What is Arteriovenous Fistula?

An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein. It can occur anywhere in the body, including the brain and spinal cord. In the case of brain arteriovenous fistulas (bAVFs), abnormal connections form between arteries and veins in the brain, bypassing the normal capillary network. This can disrupt blood flow, increase the risk of bleeding, and cause neurological symptoms such as headaches, seizures, or neurological deficits. Arteriovenous fistulas can be congenital (present at birth) or acquired (develop later in life).
