Intracranial Hemorrhage following Lumbar Puncture in a Patient on Apixaban

Abstract

Currently, clinical practice recommendations regarding patients in need of emergent lumbar puncture who are taking direct oral anticoagulants (DOACs) are based upon expert opinion, as evidence-based guidelines are unavailable. We present the case of an 80-year-old Caucasian lady who underwent diagnostic lumbar puncture for presumed meningitis while on therapeutic apixaban for nonvalvular atrial fibrillation. She was subsequently found to have bilateral subdural hematomas. This case report reviews both the current criteria for computerized tomography brain imaging prior to lumbar puncture as well as the bleeding risks of lumbar puncture while on a DOAC.
