Arteriovenous Malformations

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 a snarled tangle of arteries and veins. They are connected to each other, with no capillaries. That interferes with the blood circulation in an organ.
