Theartery of the pterygoid canal (orVidian artery) is anartery in thepterygoid canal, in the head.
It usually arises from theexternal carotid artery,[1] but can arise from either theinternal orexternal carotid artery or serve as ananastomosis between the two.[2]
The eponym, Vidian artery, is derived from the Italian surgeon and anatomistVidus Vidius.[3]
In this case; the artery passes backward along the pterygoid canal withthe corresponding nerve. It is distributed to the upper part of thepharynx and to theauditory tube, sending into thetympanic cavity a small branch which anastomoses with the othertympanic arteries.
It can end in theoropharynx.[4]
In this case; the artery passes inferiorly through foramen lacerum towards the oropharynx, with its main trunk continuing anteriorly through the pterygoid canal to anastomose with the pterygopalatine part of themaxillary artery.[5] The artery is small and inconstant, passing through the pterygoid canal in an opposite direction to itscorresponding nerve.
