SOP: thrombolysis in ischemic stroke under oral anticoagulation therapy.

Abstract

INTRODUCTION:

Based on demographical trends and the expected worldwide increase in the number of individuals with atrial fibrillation, the rate of patients who are on oral anticoagulation therapy for secondary prevention of stroke rises continuously. Despite correct drug intake and good adherence to the respective medication, recurrent ischemic stroke still occurs in ~ 3% of patients. The question how to deal with such patients with regard to intravenous thrombolysis with rt-PA within the 4.5 h time window is of great relevance for daily clinical routine. However, international guidelines can be considered heterogenous or do even lack recommendations on this topic especially in light of available reversal agents. Therefore, we provide this SOP.

COMMENTS:

Beyond the identification of acute stroke patients on oral anticoagulation therapy, the type of medication, time since last intake, renal function and laboratory exams as well as the availability of reversal agents have to be considered before rt-PA application and potential endovascular therapy. Treatment on a Stroke Unit or Neuro-ICU is certainly recommended in any of those patients.

CONCLUSIONS:

This standardized operating procedure was designed to guide stroke physicians through questions on eligibility for rt-PA treatment in patients with acute ischemic stroke who are on approved oral anticoagulation therapy thereby increasing the number of patients benefitting from thrombolysis and minimizing door-to-needle times.
