Thrombolytic Therapy in Severe Cardioembolic Stroke After Reversal of Dabigatran with Idarucizumab: Case Report and Literature Review

Whether idarucizumab, an antidote of dabigatran, can be used effectively and safely before thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) in patients with stroke undergoing treatment with dabigatran remains unknown. We herein describe a 57-year-old man who developed severe cardioembolic stroke with a National Institutes of Health Stroke Scale score of 22 in the left middle cerebral artery territory while undergoing treatment with dabigatran for nonvalvular atrial fibrillation and who was treated with rt-PA after the reversal of dabigatran with idarucizumab. The thrombolytic therapy following the use of idarucizumab significantly improved the patient's neurological symptoms without hemorrhagic complications, although acute arterial occlusion of the right lower limb was found during the clinical course.
