Multilobar resections in surgical treatment of medically intractable epilepsy.

Unlabelled: MATERIAL, METHOD: Authors present the results of surgical treatment in a series of 93 patients with medically intractable epilepsy and large epileptogenic foci, in whom multilobar resections have been performed. They constituted 13% of a group of 716 patients subjected to surgery due to drug resistant epilepsy in the period 1957-1996, in the Department of Neurosurgery, Medical University of Warsaw, Poland. Patients treated with multilobar resection constituted the group, characterised by the most severe course of epilepsy, so they usually had a long seizures' history at the time of operation (more than 10 years duration of the disease in 37% of patients), albeit they were qualified to surgery at a relatively young age (mean age at the time of surgery: 16-th year of life).

[Effect of cerebellar cortical electrostimulation on the frequency of epileptic seizures in severe forms of epilepsy].

The authors studied 14 patients with epileptic seizures occurring from one to about 20 daily despite monitored pharmacological treatment. Two pairs of silver, properly insulated electrodes were applied to the subtentorial surface of both cerebellar hemispheres through burr-holes. The cerebellar surface was stimulated once daily for 30 min to 1 hour with electrical current at 10 Hz, 1 msec, 1-7 V during 10 to 16 days.
