# Non-traumatic Spinal Subdural Hemorrhage Associated With Rivaroxaban Use

## TL;DR

This paper reports a rare case of spinal bleeding in a patient taking rivaroxaban, a blood thinner, highlighting the potential risk of this medication.

## Contribution

The paper presents a rare clinical case linking rivaroxaban use to spontaneous spinal subdural hemorrhage.

## Key findings

- A 63-year-old male on rivaroxaban developed sudden spinal subdural hemorrhage.
- Rivaroxaban is suggested to have played a major role in triggering the hemorrhage.
- Spontaneous spinal subdural hemorrhages linked to rivaroxaban are very rarely documented.

## Abstract

Spinal subdural hematoma (SSDH) is a rare medical emergency that can cause permanent neurological deficits. The disease is characterized by sudden onset back pain, sensorimotor changes, and bladder and autonomic dysfunction. This is often associated with the use of anticoagulants, blood dyscrasias, and recent spinal procedures. We present a case of a 63-year-old male maintained on rivaroxaban for nonvalvular atrial fibrillation clinically presenting with abrupt onset back pain that rapidly progressed to sensorimotor deficits and bladder dysfunction. Rivaroxaban, a selective inhibitor of factor Xa, has been approved by the Food and Drug Administration (FDA) for the reduction of stroke risk and systemic embolism in nonvalvular atrial fibrillation. We postulate that rivaroxaban played a major role in triggering the spinal hemorrhage. This case highlights the very limited documented cases of spontaneous subdural spinal hemorrhages associated with rivaroxaban use.
