title: [Complex study of the hemodynamics, impedance, and bioelectrical activity of the brain of patients with parasagittal meningiomas].
abstract: Combined use of radioisotope and impedance methods in the examination of cerebral and peripheral circulation and EEG recording in 40 patients with parasagittal meningiomas revealed a correlation between the rheographic characteristics of the tonus and blood filling of the cerebral vessels and the quantitative values of cerebral hemodynamics. Specific features of cerebral circulatory disorders characteristic of parasagittal tumors were revealed before operation and in the postoperative period. The prognostic significance of examination of the cerebral blood flow and impedance in the early postoperative period is demonstrated.
