​

When you are diagnosed with an AVM a decision for treatment will be determined based on the benefits and risks of the treatment. 

 

The main treatment for an AVM is surgery. It may be recommended if the patient is at risk of a bleed. Surgery may completely remove an AVM and is usually performed when the AVM is small and the location is where a surgeon can remove it without causing significant damage to the brain tissues. 

​

Another type of surgery for an AVM is called an Endovascular Embolization. The surgeon threads a catheter through the arteries to the AVM and then a substance is injected to create an artificial blood clot in the middle of the AVM to temporarily reduce the blood flow. This may also be done before another type of surgery to help reduce the risk of complications during surgery. 

​

Radiosurgery is sometimes used to treat small AVM's that have not ruptured.
