Normal and abnormal blood vessels. In a brain AVM, blood passes directly from arteries to veins via a tangle of abnormal blood vessels. A brain arteriovenous malformation (AVM) is a tangle of abnormal blood vessels connecting arteries and veins in the brain. The arteries are responsible for taking oxygen-rich blood from the heart to the brain. Veins carry the oxygen-depleted blood back to the lungs and heart.
In an arteriovenous malformation (AVM), blood passes quickly from the artery to vein, disrupting the normal blood flow and depriving the surrounding tissues of oxygen. Spinal arteriovenous malformation (AVM) is a rare, abnormal tangle of blood vessels on, in or near the spinal cord. Without treatment, spinal AVM can permanently damage your spinal cord. Oxygen-rich blood normally enters your spinal cord through arteries, which branch into smaller blood vessels (capillaries).
