Maternal medicine: Morphometric placental villous and vascular abnormalities in early‐ and late‐onset pre‐eclampsia with and without fetal growth restriction

Abstract

Isolated early-onset PET was associated with abnormal placental morphology, but placentas from late-onset PET were morphologically similar to placentas from gestational-age-matched controls, confirming the existence of two subsets of this condition and supporting the hypothesis that late-onset PET is a maternal disorder and not a placental disease.
