Asymptomatic carotid artery stenosis is a significant health concern, as out of the 135,701 carotid revascularizations performed in the U.S. in 2005, 122,986 (92%) were for asymptomatic carotid artery stenosis. Found insideThis book presents the new concept ‘acute cerebrovascular syndrome’ (ACVS), which includes both TIA in acute settings and AIS. For asymptomatic carotid artery stenosis patients considered high-CEA-risk because of comorbidities, vascular anatomy, or undefined reasons, CAS was endorsed in 13 guidelines (46%). They were further randomized to those who underwent carotid revascularization; CEA or carotid artery stenting (CAS) vs those that underwent medical .  I, Troitskiy Nies KPH, Smits LJM, Kassem M, Nederkoorn PJ, van Oostenbrugge RJ, Kooi ME.

Of the 58 patients, 41 were high risk while 17 were low risk. SCREENING FOR ASYMPTOMATIC CAROTID ARTERY STENOSIS INTRODUCTION Cerebrovascular disease is the third leading cause of death in the U.S.1 Approximately 500,000 Americans each year suffer a first stroke.1 The mortality rate for cerebrovascular disease has declined by nearly 70% since 1950.2 Much of the decrease is likely due to reduced cigarette smoking and improved control of hypertension.

Given this, the more recent AHA guidelines (Brott 2011) state that it is "reasonable" to perform CEA for asymptomatic patients with >70% stenosis if the surgical complication rate is "low."

Epub 2021 Jul 29. Introduction Carotid endarterectomy (CEA), carotid artery stenting (CAS) and best medical therapy (BMT) are the major treatments used for significant asymptomatic carotid artery stenosis (ACAS, ≥50%). Found insideThis major new book examines all causes of treatment-related stroke, highlighting therapeutic approaches. Of patients who had angiography, 0.4% to 1.2% had strokes as a result.8 The current review found no new studies on the harms of confirmatory testing methods.7, Quiz Ref IDThe 2014 review found 3 trials that reported on harms of CEA or CAS, most of which were conducted during the 1990s.8 Many study participants had hypertension, coronary artery disease, or diabetes.  et al; Aggressive Medical Treatment Evaluation for Asymptomatic Carotid Artery Stenosis (AMTEC) Study Group.

Between 20% and 32% of trial patients reported a history of contralateral artery transient ischemic attack, stroke, or CEA at baseline.8 Additionally, requirements for asymptomatic status differed slightly across the trials. Screening for asymptomatic carotid artery stenosis: U.S. Preventive Services Task Force recommendation statement. Of the 4 included studies, none used angiography as a reference standard and only 2 enrolled patients from the general population.8, The USPSTF found no externally validated risk stratification tools that could reliably distinguish between asymptomatic persons who have clinically important carotid artery stenosis and persons who do not, or the risk of stroke related to carotid artery stenosis.7-9, The USPSTF found no studies that directly examined the health benefits of screening with DUS.7-9, The 2014 review found 3 randomized clinical trials (n = 5226) that assessed the benefits of treating asymptomatic carotid artery stenosis (defined as stenosis ≥50%) with CEA compared with medical therapy alone over 2.7 to 9 years. For symptomatic patients with high carotid endarterectomy risk, medical treatment alone was not endorsed in any guidelines, though the possibility was considered as an alternative option in 2.  et al; US Preventive Services Task Force. In selected asymptomatic patients who are at increased risk for carotid stenosis, we suggest screening for clinically asymptomatic carotid artery stenosis as long as the patients would potentially be fit for and willing to consider carotid intervention if significant stenosis is discovered. Management of asymptomatic carotid stenosis. Asymptomatic carotid stenosis of more than 50% has an age-dependent prevalence in men of 0.5% to 5.7% and in women of 0.3% to 4.4%.

The prevalence of asymptomatic carotid artery stenosis is low in the general population but increases with age. AJNR Am J Neuroradiol. Jonas Using a reaffirmation process, the USPSTF concludes with moderate certainty that the harms of screening for asymptomatic carotid artery stenosis outweigh the benefits. US guidelines differ regarding the role of DUS screening in patients without a history of transient ischemic attack, stroke, or other neurologic signs or symptoms referable to the carotid arteries. The procedure is not described in detail here - please talk to your vascular specialist for a full description. , US Preventive Services Task Force. Asymptomatic Carotid Stenosis. Optimal treatment for clinically significant asymptomatic carotid artery stenosis remains uncertain.
