Multiple subpial transection for treatment of intractable epilepsy
Chinese Medical Journal
|July 1, 1995
Summary
Multiple subpial transection (MST) effectively treated intractable epilepsy in 50 patients with lesions near critical brain areas. This surgical technique achieved a 96% success rate without causing functional deficits.
Area of Science:
- Neurosurgery
- Epileptology
- Clinical Neurology
Background:
- Intractable epilepsy often involves epileptogenic lesions in or near critical functional brain areas.
- Standard excisional therapies may risk neurological deficits when targeting these sensitive regions.
Purpose of the Study:
- To evaluate the efficacy and safety of multiple subpial transection (MST) for treating intractable epilepsy with lesions in functional areas.
- To explore MST as an alternative to excisional surgery in specific epilepsy cases.
Main Methods:
- A cohort of 50 patients with intractable epilepsy and lesions in functional areas underwent multiple subpial transection (MST).
- Patients were monitored post-surgery for seizure control and functional outcomes over a 6 to 40-month follow-up period.
Main Results:
- Complete seizure control was achieved in 32 patients (64%).
- Significant seizure reduction ( >50%) occurred in 13 patients (26%).
- The overall effective rate was 96%, with no observed functional deficits in any patient.
Conclusions:
- Multiple subpial transection (MST) is a highly effective and safe surgical option for intractable epilepsy involving functional brain areas.
- MST offers a promising alternative to standard excisional therapies, preserving neurological function while controlling seizures.
