Abstract
Purpose. – Hypertension occurs in 10 to 15 p cent of pregnancies. Among them, 10 to 20% also have proteinuria. This situation defines preeclampsia, and involves a serious threat on fetal and even maternal prognosis. Presence of the hepatic (HELLP) syndrome still severely worsens the prognosis. Current knowledge and key points. – Pathophysiology of preeclampsia is based on a very early abnormality of placentation, leading to insufficient blood supply to the feto-placental unit. At the maternal level, the main consequence of placental ischemia is generalized endothelial dysfunction, responsible for systemic vasoconstriction and clotting abnormalities. In such a context, lowering blood pressure with drugs is quite inefficient, or even harmful. The prognosis of this disease is mainly related to the pertinence of obstetrical management. Future prospects and projects. – An early preventive strategy is the most logical approach of preeclampsia, its modalities remain under discussion.
