Surgical and endovascular treatment of spinal dural arteriovenous fistulas: long-term disability assessment and prognostic factors

Abstract

Spinal DAVF treatment significantly improved patients' mean gait disability score by almost one grade at last follow up. The mean micturition disability score was not significantly improved, unless treatment was performed within 13 months of symptom onset. Longer and more uniform follow-up study is needed to determine if improved and stabilized clinical outcomes are sustained.
