Anterior internal carotid artery aneurysm

Anterior internal carotid artery aneurysm is a rare kind of aneurysm caused by atherosclerosis. This paper summarises the authors' experience with this kind of rare aneurysm. From January 2001 to December 2004, 6 cases of anterior internal carotid artery aneurysms were treated at Fujita Health University Hospital. The patients' clinical presentation, image data, treatment and outcome are described. Through the authors' limited number of cases, we concluded that all the aneurysms were located at the supraclinoid portion of the internal carotid artery. Two of our cases did not have arteriosclerosis. We used clipping and wrapping techniques to manage these easily ruptured aneurysms
