Detection of reverse flow by duplex ultrasonography in orthostatic hypotension.
BACKGROUND AND PURPOSE The aim of this study is to elucidate the effect of orthostatic hypotension on changes in cerebral blood flow. METHODS Blood flow velocities of both the common carotid artery and vertebral artery were measured using duplex ultrasonography in 12 patients: 6 with familial amyloidotic polyneuropathy, 3 with Shy-Drager syndrome, 2 with pandysautonomia, and 1 with senile ort...
متن کاملAccess site complications following cardiac catheterization assessed by duplex ultrasonography.
Access site complications are major source of morbidity following cardiac catheterization. Their incidence varies in the literature because of multiple definitions and methods of determining the presence of particular complication. The aim of this prospective study was to determine the incidence of access site complications following cardiac catheterization using arterial duplex ultrasonography...
متن کاملDuplex ultrasonography arteriography as first-line investigation for peripheral vascular disease.
INTRODUCTION The gold standard for evaluation of the lower extremity arterial tree is catheter angiography. Duplex arterial-occlusive imaging or duplex ultrasonography arteriography, a noninvasive technique, is used as the first-line investigation in patients with peripheral vascular disease at our centre. Based on the results of duplex imaging, patients who require angiographic intervention th...
متن کاملestimation of carotid artery pulse wave velocity by doppler ultrasonography
background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...
متن کاملEstimation of Fetal Weight by Clinical Methods and Ultrasonography and Comparing With Actual Birth Weight
Introduction: Assessment of fetal weight is a vital factor in antenatal care, not only in the management of labor and delivery but also in identifying fetal weight disorders. Objective: This study compares the accuracy of clinical methods and ultrasonography in Estimating Fetal Weight (EFW) with Actual Birth Weight (ABW) in term pregnant women. Materials and Methods: This diagnostic test eval...
