Summary
Hemispherotomy offers a safer surgical alternative for intractable epilepsy, achieving good outcomes in most patients. This technique provides a less invasive option compared to traditional hemispherectomy.
Area of Science:
- Neurosurgery
- Epileptology
Background:
- Hemispherectomy is a treatment for intractable epilepsy due to severe unilateral brain damage.
- Anatomic hemispherectomy has severe complications, leading to less resective hemispherotomy techniques.
- Hemispherotomy variations offer fewer complications but less favorable outcomes than anatomic hemispherectomy.
Purpose of the Study:
- To outline the indications and surgical technique of hemispherotomy.
- To report clinical experience and outcomes of hemispherotomy.
Main Methods:
- Surgical procedure: hemispherotomy.
- Patient cohort: 9 individuals with medically intractable epilepsy.
- Follow-up duration: 5 years.
Main Results:
- 66.6% (6/9) achieved Engel class I outcome.
- 22.2% (2/9) achieved Engel class II outcome.
- 11.1% (1/9) achieved Engel class III outcome.
- No mortality and significantly reduced operative blood loss were observed.
Conclusions:
- Hemispherotomy is a safe and technically simple surgical alternative.
- It is less efficacious than anatomic hemispherectomy but suitable for intractable seizures.
- The procedure demonstrates favorable outcomes with minimal complications.
