Intracranial atherosclerosis, one of the leading causes of ischemic stroke, is associated with an increased risk for recurrent stroke and dementia. Individuals of Asian, Hispanic, and African American ancestry are especially affected.
Atherosclerosis is often cited as the most common cause of extracranial carotid artery aneurysms, accounting for anywhere between 34% and 70% in published series. Often, these aneurysms occur at or near the carotid bifurcation and are typically fusiform, although saccular aneurysms can also occur in this location.4 These aneurysms are found along the common or internal carotid artery but rarely at the carotid bulb (Fig 1). The patients often have severe hypertension.5 The male-to-female ratio is 1.9:1, in contrast to aortic aneurysms, where the ratio is more heavily weighted towards males.he endovascular approach offers advantages in other situations where open access to the distal extent of the aneurysm is difficult or neck radiation leads to concerns about wound healing. This article outlines the etiology, new diagnostic modalities, and treatment of aneurysms of the carotid artery.
