RESUMO
Since the introduction of recombinant tissue plasminogen activator and thrombolysis, acute ischemic stroke has become a treatable disorder if the patient presents within the 4.5-hour time window. Typically, sporadic stroke is caused by atherosclerotic disease involving large or small cerebral arteries or secondary to a cardioembolic source often associated with atrial fibrillation. In the over-65-year age group, more rare causes of stroke, such as antiphospholipid syndromes, are unusual; such stroke etiologies are mostly seen in a younger age group (<55 years). Here we describe acute ischemic stroke in three patients >65 years with hepatitis C-associated antiphospholipid antibodies. We suggest that screening for antiphospholipid disorders in the older patient might be warranted, with potential implications for therapeutic management and secondary stroke prevention.
