BACKGROUND AND PURPOSE Doppler sonography of the carotid arteries is routinely performed before catheter angiography, and its results may bias the subsequent interpretation of angiograms. We attempt to establish that Doppler sonography may show an exaggerated degree of carotid stenosis, introducing bias to the evaluation of carotid stenosis by subsequent catheter angiography. METHODS Angiogra...

OBJECTIVE It is well known that the presence of carotid artery stenosis increases the risk of perioperative stroke in patients undergoing cardiac surgery with cardiopulmonary bypass. Although off-pump coronary artery bypass grafting (CABG) can avoid the adverse effects of cardiopulmonary bypass, the influence of carotid artery stenosis on the incidence of stroke in patients undergoing off-pump ...

Objective: We report the “sheath pull-through technique” for stenting of common carotid artery stenosis (CCAS).

To the Editor: The optimal method for measurement of carotid stenosis remains something of an enigma. Large randomized control trials in symptomatic and asymptomatic carotid stenosis have been based on standardized measurements of carotid stenosis derived from digital subtraction angiography and/or duplex ultrasound. Accordingly, there have been various methods used to measure percent stenosis ...

CT scan and MRI are useful for evaluating the question of cerebral infarction which may occur as a consequence of carotid artery stenosis. Infarctions related to internal carotid artery stenosis may be deep, subcortical, or cortical. However, carotid stenosis may exist in the absence of infarction on MRI and CT. The definition of asymptomatic or symptomatic carotid artery stenosis is based upon...

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...

BACKGROUND AND PURPOSE The relation between anterior ischemic optic neuropathy and carotid artery atherosclerotic disease is unclear. We studied patients with anterior ischemic optic neuropathy to determine if they had an increased occurrence of carotid artery stenosis. METHODS Fifteen consecutive patients with anterior ischemic optic neuropathy were evaluated prospectively for cervical carot...

BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the association between the extent of coronary artery disease assessed by the Gensini score and/or the SYNTAX score and the significant carotid stenosis in patients undergoing coronary artery bypass grafting (CABG). SUBJECTS AND METHODS A total of 225 patients who had carotid doppler ultrasonography prior to CABG were included re...

BACKGROUND Uncertainty exists over whether listening for carotid bruits as part of the clinical examination is informative in terms of predicting the presence or severity of carotid stenosis. AIM We sought to undertake a comprehensive meta-analysis and meta-regression of all studies to date that have assessed the relationship between a carotid bruit and severity of degree of stenosis. METHO...

Carotid artery stenosis is a notable cause of ocular ischemic disease. To analyze the ocular ischemic diseases caused by carotid artery stenosis and to seek effective treatment, a retrospective review of 182 patients with carotid artery stenosis was performed. These patients were administered medical treatment, carotid artery stenting (CAS) or carotid endarterectomy (CEA) and the curative effec...
