Embolization in the Head and Neck

In this article, we review current practices in therapeutic embolization of the head and neck. Major applications including vascular malformations, highly vascular tumors, trauma, and other sources of hemorrhage are discussed. We emphasize the importance of a thorough knowledge of head and neck vascular anatomy, especially of potential connections to critical territories not intended for embolization. The choice of embolic agent and its effect on safety and efficacy of treatment are presented.
