  • The discussion to improve the curative effect of stereo electroencephalogram-guided radiofrequency thermocoagulation for refractory epilepsy

    ObjectiveTo preliminarily explore the damage effect of stereo electroencephalogram-guided radiofrequency thermocoagulation after increasing the number of electrodes in the epileptic foci.MethodsEight cases were included from 42 patients requiring SEEG from the Department of Neurosurgery of the Second Hospital of Lanzhou University during June 2017 to Jan. 2019, of which 6 cases were hypothetical epileptogenic foci located in the functional area or deep in the epileptogenic foci that could not be surgically removed, 2 patients who were unwilling to undergo craniotomy; added hypothetical epileptic foci Electrodes, the number of implanted electrodes exceeds the number of electrodes needed to locate the epileptic foci. After radiofrequency thermocoagulation damages the epileptogenic foci, the therapeutic effect is analyzed.ResultsIn 8 patients, the number of implanted electrodes increased from 1 ~ 6, with an average of (4±2.2), and the number of thermosetting points increased by 2 ~ 10, with an average of (7±3.1); follow-up (9±3.2) months, Epilepsy control status: 3 cases of Engel Ⅰ, 3 cases of Engel Ⅱ, 2 cases of Engel Ⅲ; 8 cases of epileptic seizure frequency decreased≥50%. There was a statistically significant difference in the frequency of attacks before and after thermocoagulation (P<0.05).ConclusionsIncreasing the lesion volume of the epileptic foci can obviously improve the efficacy of epilepsy. SEEG-guided radiofrequency thermocoagulation is an effective supplementary method for classical resection.
