A single-center, long-term study of spinal dural arteriovenous fistulas with multidisciplinary treatment.

Spinal dural arteriovenous fistulas (SDAVF) are the most frequently occurring vascular malformations of the spinal cord but their optimal treatment remains contentious. We retrospectively analyzed 19 consecutive patients treated between 1996 and 2007. Endovascular embolization was considered the first treatment option for nine patients.
