BACKGROUND: Thrombolytic treatment with intravenous tissue plasminogen activator (i.v. tPA) is the only FDA-approved therapy for acute ischemic stroke. There are risks associated with thrombolytics, including intracranial and extracranial hemorrhage and hypersensitivity reactions. Established treatment for post-tPA hemorrhage includes administration of blood products including cryoprecipitate, fresh frozen plasma, and platelets which have poorly established efficacy. Tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA) have been studied as hemostatic therapies in post-operative hemorrhage, menorrhagia, intracranial hemorrhage (ICH), subarachnoid hemorrhage, and trauma patients. There is no reported literature on the use of TXA to reverse thrombolytic therapy with tPA.
METHODS: This is a case report of a Jehovah's Witness patient who was unwilling to receive blood products after developing symptomatic ICH following i.v. tPA. He consequently received TXA for reversal of thrombolytic therapy.
RESULTS: The patient received a total of 1.675 g of i.v. TXA within 3 h of finishing the iv tPA. Repeat brain imaging with computed tomography and magnetic resonance imaging revealed no further expansion of hemorrhages.
CONCLUSION: TXA is an inexpensive medication which competitively inhibits the activation of plasminogen and can be given to reverse thrombolysis in the setting of hemorrhage after i.v. thrombolytic therapy.
