Abstract： 异位妊娠是指受精卵在子宫腔以外的地方着床,常见的植入部位包括输卵管、宫颈、卵巢、腹腔、阔韧带等.剖宫产术后子宫瘢痕妊娠(caesarean scar pregnancy,CSP)是一种较为少见的异位妊娠,其特点是受精卵着床于剖宫产的子宫瘢痕处,被纤维结缔组织包绕而与宫腔不相通[1-2].文献报道,妊娠妇女中CSP的发生率为0.045％,占所有异位妊娠的6.1％[3-4].1978年,Larsen和Solomon[5]首次描述了CSP,并认为其是导致流产后大出血的一种罕见疾病.近20年来,随着剖宫产率的升高,CSP的发生率也不断攀升,相关的文献报道也随之增多.然而,目前CSP的发病机制尚未完全明确,对其预防和治疗也缺乏针对性与前瞻性,许多临床工作者从不同的方向进行了大量有益的工作,现结合文献就CSP的发病机制综述如下.
