ABSTRACT

OBJECTIVE. To describe the characteristics of the patients with epilepsy, associated to arteriovenous malformation.

PATIENTS AND METHODS We introduced 11 patients assisted in 1997, at University Cajuru Hospital, with arteriovenous malformation associated to refractory epileptic seizures.

RESULTS Six men and five women, with age between 12 and 40 years old (27 years in mean), were interned with epileptic crises, 4 generalized tonic-clonic, 3 partial simple secondarily generalized, one with complex partial and one with simple partial that the complex developed with secondary generalization. CT showed temporal lesion in 3 patients, parietal in 3 patient, ventricular in 3, parietal fose and temporoparietal en one patient, respectively. MRI was accomplished in 5 patients presenting temporal lesion in 3 and temporo-parietal in 2. It was possible to accomplish the EEG in 8 patients, all with epileptiform activity. The arteriography showed arteriovenous malformations in all the patients, 3 of the which died. Eight patients were guided for surgical treatment evidencing cavernous angioma in 6 patient and hemangioma in 2.

CONCLUSIONS We observed that cortical and not cortical arteriovenous malformation associates to epileptic seizures and in the cases in which it is possible, the surgical treatment favors the control of the seizures CategoriesEpilepsias y síndromes epilépticos
