What is a dural fistula in the brain?
Dural arteriovenous fistulas (dAVFs) are abnormal connections between an artery and a vein in the tough covering over the brain or spinal cord (dura mater). In this rare condition, abnormal passageways between arteries and veins (arteriovenous fistulas) may occur in the brain, spinal cord or other areas of your body.
What are the symptoms of a dural arteriovenous fistula?
dAVF symptoms may include:
- Ringing or humming in the ears (pulsatile tinnitus)
- Headaches.
- Visual troubles — bulging or swollen eyes, red eye, vision changes, double vision.
- Stroke-like symptoms or seizures.
How serious is a brain fistula?
They rarely cause serious problems with brain development. Dural arteriovenous fistulas occur within the dura, which covers the brain. Sometimes we see symptoms at birth while other times, the condition does not become apparent until later in childhood. A large dural AVF can cause cardiac failure at birth.
How do they fix a brain fistula?
Treatment Options
- Microsurgery is the most appropriate treatment for a dural, brain, or spinal AVF, either alone or in combination with endovascular embolization.
- Stereotactic radiosurgery is appropriate if an AVF is located too close to important brain structures for us to safely perform embolization or microsurgery.
Can a person live with a fistula?
Although fistulas are associated with IBD, they can occur several years before the condition is diagnosed. While rarely life-threatening, fistulas can decrease people’s quality of life and often need combined medical and surgical treatment.
Does fistula cause death?
The overall mortality of fistulas has decreased owing to better fluid and electrolyte replacement and the proper use of parenteral nutrition. However, patients continue to die from fistulas, and the cause of death is nearly always infection.

Some of the common symptoms include: Headaches Headaches are among the most common symptoms with all types of DAVFs. Ringing in Ears An unusual ringing or humming in the ears may be symptom, particularly when the DAVF is near the ear. Some patients hear a pulsating noise caused by blood flow through the fistula.
What is the survival rate of AVM surgery?
Prognosis. The prognosis of an AVM depends on several factors, beginning with whether the AVM is discovered before or after bleeding. More than 90% of those who bleed survive the event.
How urgent is fistula surgery?
Fistulas require immediate medical attention to prevent serious infections or other problems from developing. Treatment options include medications, surgery, or both. Fistulas form when inflammation causes sores, or ulcers, to form on the inside wall of the intestine or nearby organs.
Can you live a long life with AVM?
Although most people with the condition can lead relatively normal lives, they live with the risk that the tangles can burst and bleed into the brain at any time, causing a stroke. Around one in every hundred AVM patients suffers a stroke each year.
