Difficult anatomy: what characteristics are critical to good outcomes of either CEA or CAS?

Whether performing carotid endarterectomy or carotid stenting, patients are selected on the basis of their anatomical suitability for these procedures. The procedure is then tailored to the specific anatomy with which the patient presented. As a result, outcomes of both carotid endarterectomy and stenting are significantly influenced by anatomical considerations and good outcomes are determined, at least in part, by selecting, understanding, and managing a wide variety of anatomical presentations.
