Dural Arteriovenous Fistulas (DAVF)


The Valley Hospital neurointerventional experts have the training, expertise and technology to treat Dural arteriovenous fistulas (DAVF). This condition is treated with a procedure known as Onyx embolization. Other embolization techniques exist too.

Dural arteriovenous fistulas (DAVF) occur in the strong membrane that protects the brain. When an abnormal connection develops between arteries and channels within that membrane, it is called dural arteriovenous fistula (DAVF). Also known as dural arteriovenous malformation or dural fistula, DAVF's can be formed due to clotting and blockage of the dural sinuses, head injury, and open surgery. DAVFs can lead to stroke, seizure, and brain hemorrhaging if not diagnosed and treated.

Symptoms of DAVFs can vary and depend on the location. Symptoms can include:

  • Headache your head.
  • Decreased vision, swelling and redness of the eye.
  • Pulsating noise (tinnitus) due to the fast blood flow going through the fistulas.
  • Stroke-type symptoms and seizures.
