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

Background and Purpose—Improved methods are required to identify the subgroup of
patients with asymptomatic carotid stenosis who will have stroke develop. It has been …

Background and Purpose—Cerebrovascular reserve (CVR) by both transcranial Doppler
ultrasonography (TCD) and quantitative cerebral blood flow (CBF) can identify subgroups of …

Objective: To assess the usefulness of transcranial Doppler CO2 reactivity (CO2R) for
prediction of ipsilateral ischemic stroke in carotid artery stenosis and occlusion with a meta …

Background and Purpose—A promising method for identifying hemodynamic impairment
that may serve as a biomarker for stroke risk in patients with intracranial stenosis is …

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 …

Background and Purpose—Patients with recently symptomatic severe carotid stenosis have
a high risk of ischemic stroke on medical treatment. The main mechanism of stroke appears …

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 …

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' …

Purpose. To investigate the association between diameter and flow velocity of the carotid
arteries and ischemic stroke. Methods. Peak systolic velocity, end diastolic velocity …
