Percutaneous intravertebral body embolization of a traumatic spinal epidural arteriovenous fistula with secondary perimedullary venous reflux. A case report.

SUMMARY: Arteriovenous fistulas following vertebral fractures are probably very rare. We present a case with fistulous connection between arteries and veins within the fractured 12th thoracic vertebral body with retrograde venous drainage to perimedullary veins resulting in spinal venous hypertension and a cauda equina like symptomatology. Pre-treatment 3D CT enabled us to puncture the venous pouch within the vertebra and deposit glue in the vertebral fistula. The procedure led to a complete occlusion of the fistula and relief of pain and neurological symptoms.
