Carotid endarterectomy without angiography

Carotid endarterectomy without preoperative angiography is a viable alternative that avoids the risk of angiography and potentially reduces the overall morbidity and mortality associated with the workup of patients with carotid artery disease and surgical management. The success of this approach is dependent upon the accuracy of the history and physical examination, acquisition of a CT head scan, and the validity of the duplex scan in a given laboratory.
