What is it?

Arteriovenous malformations are made from incorrectly formed arteries and veins that connect and create a tangled web that “steals” the body’s blood flow. This malformations are considered “high-flow” indicating an increased bleeding risk and can be formed anywhere on the body. These malformations are usually present at birth but can be formed shortly after birth. While arteriovenous malformations can be present at birth, they may go undiagnosed until adolescence or later in life.
