Abstract In order to prevent stroke, screening for disease‐related intracranial vasculopathy using Doppler ultrasound is recommended in sickle‐cell disease (SCD) children. How screen such adults remains largely unknown. The objective of this study was assess whether transcranial color‐coded duplex sonography (TCCD) sensitive and specific enough identify SCD adult patients with vasculopathy, com...

vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

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...

1695 he central focus of carotid Doppler sonography studies is the detection and characterization of atherosclerotic disease and stenosis. Doppler sonography samples are used primarily to quantify velocity elevations at sites of stenosis. However, more subtle clues to disease are contained in the shape and contour of the Doppler sonography waveform itself. Aberrations of waveform morphology can...

BACKGROUND AND PURPOSE The aim of this trial was to evaluate the effectiveness of extracranial-intracranial bypass with respect to vasomotor reactivity in patients with internal carotid artery occlusions and absent vasomotor reactivity, comparing them with a control group treated conservatively. METHODS To test vasomotor reactivity in 104 patients with unilateral occlusion of the internal car...
