When the old DUS velocity criteria for nonstented carotid arteries were applied, 54% of patients had ≥ 30% restenosis (PSV of > 120 cm/s), but when our new proposed DUS velocity criteria for

2020-12-01 · Standardization of carotid duplex criteria should result in more consistent reporting and

ICA PSV is 125-230 cm/sec and plaque is visible sonographically. additional criteria include ICA/CCA PSV ratio of 2.0-4.0 and ICA EDV of 40-100 cm/sec. ≥70% ICA stenosis but less than near occlusion. 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 ≥ 30% in-stent restenosis.

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). ICA, common carotid artery (CCA), and ECA peak systolic velocities (PSVs) were recorded. ECA/CCA PSV ratio was calculated.

ICA PSV is <125 cm/sec and no plaque or intimal thickening is visible sonographically; additional criteria include ICA/CCA PSV ratio <2.0 and ICA EDV <40 cm/sec <50% ICA stenosis 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.

We propose new velocity criteria for the ICA PSV of > 155 cm/s to define ≥ 30% in-stent restenosis. Duplex ultrasound velocity criteria for the diagnosis and grading of stenosis severity The test allows stratification of the degree of carotid artery stenosis on the basis of grayscale and Doppler velocity results into the following strata: normal (no stenosis), <50% stenosis, 50% to 69% stenosis, 70% to 79% stenosis, 80% to 99% stenosis, near-occlusion (string sign), and total occlusion.
