Objective: To investigate the curative effect of electrocorticography (ECoG) monitoring in the microsurgical treatment of cavernous angiomas.
Methods: Clinical data of 71 patients with epileptogenic cavernous angiomas,who had been performed ECoG monitoring during the operation,were analyzed retrospectively.
Results: The foci of cavernous angiomas and epilepsy of the 71 patients were resected during the operation. In the 58 patients who were followed up,42 had not epileptic seizure,and 16 still had epileptic seizure,while the frequencies of 13 patients reduced to below 10%,and 3 patients over 10%.
Conclusion: The drug treatment of epileptogenic cavernous angiomas can not control epileptic seizure,and the patients should receive the microsurgical treatment early. Electrocorticography monitoring can direct the surgical procedure,and control the postoperative epileptic seizure.
