Pre-eclampsia is one of the most serious complications of pregnancy affecting 3-8 % of pregnancies worldwide. It is a multi-system disorder involving maternal vessels (causing hypertension and endothelial dysfunction), the kidneys, the liver, the lungs, the hematological system, the cardiovascular system and the feto-placental unit. In its most severe form, it affects the brain, causing seizures (eclampsia), cerebro-vascular events and even death.
