A Rare Case Presentation of Apixaban-induced Nontraumatic Spinal Subdural Hematoma

A spinal subdural hematoma is a rare clinical entity and an uncommon urgent complication that can be associated with the use of vitamin K and less commonly nonvitamin K oral anticoagulants. It is considered a neurological emergency requiring prompt diagnosis and surgical intervention in the majority of the cases. Herein, we present an 84-year-old male patient with a history of nonvalvular atrial fibrillation on apixaban who presented with complaints of bilateral lower extremity weakness, severe back pain, and urinary retention. His lumbar and thoracic spine images showed a diffuse spinal subdural hematoma. Urgent neurosurgical intervention was performed with minimal improvement in his symptoms postoperatively. We report a case of spontaneous spinal subdural hematoma related to apixaban use with relevant literature review.
