[Large aneurysms of the internal carotid artery in its infraclinoidal intracranial portion (author's transl)].

Two new cases of large aneurysms of the infraclinoidal intracranial portion of the internal carotid artery are reported. After a survey of the literature, the authors emphasize the rarity of these malformations, their particular clinical picture with involvement of the cranial nerves. Among the various surgical techniques which were suggested for the management of these large aneurysms, the ligation of the internal carotid artery in the neck is favoured by the authors as the best procedure.
