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.
Carotid atherosclerosis is one of the main risk factors for ischaemic cerebrovascular events (CVEs). Carotid aherosclerosis causes about 90% of carotid artery stenosis but other much less common causes include aneurysms, arteritis, carotid dissection, coils and kinks, fibromuscular dysplasia and vasospasm. The area of the carotid artery most commonly affected by atherosclerosis is the bifurcation of the common carotid artery. Carotid endarterectomy is strongly recommended for severe symptomatic stenosis but not routinely recommended for asymptomatic patients or lesser degrees of stenosis.
