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 aim of this study is to determine the frequency of intracranial artery stenosis in patients with acute ischemic stroke in iran. methods: a total of 169 patients with acute ischemic stroke were eligible to participate and were enrolled in this study from january 2012 to february 2013. all the patients were admitted to the nemazee ‎hospital, affiliated to shiraz university of medi...

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...

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...

Transcranial Doppler ultrasonography has been used to detect microemboli in the middle cerebral artery during orthopedic surgery. We conducted a comprehensive systematic literature review of transcranial Doppler ultrasonography in orthopedic surgery to evaluate its status in this setting. Fourteen studies were selected for qualitative analysis. The highest number of patients studied was 45; emb...

Background: β-thalassemia, a severe form of anemia, is an inherited blood disorder characterized by growth retardation, splenomegaly, and bone abnormalities. Complications related to treatment-induced iron overload also affect the quality of life of patients with major β-thalassemia. Some recent studies indicated cerebral hemodynamic disorders and increased risk of stroke in these patients. The...
