What is an Arteriovenous Malformation (AVM)?
(Symptoms, Causes & Treatment)
Arteriovenous malformations (AVMs) are rare defects in the body’s vascular system. AVMs can happen anywhere, but they are most common in the brain or spinal cord. Most people with brain or spinal cord AVMs have few, if any, major symptoms. In some people they can cause seizures or headaches. The greatest danger is hemorrhage. The exact cause of arteriovenous malformations is unknown. According to the U.S. Library of Medicine, these malformations seem to develop during pregnancy or soon after birth. Treatment for AVMs can include surgery or focused radiation therapy.
The American Stroke Association estimates that Brain AVMs occur in less than 1 percent of the general population. It’s estimated that about one in 200–500 people may have an AVM. AVMs are more common in males than in females.
