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...

background: to determine whether islamic fasting would change cerebral blood flow during ramadan. methods: the study group comprised 20 subjects (16 males and 4 females) on a regimen of 1 month food and water intake restriction, according to islamic fasting ritual. subjects were evaluated for cerebral bolo flow through a middle cerebral artery (mca) by means of transcranial doppler (tcd), the d...

We describe the use of serial transcranial Doppler studies to evaluate neurovascular disease in three girls presenting with acute stroke due to primary cerebral vasculitis (n = 2) and West Nile vasculitis (n = 1). Correlation of abnormal findings on transcranial Doppler sonography was compared with those of MR angiography and conventional angiography in each child. All three girls had left midd...

background: an imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. the purpose of this study was to determine the transcranial doppler sonography (tds) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. methods: this study was carried out on 46 pa...

BACKGROUND AND PURPOSE Transcranial Doppler sonography is of established value in the detection and monitoring of middle cerebral artery vasospasm. Little information exists on the utility of transcranial Doppler for detection of posterior circulation vasospasm. METHODS Cerebral angiography and conventional hand-held transcranial Doppler sonography were compared to determine sensitivity and s...

BACKGROUND AND PURPOSE Transcranial Doppler is a useful ancillary test for brain death confirmation because it is safe, noninvasive, and done at the bedside. Transcranial Doppler confirms brain death by evaluating cerebral circulatory arrest. Case series studies have generally reported good correlations between transcranial Doppler confirmation of cerebral circulatory arrest and clinical confir...

The performance of transcranial Doppler in the detection of anterior cerebral artery vasospasm and vasospasm in patients after subarachnoid haemorrhage was analysed. Transcranial Doppler and cerebral angiography were performed within the same 24 hours on each of 41 patients with acute subarachnoid haemorrhage. Sensitivity and specificity of transcranial Doppler to classify middle cerebral arter...

INTRODUCTION We describe the case of a 79-year-old Caucasian Italian woman with a transient basilar occlusion monitored by transcranial Doppler, with subsequent recanalization and clinical shrinking deficit. This is the first case of transient basilar occlusive disease diagnosed and monitored by transcranial Doppler. This case is important and needs to be reported because transient basilar occl...
