Abstract
Aneurysms of the internal carotid artery (ICA) are subdivided according to their location along the ICA into proximal or paraclinoid aneurysms, aneurysms of the middle segment, and terminal aneurysms. Aneurysms may be related to branches of the ICA—that is, the ophthalmic artery, the posterior communicating artery (Pcom), or the anterior choroidal artery (AChA)—but a considerable proportion are unrelated to side branches. Aneurysms of the ICA can reach giant size and present with optic nerve compression.
Very small, blister-like aneurysms that present with subarachnoid hemorrhage (SAH) typically also occur on the ICA. Although surgical management using wrapping techniques is possible, the trend in the literature indicates a clear shift toward endovascular management of blister-like ICA aneurysms using stents or flow diverters, so these aneurysms are not considered in this chapter.
