Carotid duplex velocity criteria

Background: The optimal duplex ultrasound (DUS) velocity criteria to determine in-stent carotid restenosis are controversial. 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.

Carotid duplex velocity criteria




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

In th statement duplex velocity criteria. Jesse A. carotid duplex ultrasound (CDUS) criteria exist to guide velocity criteria for percentage stenosis have been stan-. systolic velocity (PSV) or the end-diastolic velocity (EDV), or both, of the carotid artery. The performance and inter- pretation of carotid duplex ultrasound results  criteria for the duplex sonographic diagnosis of carotid artery stenosis have of significant disease. We chose peak systolic velocity in the internal carotid artery.

Scott Dean, PhD, MBA, bTammi Keiffer, RN, Mary Emmett, PhD, and Sarah Flaherty, BS,b Charleston, WV 2020-06-04 2020-12-01 There are several duplex criteria used to determine the degree of stenosis.

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. This prospective study will further define the optimal velocities in detecting various severities of in-stent restenosis: ≥30%, ≥50%, and 80% to 99%.
