Neuroradiologists generally do not fully appreciate the importance of the territory of the ascending pharyngeal artery. The ascending pharyngeal artery is a small but important artery that supplies multiple cranial nerves and anastomotic channels to the anterior and posterior cerebral circulations. Several disease processes in the head and neck involve the ascending pharyngeal artery. To evaluate and treat such diseases, it is necessary for neuroradiologists not only to know selective angiography and embolization techniques, but also the territory of the ascending pharyngeal artery, anastomoses, and vascular supply to the vasa nervorum of lower cranial nerves. Herein, the normal angiographic anatomy of the ascending pharyngeal artery, its relationship with neighboring territories, its importance in clinical situations, and research models are reviewed.
