Vascular interventions in the head and neck region. Part 2: procedures for vessel occlusion

As a result of continuing progress in the development of intervention materials but also due to growing understanding of pathophysiological relationships, the prevalence and significance of endovascular interventions in the head and neck region have continued to increase. This applies to procedures for recanalization, which were addressed in detail in an earlier article, as well as to techniques used for vessel occlusion. This contribution first presents the techniques and materials employed in embolization in the head and neck region. Based on this description the application of endovascular procedures for vessel occlusion are explained with respect to different disease entities in the head and neck region. In this context particular attention is given to the treatment of intracranial aneurysms, cerebral arteriovenous malformations, dural AV fistulae, vascular malformations, and tumors in the head and neck region.
