Case ReportsIntravenous thrombolysis in an elderly patient with acute ischemic stroke masking aortic dissection.
Before thrombolytic treatment for acute ischemic stroke is undertaken, conditions associated with increased risk of hemorrhagic complications, such as an acute aortic dissection (AAD), should be excluded. We report an 80-year-old woman with acute ischemic stroke as the sole clinical manifestation of AAD who was treated with intravenous (IV) tissue plasminogen activator (tPA). She had no history of hypertension or any signs or symptoms suggestive of AAD. ⋯ Infusion of tPA was stopped, and subsequent computed tomography angiography confirmed Stanford type A aortic dissection. In this case, prompt neurosonologic evaluation helped us make an appropriate diagnosis and avoid complications related to treatment. Neurosonologic evaluation should be considered as soon as possible in all patients with acute ischemic stroke, especially when thrombolytic treatment is being considered.

Factors associated with misdiagnosis of acute stroke in young adults.
Misdiagnosis or delayed diagnosis of acute ischemic stroke can result in neurologic worsening or a missed opportunity for thrombolysis. Because stroke in young adults is less common than stroke in the elderly, we sought to determine clinical characteristics associated with misdiagnosis of stroke in young adults. Patients from the prospectively maintained Young Stroke Registry in our comprehensive stroke center were reviewed. ⋯ Patients presenting with vertebrobasilar territory ischemia have a greater rate of misdiagnosis. Our study demonstrates the increasing need for "young stroke awareness" among emergency department personnel. Initial misdiagnosis can potentially lead to a lost opportunity for thrombolysis in otherwise good candidates.
