J Vasc Surg. 1994; 19: 818–827;discussion 827–828. Crossref Medline Google Scholar In a study of 100 patients with 184 internal carotid arteries who had duplex scans and arteriograms interpreted by the NASCET method, an internal carotid artery to common carotid artery PSV ratio of ≥4.0 provided the best sensitivity (91%), specificity (87%), and overall accuracy (88%) for detection of a 70% to 99% NASCET stenosis .

AbuRahma and associates concluded that different carotid duplex velocity criteria should be used to detect restenosis after CEA when a patch closure has been performed. 26. Although it may be true that intimal hyperplasia causing early restenosis in patched carotid arteries is less compliant and, The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Various duplex criteria have been used to predict hemodynamically significant carotid artery stenosis. Clinicians have relied on published institutional experience for carotid duplex ultrasound 2010-09-07 2011-02-01 2017-04-01 Carotid duplex velocity criteria revisited for the diagnosis of carotid in-stent restenosis. Ali F AbuRahma, Damian Maxwell, Kris Eads, Sarah K Flaherty, Tabitha Stutler Vascular 2007, 15 (3): 119-25 Ultrasound criteria for severe in-stent restenosis following carotid artery stenting. Background—Duplex ultrasonography criteria for assessing the severity of carotid artery (CA) in-stent restenosis are not well established. Methods and Results—We analyzed 39 patients (40 CAs) who underwent CA stenting with baseline and 6-month follow-up carotid duplex ultrasonography and intravascular ultrasound.
