Corpus callosum section for patients with intractable epilepsy

Microsurgical techniques of callosotomy were effective in relieving medically intractable epilepsy in 14 of 16 patients. Intra-arterial digital angiography has been used preoperatively to assess drainage of the veins of the frontal lobe. MRI is useful in verifying the postoperative extent of corpus callosum section. Patients with bilateral frontal lesions and unilateral destructive lesions responded to callosotomy. None of the patients had an increase in seizures after the procedure.
