Accidental microembolic signals: prevalence and clinical relevance
Background: The purpose of this study was to examine the occurrence of accidental microembolic signals (MES) and its clinical relevance in patients receiving routine transcranial Doppler (TCD) examinations. Methods: We retrospectively reviewed our institutional TCD database (from January 2007–November 2012). The arteries with positive MES, the presumed sources of emboli and the clinical backgro...
متن کاملPrevalence and frequency of microembolic signals in 105 patients with extracranial carotid artery occlusive disease.
Besides the established factors "presence of symptoms" and "degree of stenosis", plaque echolucency is considered to be associated with increased risk of stroke in patients with carotid artery disease. An evaluation was carried out as to whether the prevalence and number of microembolic signals (MES) detected by transcranial Doppler ultrasound were higher in patients with echolucent carotid pla...
متن کامل"Tail sign" associated with microembolic signals.
BACKGROUND AND PURPOSE Transcranial Doppler ultrasound (TCD) can detect circulating microembolic signals (MES). We focused our attention on tail signs (TS), a signal associated with MES that appeared as a small reversal signal after MES on the high time resolution spectral display. We examined MES and artifacts in an animal study to determine whether TS were specific changes associated with MES...
متن کاملInfluence of Clinical Parameters and Anticoagulation on Intraprocedural Cerebral Microembolic Signals during Pulmonary Vein Isolation
OBJECTIVE We had the objective to determine the impact of clinical parameters and anticoagulation status on cerebral microembolic signals (MES) during pulmonary vein isolation (PVI) for atrial fibrillation (AF). BACKGROUND Thromboembolism and stroke are the most feared complications of PVI. MES can help to evaluate embolic burden. It is unknown whether clinical parameters have an impact on em...
متن کاملStatin Pretreatment and Microembolic Signals in Large Artery Atherosclerosis.
OBJECTIVE Although statin pretreatment (SP) is associated with better outcomes in patients with acute cerebral ischemia after an ischemic stroke/transient ischemic attack, data on the underlying mechanism of this beneficial effect are limited. APPROACH AND RESULTS We sought to evaluate the potential association between SP and microembolic signal (MES) burden in acute cerebral ischemia because...
