Some people with carotid artery stenosis may experience dizziness, fainting and blurred vision which may be signs of the brain not receiving enough blood.[radiologyinfo.org].On the other hand, the Asymptomatic Carotid Atherosclerosis Study (ACAS) has presented slightly different rates, with the carotid endarterectomy (CEA) for asymp tomatic carotid artery stenosis had not been proved/l.12 the Asymptomatic Ca rotid Atherosclerosis Study (ACAS) was initiated in 1987.13 The ACAS is an in Executive Committee for the Asymptomatic Carotid Atherosclerosis Study.To determine whether the addition of carotid endarterectomy to aggressive medical management can reduce the incidence of cerebral infarction in patients with asymptomatic carotid artery stenosis.

CEA in asymptomatic patients with silent cerebral in-farctions. Brott et al.  also found no association be-tween silent infarcts and the degree of stenosis in the ACAS study. In 1995 the Asymptomatic Carotid Atherosclerosis Study (ACAS) demonstrated that patients with asymptomatic carotid artery stenosis of 60 or greater reduction in diameter benefited from endarterectomy, having a reduced 5-year risk of ipsilateral stroke 4. Background: The role of carotid endarterectomy (CEA) for Because of the impressive results of CEA for symptom- asymptomatic carotid artery stenosis (aCAS) remains a mat- atic disease, studies on the effect of CEA for asymptom- ter of debate. The current study shows that subgroups of patients with asymptomatic carotid artery stenosis with different plaque characteristics can be identied based on reportedObjectives: Optimal surgical treatment of patients with asymptomatic carotid artery stenosis (ACAS) remains a matter of debate. The Asymptomatic Carotid Atherosclerosis Study (ACAS) 12 and ACST studies both compared carotid endarterectomy (CEA)The causes and risk of stroke in patients with asymptomatic internal carotid artery stenosis.

Asymptomatic carotid artery stenosis Asymptomatic stenosis without high-grade contralateral carotid stenosis or contralateral occlu-sion AsymptomaticWhile earlier studies revealed no bene-fit of operative treatment, the Asymptomatic Carotid Athero-sclerosis Study (ACAS) demonstrated This study was done to determine the prevalence of asymptomatic carotid artery stenosis (ACAS) among patients with severe peripheral vascular disease (PVD).

JAMA , 273(8): Fauci, A.S et.al. Harrisons Principles of Internal Medicine, 17th ed. The Asymptomatic Carotid Atherosclerosis Study (ACAS) results suggest that carotid endarterectomy combined with aspirin and riskand risk factor reduction alone in preventing ipsilateral stroke in asymptomatic patients with diameter stenosis of the carotid artery of 60 or more. The last step in the cycle is the comparison of this estimate of effectiveness with the efficacy results from the ACAS study.Endarterectomy for asymptomatic carotid artery stenosis.

Back to Top. Signs and Symptoms. Carotid artery stenosis may be entirely asymptomatic.Carotid endarterectomy for asymptomatic people was studied in the Asymptomatic Carotid Atherosclerosis Study (ACAS) and the Asymptomatic Carotid Surgery Trial (ACST). Results from the ACAS group have recently become available and suggest that, for internal carotid artery stenosis > 60 in asymptomatic patients, endarterectomy is beneficial."3 This is the firststenosis. Stroke 199122:1229. 11 Mayo Asymptomatic Carotid Endarterectomy Study Group. The workup for a patient who presents with an asymptomatic or incidental carotid artery stenosis should be systematic.In the ACAS study, confirmatory carotid angiography performed in patients with high-grade carotid stenosis on duplex criteria was associated with a 1.2 risk of stroke. Multicenter randomized studies of carotid endarterectomy (CEA) for carotid artery disease, including Asymptomatic Carotid Artery Stenosis (ACAS) and Asymptomatic Carotid Surgery Trial (ACST) demonstrated a positive statistically significant difference when CEA was utilized stenosis. Two randomized controlled trials, the Asymptomatic. Carotid Atherosclerosis Study (ACAS) in 1995.129 patients for a still asymptomatic study artery (stenosis. median: 85 ECST interquartile range: 75-90) because. the clinician in charge or the patient requested it. The Asymptomatic Carotid Artery Study (ACAS) was a well-conducted study that assessed carotid endarterectomy (CEA) in asymptomatic carotid artery stenosis (>60) for stroke prevention.4 A total of 1,662 patients were randomized to CEA or medical therapy. Importantly, ACAS and ACST set an ambitious 1.5 and 3 surgical morbidity and mortality standard for CEA treatment of asymptomatic carotid artery disease.Finally, current medical therapy alone for asymptomatic severe carotid stenosis was not addressed by this study.

Severity of asymptomatic carotid stenosis and risk of ipsilateral hemispheric ischaemic events: results from the ACSRS study.

Carotid artery stenosis is a narrowing or constriction of any part of the carotid arteries, usually caused by atherosclerosis.
