Description:
Frozen samples of blood and urine will be kept for further study related to this project involving markers relevant to placental insufficiency that may be discovered in the future. A gross assessment of the placenta will be performed by weighing the disc with cord and membranes removed. Cord insertion, length, diameter, coiling, number of vessels, focal lesions, membrane color, thickness, translucency, attachment, disc dimensions, range of thickness, fetal surface vascular distribution, pigmentation and site of rupture will be recorded. Microscopic assessment of H\&E stained sections will be performed to detect any inflammatory/infectious processes, villous development/maturity, decidual vasculopathy, infarct/fibrin deposition, or other processes that may be associated with placental insufficiency and fetal development.
