Renal artery stenosis: evaluation with colour duplex ultrasonography.
BACKGROUND Detection of renal artery stenoses (RAS) by means of duplex Doppler ultrasound with direct scanning of the main renal arteries is subject to numerous limitations. Using semiquantitative analysis of the Doppler curve, which can be recorded from intrarenal arteries, it is possible to detect RAS unaffected by the problems of direct Doppler scanning of the renal arteries. METHODS Both ...
متن کاملTreatment of atherosclerotic renal artery stenosis.
The increasing prevalence of atherosclerotic renal artery stenosis (ARAS) has prompted in recent years a more aggressive treatment of this condition for reducing BP and for preserving the jeopardized renal function. Percutaneous transluminal renal angioplasty (PTRA), alone or in conjunction with stent implantation, may be useful for both these goals. However, despite the methodological improvem...
متن کاملDuplex ultrasonography for the detection of vertebral artery stenosis
OBJECTIVES Vertebrobasilar stenosis is frequent in patients with posterior circulation stroke and it increases risk of recurrence. We investigated feasibility of duplex ultrasonography (DUS) for screening for extracranial vertebral artery stenosis and compared it with CT angiography (CTA). MATERIALS AND METHODS We gathered data on 337 consecutive patients who had DUS because of posterior circ...
متن کاملAtherosclerotic renal artery stenosis: overtreated but underrated?
Despite evidence of only moderate clinical benefit, application of renal endovascular stent procedures has increased at least four-fold in the past decade. Medicare is reviewing national coverage regarding reimbursement, questioning whether outcome data warrant many of these procedures. Several prospective, randomized trials are now in progress to compare outcomes with optimized medical therapy...
متن کاملProspective study of atherosclerotic disease progression in the renal artery.
BACKGROUND The aim of this study was to determine the incidence of and the risk factors associated with progression of renal artery disease in individuals with atherosclerotic renal artery stenosis (ARAS). METHODS AND RESULTS Subjects with >/=1 ARAS were monitored with serial renal artery duplex scans. A total of 295 kidneys in 170 patients were monitored for a mean of 33 months. Overall, the...
