[Partial aplasia of the right internal carotid artery with an unusual collateral circulation below the hypophysis (author's transl)].
A case of partial aplasia of the right internal carotid artery with an unusual artery passing through the skull base below the hypophysis is described. An association between the presence of this vessel and recurring abnormalities of eye movements with alternating ptosis is assumed. The ontogeny and phylogeny of this collateral artery are discussed.
