Characterized by headaches and seizures, an arteriovenous malformation (AVM) of the brain is a derivative of arteriovenous malformation, a disorder of the body’s circulatory system. An AVM of the brain, also known as a cerebral AVM, is a malformed group of blood vessels composed of an intricate tangle of arteries and veins. Though localized, cerebral AVMs can lead to severe neurological problems. Research in the field of arteriovenous malformation is growing particularly with noninvasive treatment options.
