[Phasic nature of intracranial hypertension in patients with parasagittal meningiomas].

Complex quantitative determination of the relationship of the cerebrospinal system viscoelastic properties and the CSF dynamics in the brain contributed to identification of the phase character of intracranial hypertension in patients with parasagittal meningiomas and to the disclosure of compensatory mechanisms which come into action during the development of intracranial hypertension. Pathophysiological analysis of the functional condition of these compensatory mechanisms may be of essential importance in deciding on the optimum terms for the surgical treatment of patients with parasagittal meningiomas and for prognosticating the results of neurosurgical operations.
