Arteriovenous malformations (AVM) of the brain and spinal cord are tangles of abnormal blood vessels. They can form wherever arteries and veins exist. The ones that form in the brain or spinal cord have the most serious symptoms.
Arteries in arteriovenous malformations don’t flow properly. They dump blood directly into veins through a channel called a fistula, an abnormal tube-like opening. The blood flows through this fistula too quickly.
