Introduction:In this study, a non-invasive method based on consecutive ultrasonic image processing is introduced to assess time rate changes of the carotid artery wall displacement, velocity and acceleration in the longitudinal direction. The application of these parameters to discriminate healthy and atherosclerotic arteries was evaluated. Methods:Longitudinal displacement rate of common ...

BACKGROUND AND PURPOSE Traditional vascular risk factors do not completely explain the asymmetry, racial, and sex differences in carotid artery disease. Carotid anatomy and geometry may play a role in the pathogenesis of internal carotid artery (ICA) stenosis, but their effects are unknown. We hypothesized that carotid artery anatomy and geometry would be independently associated with ICA steno...

BACKGROUND AND PURPOSE We systematically compared and appraised contemporary guidelines on management of asymptomatic and symptomatic carotid artery stenosis. METHODS We systematically searched for guideline recommendations on carotid endarterectomy (CEA) or carotid angioplasty/stenting (CAS) published in any language between January 1, 2008, and January 28, 2015. Only the latest guideline pe...

Current available data do not seem to support the strategy for carotid endarterectomy prior to surgical intervention in patients with asymptomatic carotid stenosis. However, in patients with coronary artery disease, synchronous carotid endarterectomy and coronary artery bypass grafting should be considered where there is a proven surgical risk of <3% with unilateral asymptomatic stenosis >60% o...

Stroke is a known cause of cognitive impairment but the relationship between asymptomatic carotid artery stenosis and cognitive function is not clear. The main risk factors for vascular disease are also related to carotid stenosis and cognitive impairment. The association of high-grade stenosis of the internal carotid artery with cognitive impairment is related to silent embolization and hypope...

To investigate potential associations between carotid artery stenosis and cognitive impairment among patients with acute ischemic stroke and to provide important clinical implications. We measured the degree of carotid artery stenosis and recorded the Mini-Mental State Examination score (MMSE) at admission in 3116 acute ischemic stroke patients. The association between carotid stenosis and cogn...

Managing patients scheduled for cardiac surgery with significant carotid artery disease is a controversial issue that usually produces very polarized opinions, even in the literature. Discussion focuses on determining if carotid disease, concomitant with the need for coronary artery bypass, is an important etiologic factor for post-surgical stroke, or simply a marker of increased risk of vascul...

background: although the risk factors of ischemic strokes are well defined, there is slight information about their relations with the etiologies of ischemic strokes. this study investigated the distribution of ischemic stroke risk factors and their connections to diverse etiologies of cerebrovascular attack (cva) and specific ischemic regions of brain. methods: in this cross sectional study , ...

BACKGROUND AND PURPOSE It has been established that mitral annulus calcification (MAC) is an independent predictor of stroke, though a causative relationship was not proved, and that carotid artery atherosclerotic disease is also associated with stroke. The aim of this study was to determine whether there is an association between the presence of MAC and carotid artery atherosclerotic disease. ...

Doppler ultrasound is a noninvasive technique which is widely used in medicine for the assessment of blood flow in vessels. Therefore, Doppler ultrasonography is known as a reliable technique, which demonstrates the flow characteristics and resistance of internal carotid arteries in stenosis and occlusion conditions. In this study, internal carotid arterial Doppler signals recorded from 130 sub...
