Abstract

Purpose of Review: This article provides an update on the state of the art of the emergency treatment of acute ischemic stroke with particular emphasis on the alternatives for reperfusion therapy.

Recent Findings: The results of several randomized controlled trials consistently and conclusively demonstrating that previously functional patients with disabling strokes from a proximal intracranial artery occlusion benefit from prompt recanalization with mechanical thrombectomy using a retrievable stent have changed the landscape of acute stroke therapy. Mechanical thrombectomy within 6 hours of symptom onset should now be considered the preferred treatment for these patients along with IV thrombolysis with recombinant tissue plasminogen activator (rtPA) within the first 4.5 hours for all patients who do not have contraindications for systemic thrombolysis. Patients who are ineligible for IV rtPA can also benefit from mechanical thrombectomy. Collateral status and time to reperfusion are the main determinants of outcome.

Summary: Timely successful reperfusion is the most effective treatment for patients with acute ischemic stroke. Systems of care should be optimized to maximize the number of patients with acute ischemic stroke able to receive reperfusion therapy.
