Lesions of uteroplacental circulation (abruption, extensive infarction/thrombosis, basal or perivillous fibrin deposition, ↑syncytial knots) inversely related to membrane & cord inflammation. Earlier GA favored inflamm; older age favored charact of ↓blood flow. Inflammation of chorionic plate in 43%, cord in 19%, & chorionic plate vessels in 30%. Of placentas w/umb cord inflammation, 8% had no inflammation of chorionic plate.
