A Brain Arteriovenous Malformation (AVM) is a complex network of abnormal blood vessels connecting arteries and veins in the brain. The arteries are responsible for carrying oxygen-rich blood from the heart to the brain while veins return the oxygen-depleted blood back to the lungs and heart. However, a brain AVM disrupts this vital process. Arteriovenous malformations can occur anywhere in the body, but they are most commonly found in the brain or spine. Despite this, they are rare and affect less than 1 percent of the population. The cause of AVMs is uncertain as most individuals are born with them; however, they can sometimes develop later in life. They are hardly hereditary. Some individuals with AVMs experience headache or seizures. After a brain scan for another health issue or a ruptured blood vessel, AVMs are commonly discovered and cause bleeding in the brain (hemorrhage). Once diagnosed, a brain AVM can be successfully treated to prevent further complications like brain damage or stroke.
