[Therapy of extracranial carotid artery aneurysms--literature review].

Extracranial carotid artery aneurysms are unusually rare. Their aetiology and clinical picture have significant meaning for their recognition, with the majority involving the common carotid artery--ACC. Approximately one third of these lesions are confined to the ICA, with an equal distribution between the proximal, middle, and distal segments. Nonoperated treatment is associated with a high risk of stroke compare to surgical, wich is think as necessary from most authors, because of the high level of neurologic symptomatic in the studies. Surgical treatment is used for prevention from cerebrovascular deficit.
