Dural Arteriovenous Fistulas

These are abnormal connections between arteries and veins in the covering of the brain, known as the dura. This condition is usually acquired and can occur after trauma, infection or clotting off of the veins. Symptoms include headaches, bleeding into the brain and abnormal noises in the head due to increased blood flow.

The primary neuro-interventional treatment is embolization, during which a glue-like material is injected via a catheter into the blood vessels to block them off.
