Carotid<unk> al<unk>  is a narrowing of the lumen of the carotid<unk> , usually by atheroma (a fatty lump or plaque causingatherosclerosis). Atheroma's may cause transient ischemic attacks (TIAs) and cerebrovascular accidents (CVAs) as it obstructs the bloodstream to the brain.  It also has the potential to generate emboli (blood clots) that obstruct the cerebral<unk> es. The narrowing can either be asymptomatic (causing no medical problems) or presents with symptoms such as TIAs and CVAs.
