[On epilepsy prevention after intracranial aneurysm surgery].

The authors evaluate in the presented prospective study the incidence of late epilepsy after aneurysm surgery. 121 consecutive patients were operated on for ruptured aneurysm and were discharged home without any prophylactic anticonvulsant treatment and were followed-up for 12 months. The diagnosis of late epilepsy was made, if two or more seizures occurred during that time. Epilepsy occurred in 8 patients, so the incidence was 7%. Additionally in 3 patients a single seizure was observed during follow-up time but any anticonvulsant treatment was installed and the seizures did not recur for up to 24 months. The analysis of epileptic patients showed that in most of them the aneurysm was located on MCA and SAH was complicated by intracerebral haematoma or symptomatic vasospasm. On the basis of own experience and review of the literature the authors discuss the necessity of anticonvulsant prophylaxis after aneurysm surgery.
