[Primary "mycotic" aneurysm of the common carotid artery. Report of one case (author's transl)].

Primary mycotic aneurysm of the common carotid artery is exceptional. The clinical characteristics are dominated by the absence of a detectable infectious cause, by the macroscopic, nonsuppurative aspect and the sudden increase in volume requiring emergency operation. The treatment of these aneurysms is surgical, but little known owing to the rareness of these cases. Reconstructive surgery gives satisfactory results. Its details are discussed in relation to the operative appearance.
