Extracranial carotid and vertebral artery aneurysms

Extracranial carotid aneurysms are uncommon, and in the past their management has not always been satisfactory. These aneurysms may be caused by arteriosclerosis, infection or trauma, or they may be congenital. Neurologic symptoms are common. Surgery is recommended for symptomatic aneurysms in patients of all ages. Non-growing aneurysms in old patients can be conservatively managed. Six cases of carotid and one case of vertebral artery aneurysm are reported. The mode of clinical presentation, etiologic factors, angiographic findings and methods of management are discussed.
