Prof: Kavitha Mole PJ 3/28/2017 2 3. Five to 7% of all pregnancies are complicated by preeclampsia. INTRODUCTION 3/28/20173 4. The maternal effects of severe disease may involve multiple organ systems. The pathophysiology of these conditions, however, remains poorly understood, limiting therapeutic interventions. Preeclampsia is a unique, complicated problem of pregnancy that is prevalent worldwide. The critical role of the placenta in the pathophysiology of preeclampsia, particularly early onset-preeclampsia, is supported by epidemiologic and experimental data that show: Placental tissue is necessary for development of the disease, but the fetus is not .

Preeclampsia is a systemic vascular disorder characterized by new-onset hypertension and proteinuria after 20 weeks of gestation. DEFINITION DEFINITION: Preeclampsia is a multiple system disorder of unknown etiology characterized by development of hypertension to the extent of 140/90 mm hg or more with proteinuria after 20th week in a previously normotensive and non-proteinuric woman. It has been suggested that preeclampsia is a two-stage disease (1). Pathophysiology of Hypertension in Preeclampsia Introduction Preeclampsia is a hypertensive disorder of pregnancy, classically it is defined as the onset or worsening of hypertension in pregnancy and proteinuria of at least 300 mg in 24 hours. Pre-eclampsia (PE) is a disorder of pregnancy with a worldwide prevalence of about 5–8%. Author information: (1)Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, Massachusetts 02215, USA. Factors may include poorly developed uterine placental spiral arterioles (which decrease uteroplacental blood flow during late pregnancy), a genetic abnormality on chromosome 13, immunologic abnormalities, and placental ischemia or infarction. Hypertensive disorder specific to pregnancy ; affects nearly 6 of all pregnancies ; a major cause of maternal and neonatal mortality and morbidity ; 15 to 20 of maternal mortality in developed countries ; 3 PREECLAMPSIA. Proteinuria and hypertension dominate the clinical picture, because the chief target organ is the kidney (glomerular endotheliosis). It is clinically defined by hypertension and proteinuria, with or without pathologic edema. Pathogenesis of preeclampsia. • Incidence lies between 5-10% and is gradually increasing. PRE-ECLAMPSIA 2.
