Two hundred CEA patients with 195 pairs of imaging (duplex ultrasound versus computed tomography angiography [CTA]\/carotid arteriography) were analyzed. Peak systolic velocities (PSVs), end diastolic velocity (EDV) and internal carotid artery\/common carotid artery (ICA\/CCA) ratios were correlated to angiography. Receiver operator characteristic (ROC) curves determined optimal velocity criteria in detecting \u226550% and \u226580% restenosis. The mean PSVs for \u226550% and \u226580% restenosis were 248 and 404 c\/s, respectively ( P &lt; 0.001). A PSV of \u2265213 c\/s was optimal for \u226550% restenosis with sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and overall accuracy (OA) of 99%, 100%, 100%, 98% and 99%, respectively. An ICA PSV of 274 c\/s was optimal for \u226580% restenosis with sensitivity, specificity, PPV, NPV and OA of 100%, 91%, 99%, 100% and 99%, respectively. ROC analysis showed that PSVs were significantly better than EDVs and ICA\/CCA ratios in detecting \u226550% restenosis. Standard duplex velocity criteria should be revised after CEA using patching. Specific carotid duplex velocities can be used to detect \u226550% and \u226580% restenosis after CEA with patch closure prior to carotid intervention\/CAS. <\/jats:p>","DOI":"10.1258\/vasc.2010.oa0245","type":"journal-article","created":{"date-parts":[[2011,2,15]],"date-time":"2011-02-15T23:25:41Z","timestamp":1297812341000},"page":"15-20","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Duplex criteria for determining \u226550% and \u226580% internal carotid artery stenosis following carotid endarterectomy with patch angioplasty"],"prefix":"10.1177","volume":"19","author":[{"given":"Ali F","family":"AbuRahma","sequence":"first","affiliation":[{"name":"Vascular Center of Excellence, Robert C Byrd Health Sciences Center, West Virginia University, 3110 MacCorkle Ave., SE, Charleston, WV 25304, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,2,1]]},"reference":[{"key":"bibr-VASC-02-10-OA-0245C1","doi-asserted-by":"publisher","DOI":"10.1007\/s100169900166"},{"key":"bibr-VASC-02-10-OA-0245C2","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(94)70006-0"},{"key":"bibr-VASC-02-10-OA-0245C3","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(93)90019-I"},{"key":"bibr-VASC-02-10-OA-0245C4","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(95)70228-8"},{"key":"bibr-VASC-02-10-OA-0245C5","first-page":"10","volume":"8","author":"Hirschl M","year":"1989","journal-title":"Int Angiol"},{"key":"bibr-VASC-02-10-OA-0245C6","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.27.11.2075"},{"key":"bibr-VASC-02-10-OA-0245C7","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(99)70376-9"},{"key":"bibr-VASC-02-10-OA-0245C8","doi-asserted-by":"publisher","DOI":"10.1177\/152660280000700501"},{"key":"bibr-VASC-02-10-OA-0245C9","doi-asserted-by":"publisher","DOI":"10.1067\/mva.2001.118591"},{"key":"bibr-VASC-02-10-OA-0245C10","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2006.09.020"},{"key":"bibr-VASC-02-10-OA-0245C11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.09.013"},{"key":"bibr-VASC-02-10-OA-0245C12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2008.01.057"},{"key":"bibr-VASC-02-10-OA-0245C13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2005.02.044"},{"key":"bibr-VASC-02-10-OA-0245C14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2008.04.004"},{"key":"bibr-VASC-02-10-OA-0245C15","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199108153250701"},{"key":"bibr-VASC-02-10-OA-0245C16","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(98)70165-X"},{"key":"bibr-VASC-02-10-OA-0245C17","doi-asserted-by":"publisher","DOI":"10.1177\/000313480306901005"}],"container-title":["Vascular"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1258\/vasc.2010.oa0245","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1258\/vasc.2010.oa0245","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1258\/vasc.2010.oa0245","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,27]],"date-time":"2025-02-27T19:29:14Z","timestamp":1740684554000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1258\/vasc.2010.oa0245"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,2]]},"references-count":17,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2011,2]]}},"alternative-id":["10.1258\/vasc.2010.oa0245"],"URL":"https:\/\/doi.org\/10.1258\/vasc.2010.oa0245","relation":{},"ISSN":["1708-5381","1708-539X"],"issn-type":[{"value":"1708-5381","type":"print"},{"value":"1708-539X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,2]]}}}
