Pathophysiology Likely due to vasogenic edema secondary to an acute increase in arterial blood pressure which overwhelms the autoregulatory capacity of the cerebral vasculature causing arteriolar vasodilation and endothelial dysfunction leading to extravasation of fluid ie preeclampsia Thackeray and Tielborg 2007. Theyre narrower than normal blood vessels and react differently to hormonal signaling which limits the amount of blood that can flow through them. 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.
