[Intraventricular hemorrhages: a nosological entity of the perinatal period].

186 autopsy observations of newborns (fetuses) with hemorrhages in the basin of the great cerebral vein of varying intensity and location were examined. Massive intraventricular hemorrhages (IVH) with tamponage and dilatation of the ventricles produce clinically neurological symptoms: adynamia, areflexy nystagmus, tremor. The etiology and pathogenesis of the disease have been sufficiently described, are peculiar and due to anatomo-physiological preconditions the leading role among which belongs to metabolic changes caused by hypoxia of the fetus, and regional hypertension in the great cerebral vein system particularly markedly manifest in precipitated and rapid parturitions, and in operative interventions. Thus, in massive IVH there is the totality of signs allowing this pathology to be considered as a distinct nosological form of the perinatal period.
