[Morphology of disorders of cerebral circulation in the white matter of the cerebral hemispheres in the newborn infant].

The author examined histologically the white matter of the brain hemispheres in 29 mostly immature children who died within 3 days after birth. The newborns were grouped by the following kinds of damage to the white substance of hypoxic and ischemic nature associated with disorders of the cerebral hemodynamics: endemous-hemorrhagic leukoencephalopathy (EHL), periventricular telencephalic gliosis (PTG), periventricular leukomalation (PL), periventricular hemorrhagic leukomalacia (PHL) and cerebral hematomas. Certain similarity in the topography of lesions in EHL, PHG, PL and PHL was established. The most considerable lesions were found in the periventricular white substance of the initial portions of the posterior corns.
