[Analysis of several causes of inadequate surgical treatment of epilepsy].

From the analysis of 100 cases with stereotaxic and "classical" surgical treatment of epilepsy several premises are drawn. The source of possible errors in the topical diagnosis of an epileptic focus may be overestimation in some case of the results of routine neuroradiological examination, and the possibility of the existence of reciprocal interrelationship of the epileptic foci and the activation of one of them in removal of the other. The authors suggests a method of control over the activity of intact foci after removal of the dominating elements of the epileptic systems. Some doubt is expressed concerning the diagnostic value of control (i. e. after removal of the focus) ECG examination and the conviction is stated for the need of widen the volume of single-stage stereotaxic operations by combining the destruction of the most active elements of the epileptic systems.
