tPA Lawsuits
ACEP/AAN Policy 2013Level A recommendations. In order to improve functional outcomes, IV tPA
should be offered to acute ischemic stroke patients who meet National Institute of Neurological Disorders and Stroke (NINDS) inclusion/exclusion criteria and can
be treated within 3 hours after symptom onset.*
Level B recommendations. In order to improve functional outcomes, IV tPA should be considered in acute ischemic stroke patients who meet European
Cooperative Acute Stroke Study (ECASS) III inclusion/exclusion criteria and can be treated between 3 to 4.5 hours after symptom onset.*
* The effectiveness of tPA has been less well established in institutions without the systems in place to safely administer the medication.
Note: Within any time window, once the decision is made to administer IV tPA, the patient should be treated as rapidly as possible. As of this writing, tPA for acute ischemic stroke in the 3- to 4.5-hour
window is not FDA approved.
