妊娠高血压综合征(简称孕高症,下同)旧名为妊娠中毒症。自古以来就知它对母儿的威协很大。尽管研究不断深入,但在发病的机理上仍有许多问题,尚未解决。由于在它的基本病理生理已经明确,在临床处理方面不断有了改进,不仅注重母体的治疗,也重视了对胎儿监测管理。一、孕高征时子宫胎盘循环缺血对胎儿的影响孕高征时的子宫血液循环低下是发病机制的“因”,又是病程中的“果”。子宫血液量减少,减少了对胎盘的供血,形成了子宫胎盘循环之缺血状态。可见在底脱膜与胎盘结合部的小动脉管壁退行性变,管腔狭窄、闭锁,绒毛间腔变小,以及绒毛间血栓,说明绒毛间腔内血流量之减少。肉眼上也 Pregnancy-induced hypertension (referred to as gestational hypertension, the same below) formerly known as gestosis. Since ancient times it knows that it is a great threat to the mother and child. Despite the deepening of the research, there are still many problems in the pathogenesis of the disease that have not yet been solved. Because of its basic pathophysiology has been clear, in clinical treatment has been improved, not only focus on the treatment of the mother, but also attached importance to the management of fetal monitoring. First, the pregnancy syndrome when the uterus placenta ischaemia fetal impact on the fetus Pregnancy and hypovolemia low uterine blood circulation is the pathogenesis of “cause” is the course of “fruit.” Uterine blood volume decreased, reducing the supply of blood to the placenta, forming a uterine circulation of the ischemic state. Can be seen in the bottom of the conjunctiva with the placenta in the arteriole wall degeneration, stenosis, atresia, villus cavity smaller, and villus thrombus, villus cavity blood flow reduction.
