![]() ![]() Surgery is the most common treatment for brain AVMs. Medications may be used to treat symptoms caused by the AVM, such as headaches or seizures. ![]() The most appropriate treatment for your condition depends on your age, health, and the size and location of the brain AVM. The main goal of treatment is to prevent hemorrhage, but treatment to control seizures or other neurological complications also may be considered. There are several potential treatment options for brain AVM. The radiation is most powerful where all the beams intersect. Individual radiation beams are too weak to hurt the brain tissue they travel through on the way to the target. MRI also provides information about the exact location of the brain AVM and any related bleeding in the brain, which is important for determining treatment options.Ī dye may also be injected to see the blood circulation in the brain (magnetic resonance angiography. MRI is more sensitive than CT and can show more subtle changes in brain tissue associated with a brain AVM. MRI uses powerful magnets and radio waves to create detailed images of the brain. The dye allows the arteries feeding the AVM and the veins draining the AVM to be viewed in greater detail. Sometimes a dye is injected through a tube into a vein for the CT scan (computerized tomography angiography). A CT scan uses a series of X-rays to create a detailed cross-sectional image of the brain. A dye is injected into the blood vessels of the brain to make them visible under X-ray imaging.Ĭomputerized tomography (CT) scan. In this test, a long, thin tube (catheter) is inserted into an artery in the groin or wrist and is threaded to the brain using X-ray imaging. Cerebral angiography reveals the location and characteristics of the feeding arteries and draining veins, which is critical to planning treatment. Also known as cerebral arteriography, this is the most detailed test to diagnose a brain AVM. Tests used to diagnose brain AVMs include:Ĭerebral angiography. ![]()
