Vascular Aphasia Outcome after Intravenous Recombinant Tissue Plasminogen Activator Thrombolysis for Ischemic Stroke

Abstract

Introduction: No data about the specific outcome of aphasia after thrombolysis are available. Our aim was to describe the severity and type of aphasia after stroke thrombolysis. Methods: This retrospective cohort study included consecutive aphasic patients hospitalized in the Stroke Unit of Dijon (University Hospital, France) between 2004 and 2009 for a first-ever ischemic stroke of the left middle cerebral artery. Aphasic syndromes and their severity (French version of the Boston Diagnostic Aphasia Examination) were evaluated during the first week and 3 months after stroke. Results: In multivariate analyses, the severity of aphasia in the 37 thrombolysed patients was milder than in the 38 nonthrombolysed patients during the first week (adjusted OR = 10.13, 95% CI: 2.43-42.28, p = 0.002) and at 3 months (adjusted OR = 8.44, 95% CI: 2.76-25.80, p = 0.001). The frequency of mild aphasia (conduction or atypical) was not significantly higher in thrombolysed patients during the first week after stroke (adjusted OR = 5.80, 95% CI: 0.82-41.16, p = 0.079). Conclusion: The severity of aphasia during the first week and 3 months after stroke is milder in thrombolysed than in nonthrombolysed patients, perhaps because of a greater frequency of conduction and mild atypical aphasia.
