What Is a Hemispherectomy?

Cerebral hemisphere resection is a complete or subtotal excision of the cerebral hemisphere cortex on one side of the epileptogenic focus, retaining the basal ganglia and thalamus. It is suitable for epilepsy patients with infantile hemiplegia with severe seizures and behavior disorders. Before the operation, an air-encephalography or CT scan must be performed to confirm that the lesion is limited to one side of the hemisphere. The affected side has atrophy and the opposite side is normal. The effective rate of controlling epilepsy after surgery can reach 80% to 100%, and the improvement of behavior disorders is 93. %, Hemiplegia is not exacerbated, and intellectual improvement is not obvious. ^[1]
