Cerebrovascular reactivity is the change in cerebral blood flow in response to a vasodilatory
or vasoconstrictive stimulus. Measuring variations of cerebrovascular reactivity between …

Background and Purpose—Impairments in cerebrovascular reserve (CVR) have been
variably associated with increased risk of ischemic events and may stratify stroke risk in …

Cross-sectional studies suggest that impaired cerebral haemodynamics is associated with
symptomatic status in patients with carotid stenosis and occlusion, but there is relatively little …

Objective: To review the use of transcranial Doppler ultrasonography (TCD) and transcranial
color-coded sonography (TCCS) for diagnosis. Methods: The authors searched the literature …

ContextStandards for treating patients with asymptomatic carotid artery stenosis have been
difficult to establish because of the lack of evidence for factors influencing these patients' …

Background and Purpose—In carotid disease, infarcts can occur in the cortical as well as
internal watershed (WS), or both. Better understanding the pathophysiology of WS infarcts …

Article abstract Stenosis or occlusion of the major arteries of the head and neck may cause
hemodynamic impairment of the distal cerebral circulation. Hemodynamic factors may play …

Background and Purpose—Evidence suggests that an alteration in cerebral hemodynamics
plays a relevant role in the occurrence of stroke in patients with carotid occlusion. The …

Background and Purpose—The importance of hemodynamic parameters for predicting
outcome in patients with occlusive carotid disease remains controversial. The present study …

Background and Purpose—Blood pressure lowering in patients with a previous transient
ischemic attack (TIA) or stroke reduces the risk of recurrent stroke and coronary vascular …
