Anatomical terminology

It usually arises from theexternal carotid artery,[1]but can arise from either theinternalorexternal carotid arteryor serve as ananastomosisbetween the two.[2]

The eponym, Vidian artery, is derived from the Italian surgeon and anatomistVidus Vidius.[3]

From external carotid artery

edit

In this case; the artery passes backward along the pterygoid canal withthe corresponding nerve.It is distributed to the upper part of thepharynxand to theauditory tube,sending into thetympanic cavitya small branch which anastomoses with the othertympanic arteries.

It can end in theoropharynx.[4]

From internal carotid artery

edit

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.
