Clinical Trial Summary

The aim of the study is to evaluate safety and efficacy of epilepsy surgery in the form of cortical resections in patients with refractory epilepsy and to review outcomes of resection procedures in focal epilepsy.

Clinical Trial Description

Nearly one-third of epilepsy patients are refractory/resistant to medical treatment . Refractory or drug-resistant epilepsy is defined as resistance to treatment with two appropriately chosen and tolerated antiepileptic drugs (AED) . Nevertheless, epilepsy surgery is an effective alternative treatment for some patients as it suggests seizure freedom . During the past 3 decades, surgery has found more acceptance as an option for drug-resistant epilepsy . Developments made in surgical techniques (cortical resections) have significantly increased the effectiveness and safety of these techniques; as such techniques have been demonstrated to improve seizure control/freedom outcomes and enhanced quality of life in patients . Neuro imaging developments with the introduction of positron emission tomography (PET), magnetic resonance imaging (MRI), functional MRI, single-photon emission computed tomography (SPECT), and magneto encephalography, electroencephalography and neuronavigation have facilitated the presurgical evaluation of patients, thus providing the lesion-directed surgeries more possible , also reducing the number and severity of complications . Complications of epilepsy surgery including failure to stop seizures and neuropsychological, psychosocial, or psychiatric impairment are still difficult to define, and there is no universal consensus in this regard .

This technique characterized by :

• Once the epilepsy focus is located by using interpretation and collection of data from functional MRI, EEG long term video and clinical findings, the specific surgery involved in treatment is decided on. The type of surgery depends on the location of the seizure focal point. Surgeries for epilepsy treatment include, but are not limited to, the following types: temporal lobe resection, ground temporal and extra temporal resection, parietal resection, occipital resection, frontal resection, extra temporal resection. ;
