About this Condition
A brain AVM (arteriovenous malformation) is an abnormal connection between arteries and veins bypassing capillaries. An AVM is typically congenital, meaning it dates to birth. An AVM can develop anywhere in your body but occurs most often in the brain or spine. A brain AVM, which appears as a tangle of abnormal arteries and veins, can occur in any part of your brain. The cause isn't clear.
You may not know you have a brain AVM until you experience symptoms, such as headaches or a seizure. In serious cases, the blood vessels rupture, causing bleeding in the brain (hemorrhage). Once diagnosed, a brain AVM can often be treated successfully.

A cerebral arteriovenous malformation is often difficult to treat and may require many different specialists. The goal in treating a cerebral AVM is to cut off the blood supply to the AVM. AVM resection is an open surgical procedure whereby the surgeon creates an opening in the skull to allow for full visualization of the AVM. Once the skull is opened, the surgeon identifies the margins of the AVM and then clips the arterial vessels that feed it. The surgeon will remove or destroy the veins that drain the AVM and also the nidus (the direct connection of the arteries and veins). Endovascular embolization or radiosurgery may also be used in certain cases.Read More
