title: Metachronous double spinal dural arteriovenous fistulas. Case report and review of the literature.
abstract: Spinal dural arteriovenous fistulas (DAVFs), the most common of spinal vascular malformations, are AVFs in the dura mater of the nerve root and/or adjacent spinal dura. These fistulas are most often solitary and are fed by a single radicular artery that primarily supplies the dura mater. Multiple spinal DAVFs are rarely reported in the literature. Those that have been documented have been synchronous in their presentation in that they were found during the same examination or were present at the initial examination but missed and only recognized at the second examination. The authors report the case of a patient with two spinal DAVFs occurring at different spinal levels at different points in time (metachronous).
