Surgery of arteriovenous malformations (AVM) and of cavernous angiomas (cavernoma) in the majority of cases is indicated subsequently to episodes of bleeding. With the development of techniques for diagnosis and surgery for epilepsy of difficult control, indication for surgery of these vascular lesions has become greater. We present nine patients with cerebral vascular lesions and very frequent crises in spite of adequate clinical treatment. Ages ranged from 12 to 42 years with an average of 25 years; there was a prevalence of the male sex (2:1). Surgery consisted of exeresis of the lesion in all cases and in four there was also resection of the perilesional irritative area shown by electrocorticography. The pathologic study of lesions showed five cases of cavernoma, three cases of AVM, and one case of venous angioma. As to localization, we observed three lesions in the temporal lobe, four in the frontal, and two in the parietal region. Outpatient follow-up showed a reduction in crises in all of the patients, and seven evolved seizure free following surgery.
