Spinal dural arteriovenous fistula: a treatable cause of myelopathy.

Spinal vascular malformations (SVM) are rare diseases in comparison to vascular malforma‐ tions of the brain. Spinal dural arteriovenous fistulas (SDAVFs), also known as Type I spinal arteriovenous malformations, account for 70% of spinal vascular malformations, and are the most common vascular malformations of the spinal cord and its surrounding dura mater; however, they remain relatively under-diagnosed. The majority of SDAVFs occur spontane‐ ously, but a post-traumatic aetiology cannot be excluded in a significant proportion of them (Aghakhani N et al., 2008).
