How information is presented to a patient has a lot to do with what choices they make for treatment of carotid artery lesions. When subjects were given descriptively rather than statistically, they tended to choose surgical remedies. There are many screens for arteriosclerosis that lead to more surgical business. In asymptomatic patients the carotid ultrasound (CUS) should not be done because it leads to too many procedures that are unnecessary and associated with worse outcomes than if no surgery is done.
Low cost screening panels are promoted by people wanting more business.
