[The classification and topical diagnosis of cerebral circulatory disorders in newborn infants].

The classification of disorders of cerebral circulation (DCC) was presented on the basis of clinical-neurosonic study of 100 newborn children with the signs of DCC. There were-determined the same degrees of DCC severity as in hypoxic-ischemic encephalopathy (that is light, manifested, severe ones). There weren't observed any signs of focal damages of brain in light form of DCC, although there might sometimes be found the small ischemic damages of brain and injuries of hemorrhagic type in one third of patients. In manifested DCC there were revealed the signs of focal cerebral damages which were caused by combination of hemorrhages in choroid plexus of lateral ventricles and subependymal hemorrhages, and were rarer conditioned by ischemic necrosis of these regions. It was quite characteristic for severe DCC the appearance of pronounced total cerebral disorders just after the birth which might progradiently increase. There were found parenchymatous, subarachnoidal, and intraventricle hemorrhages by means of neurosonography. There was demonstrated the significance of investigation of both muscular tonus and reflexes in newborn children for topic DCC diagnostics.
