应终止妊娠。
Chorionic amniotic membrane separation can be divided into physiological and pathological, physiological separation 14 weeks before pregnancy, 14 weeks after pregnancy and pathological separation. Membrane damage is the leading cause of pathological chorion amniotic membrane separation, interventional intrauterine diagnosis or intervention must go through the myometrium and amniotic cavity, leading to fetal membrane damage, a small range of chorionic amniotic membrane separation of no clinical significance, scope Larger significantly increased premature rupture of membranes, infection, premature birth, amniotic band syndrome and the incidence of fetal death, there is no effective prevention and treatment. A small number of pathological chorionic amniotic membrane separation is a natural occurrence, and genetic mutations or chromosome aneuploidy, the prognosis is poor, should terminate the pregnancy.
