摘　　要：妊娠期肝内胆汁淤积症(intrahepatic cholestasis of pregnancy,ICP)是妊娠中晚期特有的并发症,主要危害胎儿,其发病机制尚不清楚,胎盘的病变不足以解释临床现象。近年研究发现,ICP患者母体高胆酸水平对胎儿脏器组织结构和功能的损害是围产儿死亡的重要原因。另外,ICP胎盘结构及功能改变,脐带因素及内分泌变化等也可导致胎儿发育受损及宫内缺氧。近年来有关胆汁酸对胎儿心、肺、脑、肝等重要脏器的毒性作用、ICP胎盘病理及血流动力学改变、胎盘血管及脐带血管因素和内分泌变化的研究有了长足的进展。Intrahepatic cholestasis of pregnancy （ICP） is an unique complication in pregnancy, which usually manifests in the second or third trimester, and mainly harms the fetus. Its pathogenesis is not yet dear, and placental pathological changes are insufficient to explain the clinical phenomenon.Recent studies had shown that the important cause ofperinatal deaths may be the damage to the placental structure and function caused by the high bile acid level. In addition, the change of placental structure and function, unbilical cord factors, and endocrine changes can also cause the fetal development and intrauterine hypoxia. In recent years related researches focus on the toxic effect of bile acid on fetus heart, lungs, brain, liver, and other important organs, the placental vascular pathology, hemodynamic changes, umbilical cord blood vessel factors and the endocrine changes.
