妊高征（ＰＩＨ）是产科的严重并发症，直接损害胎盘和影响胎盘功能，是导致孕妇产妇死亡及围产儿死亡的主要原因之一。ＰＩＨ的基本病理是全身小血管的痉挛，其血液动力学的表现为外周血管阻力增加，脏器灌流量下降。我们利用彩色多普勒血流显像技术观察子宫动脉血流参数的改?
Pregnancy-induced hypertension (PIH) is a serious complication of obstetrics, which directly damages the placenta and affects the function of the placenta. It is one of the main causes of maternal death and perinatal death in pregnant women. The basic pathology of PIH is systemic spasm of small blood vessels, whose hemodynamic manifestations include increased peripheral vascular resistance and decreased organ perfusion. We use color Doppler flow imaging to observe changes in uterine artery blood flow parameters?
