Background and Purpose-The aim of this study was to analyze epileptic seizures and their impact on outcome in patients with stroke treated with endovascular therapy. %26lt;br%26gt;Methods-From December 1992 to December 2010 we managed 805 patients with stroke with endovascular therapy. Epileptic seizures, bleeding complications, and 3-month outcomes were recorded prospectively. Outcomes of patients with early seizures (within 24 hours of stroke onset) and patients with late seizures (%26gt;24 hours after stroke) were compared with outcomes of seizure-free patients using uni- and multivariable statistics. %26lt;br%26gt;Results-Forty-four of 805 patients (5.5%) had seizures between stroke onset and 3-month follow-up, 26 patients early and 18 late. Outcome of patients with late seizures and seizure-free patients was similar (P=0.144 and 0.807). Patients with early seizures had higher baseline National Institutes of Health Stroke Scale (P=0.023) and were younger (P=0.021) than seizure-free patients. Their mortality rate was 50% compared with 22.3% of the seizure free-patients (P=0.003), and less patients reached a favorable outcome (modified Rankin Scale 0-2): 15.4% and 46.8%, respectively (P=0.001). Early seizures independently predicted an unfavorable outcome (P=0.014; OR, 4.749; 95% CI, 0.376-3.914) and increased mortality (P=0.001; OR, 5.861; 95% CI, 0.770-2.947) in multiregression analysis. Patients with early seizures had a 1.6-fold higher risk for unfavorable outcome and a 2.2-fold higher risk for death compared with seizure-free patients. %26lt;br%26gt;Conclusions-Seizures within 24 hours of stroke onset were associated with worse outcome in patients with stroke undergoing endovascular therapy. Our findings confirm a need for trials for prophylactic anticonvulsive treatment in patients receiving endovascular therapy for acute stroke. (Stroke. 2012;43:1584-1590.)
