Measurement variability in duplex scan assessment of carotid atherosclerosis.
BACKGROUND AND PURPOSE The reproducibility of duplex scan measures of carotid atherosclerosis was evaluated as part of a study assessing the prevalence of carotid disease in elderly adults. METHODS Doppler measures of blood flow velocity were used to evaluate disease severity, and extent of carotid plaque was scored from the B-mode image. A reader assigned a grade from 0 to 3 to each of seven...
متن کاملCarotid duplex ultrasound after carotid stenting
Nature of the scan Generally, a follow-up scan after a carotid stenting procedure is performed for the surveillance of the stent, not for monitoring of the untreated contralateral carotid. Hence, if the contralateral artery is not significantly stenosed, we perform ipsilateral scans only (i.e. “targeted US”). Since the distal/cephalic end of the carotid stent can be placed well distal/cephalic ...
متن کاملComparison of oculoplethysmography/carotid phonoangiography with duplex scan/spectral analysis in the detection of carotid artery stenosis.
The accuracy of the duplex scan with spectral analysis (DS/SA) in predicting the presence of arteriographic carotid stenosis was compared to that of oculoplethysmography/carotid phonoangiography (OPG/CPA) in 234 vessels from 117 patients who had had both non-invasive studies in addition to independently interpreted arteriograms. The DS/SA with 212/234 (91%) overall correct responses was superio...
متن کاملRecanalization of intracranial carotid occlusion detected by duplex carotid sonography.
We studied three patients with internal carotid artery occlusion at the siphon who had recanalization during 1 month of close observation. Angiography and duplex carotid sonography (DCS) were repeated serially in each patient. Blood flow patterns detected by DCS were classified into three patterns by specific angiographic changes. The distal occlusive flow pattern on DCS corresponds to internal...
