Preeclampsia Stages

The two-stage model of pre-eclampsia, originally proposed more than a decade ago (Redman, 1991) and described elsewhere in this volume, envisages that pre-eclampsia arises in various ways including from placental ischemia secondary to deficient placentation. Whereas some consider abnormal placentation to be the start and invariable cause of pre-eclampsia, it is much more likely that it is a completely separate but predisposing condition (Redman and Sargent, 2000). Placentation is described...

Diagnosis of superimposed preeclampsia in chronic hypertension renal disease and diabetes

In contrast to gestational hypertension and preeclampsia that occur in the second half of pregnancy, hypertension that is evident before 20 weeks' gestation is diagnosed as chronic hypertension. The Australasian and American classifications are consistent in their definitions of chronic hypertension, blood pressure > 140 mmHg systolic and or > 90 mmHg diastolic pre-conception or in the first half of pregnancy (Anonymous, 2000 Brown et al., 2000). Rare exceptions include hydatidiform molar...
