Abstract

Stroke is the third leading cause of death in the United States with over 783,000 strokes reported annually.1 Over one-third of patients die and another one-third are severely disabled.The annual economic cost exceeds $30 billion.2 Randomized trials have established the efficacy of carotid endarterectomy (CEA) in the prevention of stroke for patients with high-grade carotid stenosis (CS).3–7 The advent of newer technologies and a desire for less invasive treatment have encouraged investigators to propose carotid artery stenting (CAS) as an alternative to CEA.1,8–10 Our institution1, 8,11–17 (Figure 10–1), along with others,18–22 has demonstrated that CAS is technically feasible and safe in patients with restenosis after CEA, surgically inaccessible lesions, previous radiation, or significant medical comorbidities. The 30-day stroke and death rate in 190 CAS procedures at our institution was 4.15%, indicating a competitive alternative to CEA.14 However, due to the proven efficacy of CEA, current indications for CAS have been limited to situations where CEA yields suboptimal results.13,23
