abstract background: transcranial doppler ultrasonography results have not been previously studied in among iranian sickle cell anemia patients. the present study was performed to evaluate the pattern of intracranial flow velocities among iranian children with sickle cell anemia and the hematological parameters that can affect the time-averaged mean of maximum velocity in major intracranial art...

background: behçet’s disease (bd) is a multisystemic inflammatory vasculitis of unknown etiology, and vasculitis being its major pathological feature. objectives: we studied the prevalence of microembolic signals (mes) in patients with diagnosis behçet's disease. we also tried to determine the frequency of mes in bd patients with or without neurological involvement. materials and methods: ...

background: stroke is a multifactorial disorder, the most common cause being arterial occlusion. transcranial doppler ultrasonography (tcd) is a common non-invasive method available for assessment the arterial blood flow of the brain. objective: assessment the hemodynamic parameters of cerebral arteries, using tcd device in patients suffering ischemic stroke. materials and methods: this descrip...

conclusion following splenectomy, thrombocytosis can predispose the patients to an increase in cerebral blood velocities more than respected with anemia. but by transcranial doppler ultrasonography no evidence of significant stenosis were found in intracerebral arteries to conclude that the beta-thalassemia major patients were more prone to the development of stroke secondary to this abnormalit...

background: the goal of this study was to determine the reliability of tcd in evaluation of vertebrobasilar arteries in comparison with brain mra in patients suffering from acute vertebrobasilar stroke. methods: samples were patients with definite clinical diagnosis of vertebrobasilar stroke. for all patients brain mri, mra and tcd were performed during the first 48 hours of admission. basilar ...

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...
