We studied eleven patients with intrathecal extramedullary arteriovenous fistulas identified by selective angiography and myelography. The fistulas were located on the surface of the cord, fed by medullary arteries. Angiography distinguished three separate types that gave identical clinical disorders. Therapeutic results of surgery and embolization allowed specific indications to be defined for treatment of each type of fistula.
