Microembolic signals in acute posterior circulation cerebral ischemia: sources and consequences.
BACKGROUND AND PURPOSE The clinical significance of microembolic signals (MES) in the posterior circulation remains unclear. The aim of this study was to investigate the sources and consequences of MES in acute posterior circulation cerebral ischemia. METHODS We evaluated a total of 140 consecutive patients (93 males, mean age 62.9 years) who had acute posterior circulation cerebral ischemia....
متن کاملApplications and advantages of power motion-mode Doppler in acute posterior circulation cerebral ischemia.
BACKGROUND AND PURPOSE Evaluation of posterior circulation with single-gate transcranial Doppler (TCD) is technically challenging and yields lower accuracy parameters in comparison to anterior circulation vessels. Transcranial power motion-mode Doppler (PMD-TCD), in addition to spectral information, simultaneously displays in real-time flow signal intensity and direction over 6 cm of intracrani...

متن کاملfrequency of microembolic signals in patients with acute ischemic stroke in middle cerebral artery territory treated with aspirin or clopidogrel.
background: in patients with acute stroke and middle cerebral artery (mca) stenosis, microembolic signals (mes) can predict further cerebral ischemia. therefore, this study was designed to evaluate the prevalence of mes by transcranial doppler (tcd) in patients with mca stenosis under treatment of aspirin or clopidogrel. methods: a randomized clinical trial was performed on 40 patients with acu...
