    Abstract

    Background: Patients receiving oral anticoagulation who experience a traumatic intracranial hemorrhage (ICH) should receive anticoagulation reversal. Four factor prothrombin complex concentrate (4FPCC) is indicated for reversal of warfarin, and is frequently used for reversal of direct-acting oral anticoagulants (DOACs). The purpose of this study is to compare the safety and efficacy of 4FPCC reversal for traumatic ICH in DOAC- and warfarin-anticoagulated patients. Methods: This was a single-center, retrospective review of adult patients with traumatic ICH who received 4FPCC for reversal of anticoagulation between April 2013 and August 2018. The ICH volume on the pre- and post-reversal head CT scans was measured. The primary endpoint was the incidence of expansion of ICH volume of blood using pre-and post-4FPCC imaging. Results: A total of 102 patients meeting inclusion criteria were identified with 75 patients in the warfarin group and 27 patients in the DOAC group. There were no significant differences in baseline characteristics between the groups except DOAC patients had larger ICH volumes at baseline as compared to warfarin patients (23.4 mm3 vs 3.7 mm3, p = 0.0001). There was neither a statistical difference in change in ICH volume pre-and post-4FPCC administration, nor in the rate of >20% ICH expansion between the warfarin and DOAC groups. There was no difference in the rate of adverse events compared between groups. Conclusion: There was no difference in the either the change in ICH volume or the rate of >20% ICH expansion in patients receiving 4FPCC for reversal DOAC versus warfarin anticoagulation. Rates of complications were low in both groups.
