The artery of the pterygoid canal (Vidian artery) is an artery that can arise from the internal carotid (ICA) or external carotid (ECA), or serve as an anastomosis between these arteries.[1]

It more commonly arises from the ECA.[2]

The eponym derived from Vidus Vidius.[3]

[edit] From external carotid

The artery passes backward along the pterygoid canal with the corresponding nerve. It is distributed to the upper part of the pharynx and to the auditory tube, sending into the tympanic cavity a small branch which anastomoses with the other tympanic arteries.

It can end in the oropharynx.[4]

[edit] From internal carotid

The artery is a small, inconstant branch which passes into the pterygoid canal and anastomoses with a branch of the maxillary artery.
