[Multiple subpial transection in surgical treatment of intractable epilepsy]
1Neurosurgical Center of Navy General Hospital, Chinese People's Liberation Army, Beijing 100037.
Objective:
To increase the effect of epilepsy surgery, we use multiple subpial transection (MST) clinically on the basis of experimental study.
Method:
We analyzed the seizure type and course of 116 intractable epilepsy patients treated with MST and surgical technique were modified.
Result:
100 patients were followed up for 1 to 5 years. Complete control of seizure was obtained in 62 patients (62%), significant reduction (over 75%) in 20 (20%), reduction (over 50%) in 12 (12%), and no change in 6 (6%). The total effective rate was 94%, and the significant effective rate was 82%. No functional defect was found in any patients.
Conclusion:
MST is a effective in surgical treatment of intractable epilepsy and can replace conventional methods. Combined bilateral frontal lobe MST and anterior callosotomy is a good way to treat intractable generalized epilepsy.
