Meta Analysis Comparative Study
In acute ischemic stroke, are asymptomatic intracranial hemorrhages clinically innocuous?
In patients with acute ischemic stroke, intracranial hemorrhages are categorized as symptomatic or asymptomatic based on the presence or absence of a clinically detectable neurological deterioration. Asymptomatic intracranial hemorrhages are believed by many to be clinically innocuous. We examined whether the occurrence of an asymptomatic intracranial hemorrhage affects functional outcome in patients with acute ischemic stroke (AIS) treated or not treated with recombinant tissue plasminogen activator (rt-PA). ⋯ We could not confirm or exclude a clinically significant effect for asymptomatic intracranial hemorrhages based either on our analysis or on any previously published trial. Analysis of substantially larger databases are needed to assess the import of this common clinical event.
