Source of microembolic signals in patients with high-grade carotid stenosis.
BACKGROUND AND PURPOSE In patients with both symptomatic and asymptomatic carotid artery stenoses, the relationship between carotid plaque characteristics and transcranial Doppler (TCD)-detected microembolic signals (MES) is unclear. The purpose of this study was to examine the relationship between macroscopically described plaque characteristics and MES in patients undergoing carotid endartere...
متن کاملSymptomatic Patients With High-Grade Carotid Stenosis
Background and Purpose The importance of carotid plaque ulceration as a cause of cerebral ischemic symptoms remains uncertain. Moreover, its prominence in symptomatic patients with severe carotid stenosis is unknown. Methods The association between angiographically denned plaque ulceration and risk of subsequent stroke was assessed using Cox proportional hazards regression in 659 patients with ...
متن کاملMicroembolic signals and carotid plaque characteristics in patients with asymptomatic carotid stenosis.
OBJECTIVE To investigate the association between carotid plaque characteristics and the occurrence of cerebral microemboli signals (MES) and subsequent ischemic events in patients with asymptomatic carotid stenosis (ACS). DESIGN Sixty-two asymptomatic patients with 50-99% carotid stenosis underwent transcranial Doppler (TCD) monitoring to determine the relationship between MES and plaque char...
متن کاملCarotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
متن کاملCerebral hemodynamics in asymptomatic and symptomatic patients with high-grade carotid stenosis undergoing carotid endarterectomy.
BACKGROUND AND PURPOSE Asymptomatic patients with carotid stenosis benefit less from carotid endarterectomy (CEA) than symptomatic patients because the risk of embolic events is lower, but it is not known whether the hemodynamic effect of CEA is different between the groups. We evaluated hemodynamics of symptomatic and asymptomatic patient groups before and after CEA. METHODS Forty-six indepe...
