ICA, common carotid artery (CCA), and ECA peak systolic velocities (PSVs) were recorded. ECA/CCA PSV ratio was calculated. [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 … Optimal carotid duplex velocity criteria for deﬁning the severity of carotid in-stent restenosis Ali F.

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 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.

This prospective study revisits DUS criteria for determining the rate of in-stent restenosis. In analyzing a subset of 12 patients (pilot study) who had both completion carotid angiography and DUS within 30 days, 10 patients with normal post-stenting carotid angiography (< 30% residual stenosis) had peak systolic velocities (PSVs) of the stented internal The optimal DUS velocity criteria for in-stent restenosis of >or=30%, >or=50%, and >or=80% were the PSVs of 154, 224, and 325 cm/s, respectively. Optimal carotid duplex velocity criteria for defining the severity of carotid in-stent restenosis When we initially applied our Intersocietal Commission for the Accreditation of Vascular Laboratories-accredited vascular laboratory duplex velocity cutoff PSV of ≥ 140 cm/s criterion, which was 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 Optimal carotid duplex velocity criteria for defining the severity of carotid in-stent restenosis Presented at the Society for Clinical Vascular Surgery Annual Meeting, Las Vegas, Nev, Mar 5-8, 2008.

Sensitivities and specificities were highest when peak ICA velocity was used as one of several criteria in quan tifying the degree of Development of Duplex Ultrasound Criteria for External Carotid Artery Stenosis: Importance of Assessing Both Peak Systolic Velocity and Presence of Color Aliasing. Matthew Kronick MD, Atish Chopra MD, Enjae Jung MD, Cherrie Abraham MD, Timothy Liem MD, Erica Mitchell MD, Gregory Landry MD, Gregory Moneta, MD. 2021-04-01 · BACKGROUND: Validation of carotid duplex ultrasound velocity criteria (CDUS VC) to grade the severity of extracranial carotid artery stenosis has traditionally been based on conventional angiography measurements. In the last decade, computed tomographic angiography (CTA) has largely replaced Carotid 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 acceptable method for revascularization in circumstances where CEA yields suboptimal results. While the final role of CAS in carotid revascularization is Optimal criteria for the duplex sonographic diagnosis of carotid artery stenosis have not yet been defined. We studied 205 vessels in 105 patients with both duplex sonography and angiography.

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.
