BackgroundNon-vitamin K antagonist oral anticoagulants (NOACs), such as dabigatran, are widely used to prevent ischemic stroke in patients with nonvalvular atrial fibrillation. Nonetheless, stroke occurs in 1-2% of patients, and the use of NOACs may increase the bleeding risk for patients who are receiving acute treatment of intravenous thrombolysis (IVT) or endovascular thrombectomy (EVT). Idarucizumab, a monoclonal antibody developed to bind dabigatran, has been proven safe and effective for patients with uncontrolled bleeding or for patients planning to receive emergent procedures. It is now accepted that patients taking dabigatran with recurrent stroke may benefit from IVT after idarucizumab. However, there are limited data regarding idarucizumab use in patients planning to have EVT.Case ReportWe present the case of a male patient taking dabigatran who had a stroke and who was treated with idarucizumab followed by combined IVT and EVT. The patient had immediate recanalization of the occluded vessel and near total recovery of function after 3 months. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Our case report supports the evidence that patients presenting with acute ischemic stroke (AIS) despite being under dabigatran therapy should be evaluated for reversal by idarucizumab which can contribute to the eligibility for IVT as well as EVT. It has also been proved to provide better outcomes for patients with AIS. The availabilities of specific reversal agents for NOACs will probably alter the current management of patients with AIS.Copyright © 2019 Elsevier Inc. All rights reserved.
