title: Morphology of placental villi and development of hemorrhages in very small preterm newborns.
abstract: We performed a comparative morphometric and immunohistochemical studies of the placentas collected in preterm labor after 27-33-week gestation. Predominating branched angiogenesis processes and more pronounced vascularization of the placental villi were found in the group of newborns with hemorrhagic complications. These changes were paralleled by high expression of VEGF in all villous structures.
