Arteriovenous Malformations

What are arteriovenous malformations (AVMs)?

Arteriovenous malformations (AVMs) are defects in your vascular system. Your vascular system is your body's network of blood vessels. It includes your:

  • Arteries, which carry oxygen-rich blood from your heart to your tissues and organs.
  • Veins, which carry the blood and waste products back to your heart.
  • Capillaries, which are tiny blood vessels that connect your small arteries to your small veins.

An AVM is an abnormal tangle of arteries and veins. They are connected to each other, with no capillaries between them. Without the capillaries, the blood flow from the arteries goes directly into the veins at a faster rate than normal. Because of this, the nearby tissue does not get all the oxygen it would normally get. This lack of oxygen can lead to tissue damage and the death of nerve cells and other cells. The fast rate of blood flow can also increase the blood pressure inside the arteries and veins. This can weaken the arteries and veins. A weakened artery or blood vessel could burst or leak blood.
