The given study aimed to answer the question about the realization in clinical practice of the possibility of the timely identification of the degree of intracranial hypertension in patients with cerebral stroke under continuous monitoring of the intracranial volume/pressure ratios by means of examination of CSF changes and CT of the head. On the basis of an analysis of the interrelationship between the severity of neurologic deficit, findings of CT of the head and the results of examination of the cerebral hemodynamics the authors evaluated the informativeness of the main parameters of monitoring the intracranial volume/pressure ratios in the acute stage of cerebral stroke. It has been found that only prolonged registration of the mean and pulse pressure of the CSF in combination with "testing the reserve of the intracranial volume" may ensure the timely detection of disorders of the homeostasis of the craniospinal reservoir and the selection of the most effective means of their correction.
