Considerable controversy exists regarding the clinical significance and appropriate diagnostic criteria for recurrent carotid stenosis after CAS. Placing a stent in the carotid artery alters its biomechanical properties and renders it less complaint. This in turn leads to elevations in velocities that do ...
Velocity criteriaIntimal hyperplasiaMorphologyCarotid stentingCarotid artery stenting (CAS) has recently emerged as a less invasive alternative to carotid endarterectomy (CEA). Carotid stenting has been demonstrated to be technically feasible and safe in high-risk patients. It has been approved as an ...

Carotid artery stenting: is there a need to revise ultrasound velocity criteria? Ultrasound (US) velocity criteria have not been well-established for patients undergoing carotid artery stenting (CAS). A potential source of error in usin... BK Lal,RW Hobson,J Goldstein,... - 《Journal of Vasc...
carotid Doppler waveforms demonstrate the characteristic spike-and-dome pattern and a high resistance signal. A very low PSV with preserved upstroke is present in the setting oflow cardiac output. Because this may mask significant carotid stenosis when only absolute velocity criteria are used, graysc...
Ultrasound velocity criteria for carotid in-stent restenosis Objective To examine duplex ultrasound (US) criteria for carotid in-stent restenosis (ISR). Background Carotid artery stent (CAS) placement is an alternati... YW Chi,CJ White,TC Woods,... - 《Catheterization & Cardiovascular Interventions...
No patient with Doppler criteria for significant stenosis had more than 50% residual stenosis. Three of nine patients who underwent follow-up angiography had stenosis of 50% or more; of these three patients, two underwent second angioplasty procedures. The peak in-stent systolic velocity or ...
Duplex Ultrasound Criteria for the Identification of Carotid Stenosis Should Be Laboratory Specific terms of their overall diagnostic performance and the optimal criteria to identify patients who have a 70% to 99% stenosis of the internal carotid artery... KM Kuntz,JF Polak,AD Whittemore,... - ...
carotid ultrasound examination results were then reviewed by two independent operators. Discrepancies between their evaluations were resolved by consensus. CAS diagnosis was made according to the peak systolic flow velocity (PSV) criteria that was published39. Briefly to say, the PSV for different ...
In advanced atherosclerosis, better information is extracted out from presurgery clinical symptoms combined with dyslipidemia evaluation and associated information from cerebral angiography, carotid duplex ultrasound, computer-assisted topographic angiography (CTA) and magnetic resonance angiography (MRA).
