Optimum results of the surgical treatment of carotid territory ischemia.

Abstract

Continuing controversy over the role of carotid endarterectomy in stroke prevention is based largely on reports in which high perioperative morbidity and mortality rates obviate possible long-term benefit from the procedure. The purpose of this review is to examine optimal results of carotid surgery in order to describe the potential for the procedure in stroke prevention. Optimal surgical results are compared with optimal medical results in the therapy of symptomatic patients and with optimal nonsurgical results in the therapy of asymptomatic patients. Factors common to series with excellent results, such as patient selection and operative technique, are examined, and problems such as recurrent carotid stenosis and coexisting coronary disease, which continue to plague even the best surgical series, are discussed.
