Definition / general
  • Abnormal / incomplete remodeling of the spiral arteries resulting in necrosis (atherosis)
  • Observed in placentas from preeclamptic pregnancies as well as several collagen vascular / autoimmune disorders and in those with evidence of growth restriction (Arch Pathol Lab Med 1991;115:722)
Etiology
  • Associated with oxidative stress and endothelial dysfunction
Gross description
  • Placentas may be grossly unremarkable or may be small for gestational age
Microscopic (histologic) description
  • Lesions vary from nonnecrotic, nontransformed decidual arterioles to early fibrinoid necrosis of vessel walls and late atherosis (fibrinoid necrosis with subendothelial lipid laden macrophages)
  • Thrombi may be present
  • Some cases show marked hypertrophy of the media (hypertrophic decidual vasculopathy)
