Comprehensive dynamic examination of 27 patients after removal of basal meningiomas revealed some characteristic changes in the results of REG and EEG and in the neurological status. It was also found that the dynamics of the data studied differed with the course of the postoperative period. Some EEG and REG data of favourable prognostic importance were noted.

Their possible pathophysiological mechanisms, due to the effect of the tumor and operative injury to the hypothalamo-diencephalic apparatus are discussed.

The stroke blood volume and the MBV were determined by tetrapolar rheocardiography at rest and under the effect of muscular exertion in neurosurgical patients (35), in surgical patients (20) and in a control group of healthy subjects (10). A Soviet device, the Ppigamma2-02 tetrapolar rheocardiograph was employed. The method of tetrapolar rheocardiography is simple, atraumatic and provides for prolonged continuous recording.
