Dural Arteriovenous Fistula
What is a dural arteriovenous fistula?
A dural arteriovenous fistula is a condition where there is an abnormal connection between the arteries and veins of the membrane surrounding the brain (the dura mater), causing gradual impairment. Dural arteriovenous fistulas connect the branches of dural arteries to dural veins or a venous sinus.
Dural arteriovenous fistula symptoms can include the following:
- Cranial nerve palsies
- Focal neurological deficits
- Orbital symptoms
- Raised intracranial pressure
- Symptoms of venous hypertension
How is it diagnosed?
Digital subtraction angiography remains the best method for diagnosing dural arteriovenous fistulas.
Types of treatment
One of the first line options available for the management of dural arteriovenous fistulas is endovascular treatment.
