Angioplasty And Stenting

Incidental findings pose considerable management dilemmas for the treating physician and psychological burden for the respective patient. With an aging population, more patients will be diagnosed with asymptomatic internal carotid artery stenosis. Patients will have to be counseled with regard to treatment options according to their individual risk profile and according to professionals' knowledge of evidence-based data derived from large randomized control trials. Treatment consensus has long been lacking for patients with asymptomatic carotid artery stenosis prior to any randomized controlled trials. Additionally, an individual's risk profile may be hard to assess according to knowledge gained from randomized controlled trials. Moreover, while earlier studies compared carotid endarterectomy and medical therapy, in the past years, a new therapeutic modality, carotid artery angioplasty and stenting, has emerged as a possible alternative. This has been evaluated in a recent randomized controlled trial, the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST), which compared carotid endarterectomy with angioplasty and stenting in both symptomatic and asymptomatic patients. The following review summarizes current knowledge of the natural history, diagnosis, and treatment strategies to counsel patients with asymptomatic carotid artery stenosis.

Comorbidity Index

Object Several major randomized controlled trials of carotid endarterectomy (CEA) in patients with both symptomatic and asymptomatic carotid artery stenosis have addressed the net effects of CEA on the risk of stroke. However, because the risk of stroke among patients with asymptomatic carotid stenosis is relatively low, whether to treat their stenosis with CEA remains an important public health issue. Methods The authors constructed a Markov model to evaluate the effectiveness of CEA. In modeling 4 health states, the probability of transition to another state was estimated using data from major randomized controlled trials. Adopting 3 comorbidity index values for baseline analyses, the authors expressed outcomes in terms of the expected number of quality-adjusted life years (QALYs) for a hypothetical cohort undergoing CEA and another without treatment. Results In the authors' baseline analysis, CEA for asymptomatic stenosis yielded a very small benefit (0.07 QALY) for 70-year-old, normal-risk CEA candidates. Benefits decreased further, often becoming negative, as patient age, surgical risk, or comorbidity index increased. In patients with symptomatic stenosis, CEA was always more effective than conservative management, even considering variables such as comorbidities limiting life expectancy, advanced age, and increased perioperative risk. Conclusions Carotid endarterectomy for severe carotid stenosis consistently and significantly benefits patients with recent symptoms. However, surgery for asymptomatic stenosis appears justified only in carefully selected conditions: low treatment risks in relatively young individuals without any comorbidities.

Artery Disease

Carotid artery atherosclerotic disease impacts over 2 million Americans annually. Since the advent of the carotid endarterectomy by Debakey in 1953, the surgical management of carotid artery stenosis has prevented cerebrovascular accidents. The technology utilized to manage carotid artery stenosis continued to evolve with the utilization of carotid artery stenting in 1989 and more recently transcarotid artery revascularization (TCAR). This review discusses the modern management of carotid artery stenosis with an emphasis on transcarotid artery revascularization (TCAR) and reversal of flow for reversal of flow for embolic protection.

Background:A meta-analysis of randomized controlled trials (RCTs) was conducted to update the available evidence on the safety and efficacy of carotid endarterectomy (CEA) versus carotid artery stenting (CAS) in the treatment of carotid artery stenosis.Methods:A comprehensive search was performed of MEDLINE, EMBASE, CENTRAL, bibliographies of included articles and past systematic reviews, and abstract lists of recent scientific conferences. For each reported outcome, a Mantel-Haenszel random-effects model was used to calculate odds ratios (ORs) and 95% confidence intervals (CI). The I2 statistic was used as a measure of heterogeneity.Results:Twelve RCTs enrolling 6,973 patients were included in the meta-analysis. Carotid artery stenting was associated with a significantly greater odds of periprocedural stroke (OR 1.72, 95% CI 1.20 to 2.47) and a significantly lower odds of periprocedural myocardial infarction (OR 0.47, 95% CI 0.29 to 0.78) and cranial neuropathy (OR 0.08, 95% CI, 0.04 to 0.16). The odds of periprocedural death (OR 1.11, 95% CI 0.56 to 2.18), target vessel restenosis (OR 1.95, 95% CI 0.63 to 6.06), and access-related hematoma were similar following either intervention (OR 0.60, 95% CI 0.30 to 1.21).Conclusions:In comparison with CEA, CAS is associated with a greater odds of stroke and a lower odds of myocardial infarction. While the results our meta-analysis support the continued use of CEA as the standard of care in the treatment of carotid artery stenosis, CAS is a viable alternative in patients at elevated risk of cardiac complications.

Symptomatic Carotid Stenosis

Carotid artery stenting (CAS) has emerged as a potential alternative to carotid endarterectomy (CEA) for the management of carotid artery stenosis. The purpose of this article is to provide an evaluation and critical overview of the trials comparing the early and later results of CAS with CEA for symptomatic carotid stenosis. The Cochrane Controlled Trials Register, PubMed/Medline, and EMBASE databases were searched up to February 1, 2009, to identify trials comparing the long-term outcomes of CAS with CEA. The MeSH terms used were “carotid artery stenting,” “carotid endarterectomy,” “symptomatic carotid artery stenosis,” “treatment,” “clinical trial,” “randomized,” and “long-term results,” in various combinations. One single-center and three multicenter randomized studies reporting their long-term results from the comparison of CAS with CEA for symptomatic carotid stenosis were identified. All four studies independently reached the conclusion that CAS may not provide results equivalent to those of CEA for the management of symptomatic carotid stenosis. A higher incidence of recurrent stenosis and peri- and postprocedural events accounted for the inferior results reported for CAS compared with CEA. Current data from randomized studies indicate that CAS provides inferior long-term results compared with CEA for the management of symptomatic carotid artery stenosis. However, it can be argued that all of these trials were performed when both CAS equipment and CAS operators had not evolved to their current status. Given that current equipment and mature experience are required for CAS before comparing it with the current “gold standard” procedure (CEA), the results of soon-to-be reported trials (Carotid Revascularization Endarterectomy vs Stenting Trial [CREST], International Carotid Stenting Study [ICSS], or others) may alter the current impression that CAS is inferior to CEA for the treatment of symptomatic carotid stenosis.
