RT Journal Article SR Electronic T1 The vidian artery in childhood tonsillar hypertrophy. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 141 OP 143 VO 9 IS 1 A1 J R Jinkins YR 1988 UL http://www.ajnr.org/content/9/1/141.abstract AB Cerebral arteriography performed in two children for cerebral pathology incidentally revealed prominent arterial supply to pharyngeal tonsillar tissue arising directly from the internal carotid arteries bilaterally. Embryologic considerations seem to indicate developmental origins of this vessel from early emanations of the first fetal aortic arch. Clinical implications revolve around the possible relation of the vidian artery to serious hemorrhage during or after otherwise uncomplicated tonsillectomy.
