What are placental abnormalities of ecclampsia?

The morphologic changes of preeclampsia and eclampsia are variable and correlate to some degree with the severity of the disorder. Placental abnormalities include • Infarcts, which can be a feature of normal pregnancy, but are much more numerous with severe preeclampsia or eclampsia • Retroplacental hemorrhages • Premature maturation of placental villi associated with villous edema, hypovascularity, and increased production of syncytial epithelial knots • Fibrinoid necrosis and focal accumulation of lipid-containing macrophages (acute atherosis) of decidual vessels
