Abstract WP84: Thrombolysis is Safe in the Nonagenarians With Acute Ischemic Stroke

Introduction: People aged 90 years or older are the fastest growing group in North America. This group was excluded from traditional clinical trials of intravenous tissue plasminogen activator (iv tPA) thrombolysis. IV tPA is the most beneficial emergent therapy in acute ischemic stroke (AIS). We have compassionately treated AIS patients in this age group with iv tPA in recent years. Hypothesis: Our aim is to evaluate the safety and outcome of iv tPA use in nonagenarian patients with AIS Methods: Consecutively iv tPA-treated AIS patients who were older than 90 years and were admitted at our institution from January 2004-June 2015 were included. The administration of iv tPA was within 3 hours after the stroke onset. We reviewed the clinical features of the patients at presentation, complications, and outcomes. Outcome measures at discharge included improvement of NIHSS, mRS, symptomatic intracranial hemorrhage (sICH), and discharge disposition. We also assessed the rate of complications of iv tPA.
