Carotid Artery Stenting Duplex ultrasound velocity criteria had not been well established for patients undergoing CAS until very recently. Two studies initially reported altered blood flow velocities after carotid stent placement. University of Washington Criteria Phases I and II I II Blackshear 1979 Fell 1981 Breslau 1982 Langlois 1983 Normal Normal 1-10% 1-15% 10-49% 16-49% 50-99% 50-99% Occluded Occluded Primary criterion: ≥50% ICA stenosis PSV ≥125 cm/s Secondary criterion: Normal vs. <50% stenosis Spectral broadening (minimal vs. complete) CAROTID DUPLEX CRITERIA Duplex Velocity Criteria for ICA Stenosis—Hoe-Chin Chua et al who do not require it. The current method of choice for non-invasive screening of the carotid artery is duplex ultrasonography.1 Although several criteria are available for diagnosing carotid stenosis, there is no consenus on the ideal criteria.

They proposed new criteria defining ISR ≥ 70% (PSV ≥350 and ICA/CCA ratio ≥ 4.75) and ISR ≥ 50% (PSV > 225 and ICA/CCA ratio ≥ 2.5). Duplex Ultrasound Velocity Criteria in Carotid Artery Stenting Patients. Incidence of in-stent restenosis after carotid artery stenting (CAS).

Spectral Doppler image confirms marked velocity elevation: PSV = 581 cm/s, end diastolic velocity (EDV) = 181 cm/s, and the PSV ratio is 8.2. All three parameters are consistent with a 70% or greater stenosis according to the Society of Radiologists in Ultrasound (SRU) consensus criteria.

analyzed velocity/angiography observations obtained primarily from procedural angiography and selected angiography performed in patients with suspected high-grade ISR during follow-up.

We previously reported the optimal DUS … The currently used carotid DUS velocity criteria overestimated the incidence of in-stent restenosis. We propose new velocity criteria for the ICA PSV of > 155 cm/s to define > or = 30% in-stent restenosis.

These changes persist during long-term follow-up and across all grades of in-stent restenosis after CAS. The proposed new velocity criteria accurately define residual stenosis >or =20%, in-stent restenosis >or =50%, and high-grade in-stent restenosis > or =80% in the stented carotid artery. Duplex velocity criteria for carotid endarterectomy Previous Article Evidence of use of multilayer flow modulator stents in treatment of thoracoabdominal aortic aneurysms and dissections Next Article Endovascular management of chronic symptomatic aortic dissection with the Streamliner Multilayer Flow Modulator: Twelve-month outcomes from the global registry Universally accepted ECA duplex velocity criteria, for the prediction of stenosis, do not exist. Methods: Consecutive patients undergoing angiography and carotid duplex assessments were compared (n = 140).
