Dural arteriovenous fistula

Dural arteriovenous fistulas (DAVFs) are pathologic vascular connections that shunt dural arterial flow directly to dural venous drainage.

DAVFs comprise 10–15% of all intracranial AVMs 1). 61–66% occur in females, and patients are usually in their 40 s or 50 s. They occur rarely in children, and when they do they tend to be complex, bilateral dural sinus malformations 2)

Dural arteriovenous fistulas can occur at any dural sinus but are found most frequently at the cavernous or transverse sinus.

Intracranial dural arteriovenous fistula.
