Abstract
Clinical outcome was examined in 21 patients treated for spinal dural arteriovenous fistula after 5–50 months. We compared the neurological condition (motor function, pain, sensory disturbance, vegetative dysfunction) and Barthel index before and after fistula occlusion. Neurological impairment was assessed as improved, unchanged, or deteriorated. All patients initially showed paraparesis of varying degree, and a sensory loss with a defined level in 81% before treatment. The greatest postoperative change that we measured was in motor activity (67% improved), and the most important deterioration was in male potency (28% deteriorated). We observed unchanged or absent symptoms in pain in 71% of our patients. We were thus able not only to stop but even to reverse the progression of symptoms and the degree of disability. On average, neurological symptoms stabilized within 1 year. The results of this study confirm that spinal dural arteriovenous fistula should be treated as early as possible after diagnosis.
