The efficacy of antiepileptic drug (AED) prophylaxis in patients undergoing aneurysm repair has been questioned, yet these drugs are routinely used in many institutions. To better define the relationship of AED prophylaxis to postoperative seizures, we undertook a review of 259 patients undergoing treatment for intracranial aneurysms. Incidence of late seizures was assessed by telephone interview in 132 patients (mean follow-up, 58.7months). There were seven early seizures, all in patients who received AED prophylaxis (higher versus [vs.] no prophylaxis, p=0.019). There were 12 late seizures (nine with prophylaxis vs. three without prophylaxis, p=0.53). The timing of AED prophylaxis had no…
