Treatment for Arteriovenous Malformations

Most arteriovenous malformations (AVMs) are treated with microsurgical resection. The safety and efficacy of surgery is enhanced by preoperative embolization, an endovascular procedure that selectively catheterizes arteries feeding into an AVM and occludes them with particles or glue. This preoperative technique decreases the flow through an AVM and facilitates its surgical removal. While most AVMs can be treated in this manner, those that are not surgically accessible are treated with stereotactic radiosurgery, or the Gamma Knife®. This approach uses radiation targeted precisely to the AVM to induce changes in the arteries that, over time, occlude them.
