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 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.

The test allows stratification of the degree of carotid artery stenosis on the basis of greyscale 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. [PSV = peak systolic velocity; EDV = end-diastolic velocity; ICA = internal carotid artery; CCA = common carotid artery] normal.

23 Peak systolic velocity greater than 125 cm/s but less than the criteria for critical stenosis constitutes 50% to 69% stenosis. Though also imperfect, we recommend requiring criteria in addition to ≥230 cm/s peak-systolic velocity such as end-diastolic velocity ≥100 cm/s or internal carotid artery-to-common carotid artery ratio ≥4.0 or computed tomography or magnetic resonance angiogram showing ≥70% stenosis. We have always used velocity thresholds to classify the severity of internal carotid stenosis Velocity criteria have traditionally been validated by comparison with the “gold standard” of arteriography What is the relationship between velocity and % arteriographic stenosis? Velocity vs. Stenosis CAROTID DUPLEX CRITERIA Duplex Ultrasound Velocity Criteria in Carotid Artery Stenting Patients. Incidence of in-stent restenosis after carotid artery stenting (CAS).

[PSV = peak systolic velocity; EDV = end-diastolic velocity; ICA = internal carotid artery; CCA = common carotid artery] normal. ICA PSV is <125 cm/sec and no plaque or intimal thickening is visible sonographically; additional criteria include ICA/CCA PSV ratio <2.0 …

The use of receiver operating characteristic curves allows the individualization of duplex criteria to the clinical situation. 2008-09-01 · The optimal duplex ultrasound (DUS) velocity criteria to determine in-stent carotid restenosis are controversial. We previously reported the optimal DUS velocities for ≥30% in-stent restenosis.

Incidence of in-stent restenosis after carotid artery stenting (CAS). ( a) Kaplan-Meier cumulative event rates for clinically significant ISR ≥ 80% after CAS. ( b) Kaplan-Meier cumulative event rates for ISR ≥ 60% after CAS. Se hela listan på ahajournals.org 2010-09-07 · Systolic velocity > 1.25 m/s is consistent with an angiographic stenosis > 50% diameter reduction (DR). Both the PSV = 2.69 m/s and the EAV = 1.78 m/s exceed the criterion.
