Seizure Prophylaxis in Aneurysm Repair (SPAR)

November 6, 2024 updated by: Aditya S. Pandey, MD, University of Michigan
After a thorough review of the existing literature as well as a review of our own practice, the investigators have concluded that the decision to treat patients undergoing aneurysm repair with levetiracetam has reached true clinical equipoise. In other words, the investigators cannot favor a decision to either administer or not administer this drug in these patients based on the existing information. The utility of anti-epileptic prophlaxis in the perioperative period for patients undergoing intracranial aneurysm repair remains a common practice that is not supported by the current literature that includes retrospective analyses as well as prospective trials for similar but not identical types of patients. The investigators propose to settle this dilemma by performing a prospective randomized trial in patients undergoing aneurysm repair in order to definitively determine if the common practice of perioperative antiepileptic drug administration has any utility. The study will be extended to June 2024 to allow for a 5 year follow up of the last enrolled patient in June, 2019.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of Seizure
Time Frame: 5 years from procedure
Incidence of seizure reported as number of participants who had at least one seizure within the relevant date range. Data collected at hospital discharge, 1-2 months, 4-6 months, 6-12 months, and 5 years. Data is not cumulative. Counts reflect the number of participants who experienced a seizure since their previous check-in.
5 years from procedure

Time Frame
Duration of Seizure
Time Frame: To compare duration of seizure in each randomization group
Duration of seizure
To compare duration of seizure in each randomization group
