Every year in North America, approximately 3 million patients are evaluated for spinal injury. Of blunt trauma patients presenting to the emergency department, 3% to 4% will have a cervical spine injury, and up to 18% will suffer a thoracolumbar spine injury. Failure to identify an unstable spine injury can lead to devastating outcomes.

Spinal dural fistulas (SDAVFs) occasionally arise from the same segmental artery as the radiculomedullary branch to the anterior spinal artery. In such cases, selective fistula embolization that does not endanger the anterior spinal artery is not possible, and surgical fistula disconnection is recommended. We present an exceptional case in which rational embolization strategy of SDAVF was feasible because of separate origins from a common segmental artery pedicle of the ventral radiculomedullary artery and the dorsal radicular artery branch supplying the fistula.
