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.

Vascular interventions in the head and neck region are becoming increasingly more important due to acquisition of knowledge on the pathophysiological principles of various vascular diseases and the development of new intervention materials. This article gives a review of the materials and techniques used in interventions in the head and neck region. Special attention is given to the description of a safety-oriented approach to avoid potentially severe complications. Based on this the value of endovascular therapeutic procedures for recanalization of various diseases will be discussed, in particular the treatment of extracranial and intracranial stenoses and the reopening of vascular occlusions in acute stroke using PTA, stents, lysis and mechanical thrombus removal.
