Because arteriovenous malformations (AVMs) are one of the leading causes of debilitating hemorrhagic strokes in young people, the goal of treatment is to reduce the risk of stroke. Today, there are many safe and highly effective therapies. These include surgery, radiation therapy, embolization and radiosurgery using a machine called a Gamma Knife.

• Surgery — In many cases, surgery may be recommended to completely remove your child’s AVM. In addition to conventional brain surgery, advanced, minimally invasive surgical techniques are available.
• Gamma Knife — The Gamma Knife is an advanced radiosurgery treatment for abnormal blood vessel formations, is often recommended for children with complex, deep seated or brain stem AVMs. Despite its name, it isn't a knife at all. It delivers a single, very finely focused, high dose of radiation precisely to its target, while causing little or no damage to surrounding tissue. The Gamma Knife may be used in combination with other treatments, such as surgery, or by itself as the primary therapy.
• Embolization — This technique is used to reduce blood flow to the AVM by obstructing surrounding blood vessels. During this procedure, the AVM is filled with specially designed coils, glues or spheres, which plug its vessels. As a result, blood flow is decreased, making the AVM more manageable for future procedures such as surgery.
