In some cases of drug-resistant focal epilepsy, noninvasive presurgical investigation may be insufficient to identify the ictal onset zone and the eloquent cortical areas. In such situations, invasive investigations are proposed using either stereotactic electroencephalography (SEEG) or subdural grid electrodes. Meta-analysis suggests that SEEG is safer than subdural grid electrodes, but insular implantation...
Objective
Stereo electroencephalography (SEEG)–guided radiofrequency thermocoagulation (SEEG‐guided RF‐TC) has been proposed since 2004 as a possible treatment of some focal drug‐resistant epilepsy. The aim of this study is to provide extensive data about efficacy and safety of SEEG‐guided RF‐TC.
Methods
Over a 10‐year period, 162 patients with drug‐resistant focal epilepsy were eligible for SEEG‐guided...
Deep brain electrodes have been used for the past 10 years to produce bipolar stereo-electro-encephalography−guided radiofrequency thermocoagulation (SEEG RF-TC). However, this technique is based on empiric knowledge. The aim of this study is 3-fold: 1) provide in vivo animal data concerning the effect of bipolar RF-TC on brain and its safety; 2) assess the parameters of this procedure (current delivery...
