Transcranial Doppler ultrasound is capable of detecting microembolic material, both gaseous
and solid, within the intracranial cerebral arteries. To avoid discrediting this promising and …

Carotid artery disease is common and increases the risk of stroke. However, there is wide
variability on the severity of clinical manifestations of carotid disease, ranging from …

In this update, the main clinical applications of transcranial Doppler ultrasonography are
reassessed. A specific format for technology assessment, personal experience, and an …

BACKGROUND: Much attention in the literature has focused on the relationship between
perioperative microemboli during cardiac and vascular surgery and postoperative cognitive …

Objectives: To investigate whether atherosclerosis of the ascending aorta, internal carotid
arteries, and coronary arteries is predictive of postoperative delirium in subjects undergoing …

• To characterize cognitive impairments following multiple subcortical lacunar infarcts (lacunes),
we prospectively compared the neuropsychological performance of 11 subjects with …

Background and Purpose— Detection of an intracardiac shunt is frequently sought during
the evaluation of patients with cryptogenic ischemic stroke and agitated saline intravenous …

High-intensity transient signals detected by transcranial Doppler sonography have been
associated with particulate cerebral emboli. Their clinical correlates are poorly understood. This …

Purpose: The purpose of this study is to characterize microembolic signals (MS) that occur
during the various phases of carotid endarterectomy (CEA) and to consider their relationship …
