TY - JOUR T1 - The vidian artery in childhood tonsillar hypertrophy. JF - American Journal of Neuroradiology JO - Am. J. Neuroradiol.

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. ER -
