| ABSTRACT |
|
Acute aortic dissection is a catastrophic, often life threatening event that usually presents as a sudden, severe, exquisitely painful, ripping sensation in the chest or back.
Painless dissection occurs in approximately 5% of the patients, and the diagnosis may often be delayed. It can be associated with neurologic sequelae, such as ischemic stroke, spinal cord ischemia, ischemic peripheral neuropathy, in as many as one-third of the patients. As an initial manifestation, neurologic deficit is seen in about 20% of patients. The diagnosis of ischemic stroke in patients who present within a 3-hour time window is generally made on clinical grounds before administration of thrombolytic therapy. The etiology of the stroke is not definitely determined until well after the patient has received recombinant tissae plasminogen activator. It is likely that poor outcomes will occur in ischemic stroke resulting from aortic dissection if r-tPA is administered intravenously. Therefore, it is important to clinically recog-nize this possibility. We report the case of a patient who presented with symptoms consistent with acute ischemic stroke and was given r-tPA. Further investigation demon-strated an aortic dissection as the cause of her stroke. |
