In preeclampsia, there occurs a defective trophoblastic invasion of spiral arteries, which is characterized by abnormal uterine artery wave parameter such as increased pulsatility index (PI) and early diastolic notch. This increased uterine artery PI is a good predictor of hypertensive disorder and small for gestational-age babies. Maternal hypertension and proteinuria resolve in the puerperium. Arterial Doppler changes in normal pregnancy were extensively studied. Doppler changes in uterine artery in hypertensive postpartum women were less researched and unclear. This review aimed to compare the uterine artery Doppler changes in preeclamptic and normotensive women during the puerperium through an extensive search of the available literature. It was found that even with the lengthiest follow-up of six weeks postpartum, the increased uterine artery PI persisted and the magnitude was higher in hypertensive than normotensive postpartum women.
在子痫前期，螺旋动脉发生滋养细胞浸润缺陷，其特征是子宫动脉波形参数异常，如搏动指数（PI）增加和舒张早期切迹。这种子宫动脉PI升高是高血压疾病和小于胎龄儿的良好预测指标。产妇高血压和蛋白尿在产褥期会消退。正常妊娠时动脉多普勒变化已得到广泛研究。产后高血压妇女子宫动脉的多普勒变化研究较少且尚不清楚。本综述旨在通过广泛检索现有文献，比较产褥期子痫前期和血压正常妇女的子宫动脉多普勒变化。结果发现，即使在产后最长六周的随访中，子宫动脉PI升高仍然存在，且高血压产后妇女的升高幅度高于血压正常的产后妇女。
