title: [Value of rheographic studies in the diagnosis of epileptogenic foci in temporal lobe epilepsy].
abstract: Using a type II Siemens rheograph 100 patients with temporal lobe epilepsy aged 18--36 years were investigated. In each case rheographic investigation was done in sitting and lying position, at rest and after hyperventilation in both these positions. The shape of the descending arm of the main wave of the averaged rheoencephalographic curve was analysed in detail. In 89 cases unilateral presence of h1 wave was found, which was absent in the rheograms of healthy subjects, and h2 wave was present also. The shape of the remaining rheographic curves in this population was not different from the records obtained in healthy subjects. In 92 patients EEG investigations demonstrated focal changes were found, in 8 bilateral changes were present, prevalent on one side. In 85 cases h waves were present on the side of the epileptogenic focus, and in 4 cases it was present contralaterally but only in patients with bilateral EEG changes. The results of these investigations point to differences in the haemodynamic conditions in the temporal lobes in healthy subjects and in most patients with temporal lobe epilepsy on the side of the epileptogenic focus. Rheographic investigations was found to be useful for determination of the side of the epileptogenic focus.
