The artery of the pterygoid canal (or Vidian artery) is an artery in the pterygoid canal, in the head.

It usually arises from the external carotid artery,{{cite web |url=http://www.medscape.com/viewarticle/494394_2 |title=Medscape |access-date=2008-03-13 }} but can arise from either the internal or external carotid artery or serve as an anastomosis between the two.{{cite web|url=http://www.jstage.jst.go.jp/article/nmc/45/9/45_470/_article |title=NMC : Vol. 45 (2005), No. 9 470-471 |access-date=2008-03-13 }}{{dead link|date=December 2016 |bot=InternetArchiveBot |fix-attempted=yes }}

The eponym, Vidian artery, is derived from the Italian surgeon and anatomist Vidus Vidius.{{cite journal |author=Tubbs RS, Salter EG |title=Vidius Vidius (Guido Guidi): 1509-1569 |journal=Neurosurgery |volume=59 |issue=1 |pages=201–3; discussion 201–3 |year=2006 |pmid=16823317 |doi=10.1227/01.NEU.0000219238.52858.47 |doi-access=free }}

From external carotid artery

In this case; 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.{{cite web|url=http://chorus.rad.mcw.edu/doc/00415.html |title=vidian artery |access-date=2008-03-13 |url-status=dead |archive-url=https://web.archive.org/web/20090530011147/http://chorus.rad.mcw.edu/doc/00415.html |archive-date=2009-05-30 }}

From internal carotid artery

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 the maxillary artery.{{Cite journal |last=Osborn |first=A. G. |date=August 1980 |title=The vidian artery: normal and pathologic anatomy |url=https://pubmed.ncbi.nlm.nih.gov/7403513/ |journal=Radiology |volume=136 |issue=2 |pages=373–378 |doi=10.1148/radiology.136.2.7403513 |issn=0033-8419 |pmid=7403513}} The artery is small and inconstant, passing through the pterygoid canal in an opposite direction to its corresponding nerve.
