Arteriovenous Malformations (AVM)

An Arteriovenous Malformation (AVM) is a tangled ball of blood vessels with abnormal connections between arteries and veins. AVMs are rare — affecting less than 0.1 percent of Americans.

An AVM can occur anywhere in the body, but are particularly dangerous in the brain. They can lead to stroke-like symptoms and, in rare cases, the risk of a fatal stroke.

AVMs are found in people of both sexes and all racial and ethnic backgrounds. AVMs form as a fetus develops during pregnancy, but there is no known cause. They are not associated with any activity or medication during pregnancy or any complications of birth.

Our renowned specialists and experienced surgeons at the Swedish Neuroscience Institute are experts in the diagnosis and treatment of brain AVMs.
