[Surgery for epilepsy: evaluation and indication]
1Servicio de Neurología, Hospital Clínic i Provincial, Barcelona.
Abstract:
Surgery for epilepsy is effective for the controlling of seizures in patients with pharmacoresistant forms. To screen candidates for surgery, diagnosis must be certain sure and the form must be drug resistant. Seizures must interfere with quality of life and the patient must be medically and psychologically stable. Selecting patients for surgery demands meticulous evaluation, including prolonged video-EEG to record seizures, magnetic resonance and, often, additional function imaging tests and neuropsychological examination. The most frequently performed surgery and the type with the best results is temporal lobectomy in patients with complex partial seizures arising in the mesial temporal lobe. Other techniques, such as hemispherectomy, callostomy or reduced cortical or extratemporal lobar resection, can yield improved or total control over seizures in certain patients.
Insights
Epilepsy surgery effectively controls seizures in drug-resistant patients. Meticulous evaluation ensures surgical candidates are medically stable and have disabling seizures, improving quality of life.
Area of Science:
- Neurology
- Neurosurgery
Background:
- Epilepsy surgery is a viable treatment for pharmacoresistant epilepsy.
- Careful patient selection is crucial for successful surgical outcomes.
Purpose of the Study:
- To outline the criteria and methods for selecting epilepsy surgery candidates.
- To highlight the effectiveness of various surgical interventions.
Main Methods:
- Prolonged video-electroencephalography (EEG) monitoring.
- Magnetic Resonance Imaging (MRI) and functional imaging.
- Neuropsychological examinations.
Main Results:
- Temporal lobectomy is the most common and effective surgery for mesial temporal lobe epilepsy.
- Alternative procedures like hemispherectomy and callosotomy offer seizure control in specific patient groups.
Conclusions:
- Meticulous pre-surgical evaluation is essential for identifying suitable candidates.
- Epilepsy surgery, particularly temporal lobectomy, significantly improves seizure control and quality of life for select patients.
