This report reviews the literature concerning the effectiveness and risks of carotid endarterectomy, provides a comprehensive list of potential indications, and presents ratings of appropriateness and necessity of this surgical procedure by a panel of experts. The literature review covered articles published from 1966 to 1990. An "appropriate" procedure was defined as one for which the expected health benefits to an average patient exceed the expected health risks and is superior to the alternative treatments (including no treatment). Such a procedure was also defined as "necessary" when a physician is obliged to recommend it to a patient as the preferred treatment option.
