What is pathogenesis of preeclampsia?

Pre-eclampsia is characterized by defective placentation, placental ischaemia, abnormal spiral artery remodelling, oxidative stress at the maternal–fetal interface and angiogenic imbalance in the maternal circulation with ensuing endothelial and end-organ damage.

What is difference between preeclampsia and eclampsia?

Preeclampsia and eclampsia are pregnancy-related high blood pressure disorders. Preeclampsia is a sudden spike in blood pressure. Eclampsia is more severe and can include seizures or coma.
