Modified hemispherectomy for epilepsy: early results in 10 cases

Area of Science:

• Neurosurgery
• Pediatric Neurology
• Epileptology

Background:

• Infantile hemiplegia is a severe neurological condition often associated with intractable epilepsy.
• Epilepsy in this context frequently leads to significant motor, cognitive, and behavioral impairments.
• Modified hemispherectomy is a surgical option explored for such complex cases.

Purpose of the Study:

• To present early outcome results of modified hemispherectomy in patients with infantile hemiplegia and intractable epilepsy.
• To evaluate the impact of the procedure on seizure control.
• To assess changes in motor, cognitive, and behavioral functioning post-surgery.

Main Methods:

• A case series of 10 patients undergoing modified hemispherectomy was analyzed.
• Pre- and postoperative assessments were conducted for seizure frequency, motor function, cognitive abilities, and behavior.
• Longitudinal follow-up data were collected to evaluate outcomes over time.

Main Results:

• No mortality was observed, with a low complication rate.
• Seven patients achieved complete seizure cessation; two experienced significant seizure reduction.
• Motor functioning remained largely unaffected.
• Behavioral problems improved following seizure control.
• Cognitive functioning, including IQ scores, did not deteriorate, with some patients showing considerable gains.

Conclusions:

• Modified hemispherectomy is a safe and effective early intervention for intractable epilepsy in infantile hemiplegia.
• The procedure leads to substantial seizure control and potential improvements in cognitive and behavioral outcomes.
• Further research is warranted to explore long-term efficacy and patient selection criteria.
