BACKGROUND AND PURPOSE We tested the hypothesis that transcranial Doppler embolic signal (ES) detection identifies an increased risk of ipsilateral carotid stroke or transient ischemic attack (TIA) in subjects with asymptomatic severe carotid stenosis. METHODS Subjects with duplex-determined 60% to 99% carotid stenosis, without other apparent(More)
PURPOSE Post-operatively detected transcranial Doppler (TCD) embolic signals (ES) are associated with an increased risk of carotid endarterectomy (CEA) stroke/TIA. The aims here were to quantify this risk and determine the most efficient monitoring protocol. METHODS Sequential patients undergoing CEA (enrolled in a randomised, blinded, placebo-controlled(More)
OBJECTIVES Transcranial Doppler (TCD) monitoring for micro embolic signals (MES), directly after carotid endarterectomy (CEA) may identify patients at risk of developing ischaemic complications. In this retrospective multicentre study, this hypothesis was investigated. METHODS Centres that monitored for MES after CEA were identified by searching Medline.(More)
One hundred fifty patients undergoing carotid endarterectomy were randomly assigned to receive intravenous 10% dextran 40 or placebo. Transcranial Doppler monitoring of the ipsilateral middle cerebral artery 0 to 1 hour postoperatively detected embolic signals in 57% of placebo and 42% of dextran patients, with overall embolic signal counts 46% less for(More)
BACKGROUND This study was undertaken to elucidate the natural history of high intensity transient signals (HITS) after carotid endarterectomy (CEA) and to determine whether this differs between patients with and without HITS detected preoperatively. METHODS A 30-min transcranial Doppler (TCD) recording was performed to detect HITS in 141 patients at 0-1(More)
BACKGROUND AND PURPOSE High numbers of microembolic signals (MES) have been associated with increased risk of postoperative stroke after carotid endarterectomy (CEA). We sought to identify factors predictive of postoperative MES. METHODS Transcranial Doppler monitoring of the ipsilateral middle cerebral artery for MES was performed for 30 minutes during(More)
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(More)
