BACKGROUND AND PURPOSE The role of carotid artery stenting (CAS) as an alternative to carotid endarterectomy in the treatment of for symptomatic carotid artery stenosis is investigated. MATERIALS AND METHODS Forty-seven patients underwent CAS over 10-year period. Forty-nine vessels were treated. Stenosis quantification was done using North American symptomatic carotid endarterectomy trial met...

BACKGROUND AND PURPOSE This study was designed to determine the prevalence of carotid stenosis and atherosclerosis in older adults with and without isolated systolic hypertension and to determine risk factors for carotid artery disease in these two groups. METHODS Duplex scans were performed on 187 participants of the Systolic Hypertension in the Elderly Program and on 187 normotensive contro...

OBJECTIVE To determine the frequency and characteristics of carotid artery stenosis in acute ischaemic stroke patients and to assess the significance of common risk factors for carotid stenosis in these patients. METHOD One hundred consecutive patients admitted with acute ischaemic stroke were included in the study. The relevant history, physical examination and laboratory investigations were...

OBJECTIVES The purpose of this study was to determine the safety of carotid artery stenting with a unique distal embolic protection system in high-risk patients with severe carotid stenosis. BACKGROUND Previous studies suggest that some patients with carotid stenosis and serious comorbid conditions are at high risk for carotid endarterectomy, and may be safely treated by carotid artery stenti...

Ipsilateral motor or sensory symptoms associated with carotid occlusive diseases are rare. We report a 52-year-old man who presented with aphasia, right hemiparesis, mild left leg weakness, and bilateral Babinski's signs. During the previous 10 days, he had experienced three episodes of left leg numbness and incoordination that occurred either alone or in association with right arm and leg weak...

background: in patients with acute stroke and middle cerebral artery (mca) stenosis, microembolic signals (mes) can predict further cerebral ischemia. therefore, this study was designed to evaluate the prevalence of mes by transcranial doppler (tcd) in patients with mca stenosis under treatment of aspirin or clopidogrel. methods: a randomized clinical trial was performed on 40 patients with acu...

INTRODUCTION Little is known about the prognosis of moderate versus critical carotid stenosis treated by carotid artery stenting (CAS). MATERIAL AND METHODS This was a retrospective analysis of a single-centre registry including 271 consecutive patients (69 ±9 years, 87% at high risk for surgery), in whom 308 procedures were performed. The study included both symptomatic (≥ 50% carotid artery...

Besides the established factors "presence of symptoms" and "degree of stenosis", plaque echolucency is considered to be associated with increased risk of stroke in patients with carotid artery disease. An evaluation was carried out as to whether the prevalence and number of microembolic signals (MES) detected by transcranial Doppler ultrasound were higher in patients with echolucent carotid pla...

While stroke is a known cause of a cognitive impairment, the relationship between a carotid artery stenosis and the cognitive function in individuals without a history of stroke is less clear. A number of risk factors for vascular disease are related to a cognitive impairment. Hypertension, diabetes mellitus, cigarette smoking, and dyslipidemia are also associated with an increased risk of caro...
