Arteriovenous Malformation (AVM)

Arteriovenous Malformation (AVM)

Treatment for an arteriovenous malformation will depend on a number of things. Most specifically the size and the location of the abnormal blood vessels. Although medications may be used to treat such symptoms as headaches or seizures, the AVM may need to be removed in order to prevent future rupture.

Surgical resection: this treatment is relatively safe and effective. During a surgical resection, a small portion of the skull is removed to gain access to the AVM. The AVM is then sealed off with special clips and it is removed from the surrounding brain tissue. The skull bone is then reattached. This type of surgery is usually performed when the AVM can be removed with acceptable risk.

Endovascular embolization: similar to the treatment for aneurysms, this is done by threading a thin tube through a vein in the groin and up to the brain arteries that is feeding blood to the AVM. A substance is injected to block the vessel and reduce blood flow to the AVM.

Gamma Knife radiosurgery: this treatment is not actually a surgery at all and does not require open access to the brain and does not cause any blood loss. This treatment delivers focused dosages of radiation to destroy the AVM. SCCNS is proud to be one of the only providers to offer Gamma Knife treatment at the Regional Gamma Knife Center in Upland, CA.
