DESCRIPTION Update of the 1996 U.S. Preventive Services Task Force statement about screening for asymptomatic carotid artery stenosis (CAS) in the general population. METHODS The U.S. Preventive Services Task Force examined the evidence on the natural history of CAS; systematic reviews of the accuracy of screening tests; observational studies of the harms of screening and treatment of asympto...

Detecting Carotid Occlusive Disease by Thermography • The ability of facial thermography to detect disease in the internal carotid artery was evaluated. Unilateral forehead cooling of 0.7°C or greater was observed in 57% of 30 cases with angiographically proved stenosis. Two provocative tests, facial cooling and a head clamp, increased the sensitivity rate to 83%. The greatest overall sensitivi...

Importance Carotid artery stenosis is atherosclerotic disease that affects extracranial carotid arteries. Asymptomatic refers to in persons without a history of ischemic stroke, transient attack, or other neurologic symptoms referable the The prevalence asymptomatic low general population but increases with age. Objective To determine if its 2014 recommendation should be reaff...

In 38 patients who underwent cerebrovascular evaluation followed by angiography the Doppler ultrasound scanning technique was found to be an excellent screening procedure for detecting marked stenosis (>50%) or occlusion of the internal carotid artery (93% correlation). It is noninvasive, easily reproducible and can be performed by a qualified technician. The major problems are: the inability t...

In 38 patients who underwent cerebrovascular evaluation followed by angiography the Doppler ultrasound scanning technique was found to be an excellent screening procedure for detecting marked stenosis (greater than 50%) or occlusion of the internal carotid artery (93% correlation). It is noninvasive, easily reproducible and can be performed by a qualified technician. The major problems are: the...

OBJECTIVES To evaluate a simplified ultrasound protocol for the exclusion of clinically significant carotid artery stenosis for screening purposes. MATERIAL AND METHODS A total of 9,493 carotid arteries in 4,748 persons underwent carotid ultrasound examination. Most subjects were 65-year-old men attending screening for abdominal aortic aneurysm. The presence of a stenosis on B-mode and/or a m...

INTRODUCTION Majority of stroke is due to ischemic infarction and occurs in carotid artery territory. The extra cranial parts of carotid arteries are the common sites for the atherosclerotic plaque formation. Ultrasonography is the first line of investigation for screening of the carotid artery diseases to localize and characterize the plaques. Objective was to study the morphological changes i...

BACKGROUND Imaging techniques to identify subclinical atherosclerosis are becoming more widespread, but few data exist regarding their influence on patient or physician behavior. We evaluated the impact of ultrasound screening to identify carotid artery plaques on physician treatment plans and patient motivation. METHODS Subjects included asymptomatic patients without known vascular disease w...
