The ascending pharyngeal artery, the smallest branch of the external carotid, is a long, slender vessel, deeply seated in the neck, beneath the other branches of the external carotid and under the Stylopharyngeus.

Summary: 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.

Course

It arises from the back part of the external carotid, near the commencement of that vessel, and ascends vertically between the internal carotid and the side of the pharynx, to the under surface of the base of the skull, lying on the Longus capitis.
