Özet

Objective To identify characteristics, predictors, and outcomes of acute symptomatic seizures (ASS) in cerebral venous thrombosis (CVT), we investigated 1,281 consecutive adult patients with CVT included from 12 hospitals within the International CVT Consortium. Methods We defined ASS as any seizure between symptom onset and 7 days after diagnosis of CVT. We stratified ASS into prediagnosis and solely postdiagnosis ASS. Status epilepticus (SE) was also analyzed separately. We analyzed predictors for ASS and the association between ASS and clinical outcome (modified Rankin Scale) with multivariable logistic regression. Results Of 1,281 eligible patients, 441 (34%) had ASS. Baseline predictors for ASS were intracerebral hemorrhage (ICH; adjusted odds ratio [aOR] 4.1, 95% confidence interval [CI] 3.0-5.5), cerebral edema/infarction without ICH (aOR 2.8, 95% CI 2.0-4.0), cortical vein thrombosis (aOR 2.1, 95% CI 1.5-2.9), superior sagittal sinus thrombosis (aOR 2.0, 95% CI 1.5-2.6), focal neurologic deficit (aOR 1.9, 95% CI 1.4-2.6), sulcal subarachnoid hemorrhage (aOR 1.6, 95% CI 1.1-2.5), and female-specific risk factors (aOR 1.5, 95% CI 1.1-2.1). Ninety-three (7%) patients had solely postdiagnosis ASS, best predicted by cortical vein thrombosis (positive/negative predictive value 22%/92%). Eighty (6%) patients had SE, independently predicted by ICH, focal neurologic deficits, and cerebral edema/infarction. Neither ASS nor SE was independently associated with outcome. Conclusion ASS occurred in one-third of patients with CVT and was associated with brain parenchymal lesions and thrombosis of the superficial system. In the absence of prediagnosis ASS, no subgroup was identified with sufficient risk of postdiagnosis ASS to justify prophylactic antiepileptic drug treatment. We found no association between ASS and outcome.
