Acute atherosis, early

I was looking at membranes from a mother with preeclampsia, and I guess I was just paying more attension, but certainly looks like the endothelium is lifted in the spiral arteries. In the first photograph there is even a small area of darker, fibrinoid appearing, condensation. This does not prove that acute atherosis is a lesion of increased endothelial permeability, but it does support the idea. There was acute atherosis in other arteries.
