The average time between surgery and the ultrasound examination was 38.8 months (range, 3\u201399.2 months). Twenty-nine (23.2%) patients had recurrent carotid artery stenosis after unilateral endarterectomy. Of these, 17 patients were found to have recurrent carotid artery stenosis classified as &lt;50%; 7 patients had recurrent stenosis in the range of 50% and 69%, and 5 patients had &gt;70% diameter-reducing lesions. Plaques associated with recurrent carotid stenosis were significantly less echogenic, more acoustically homogenous, and had a smoother surface contour. Compared with the primary carotid stenosis (nonintervened side), plaques associated with recurrent carotid stenosis were more often hypoechoic (58.6% versus 8.1%), acoustically homogenous (69% versus 44.6%) and smooth-surfaced (93.1% versus 74.3%). Also, the longer the interval between surgery and the carotid sonographic examination, the more similar the ultrasonographic characteristics were between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The different sonographic characteristics of primary carotid stenosis and recurrent stenosis after carotid endarterectomy in the same patients, are associated with different outcomes for the two conditions. There is a current clinical consensus that patients presenting with recurrent symptoms after carotid endarterectomy should be treated, but the best management for asymptomatic patients with recurrent carotid artery stenosis remains uncertain.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/154431671103500101","type":"journal-article","created":{"date-parts":[[2018,3,14]],"date-time":"2018-03-14T12:20:10Z","timestamp":1521030010000},"page":"7-10","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Carotid Artery Restenosis: Ultrasonographic Characteristics"],"prefix":"10.1177","volume":"35","author":[{"given":"Miguel","family":"Maia","sequence":"first","affiliation":[{"name":"Servico de Angiologia e Cirurgia Vascular, Rua Conceicao Fernandes, Vila Nova de Gaia, Portugal."}]},{"given":"Joana","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Servico de Angiologia e Cirurgia Vascular, Rua Conceicao Fernandes, Vila Nova de Gaia, Portugal."}]},{"given":"Sandrina","family":"Braga","sequence":"additional","affiliation":[{"name":"Servico de Angiologia e Cirurgia Vascular, Rua Conceicao Fernandes, Vila Nova de Gaia, Portugal."}]},{"given":"Jo\u00e3o","family":"Vasconcelos","sequence":"additional","affiliation":[{"name":"Servico de Angiologia e Cirurgia Vascular, Rua Conceicao Fernandes, Vila Nova de Gaia, Portugal."}]},{"given":"Pedro","family":"Brand\u00e3o","sequence":"additional","affiliation":[{"name":"Servico de Angiologia e Cirurgia Vascular, Rua Conceicao Fernandes, Vila Nova de Gaia, Portugal."}]},{"given":"Guedes","family":"Vaz","sequence":"additional","affiliation":[{"name":"Servico de Angiologia e Cirurgia Vascular, Rua Conceicao Fernandes, Vila Nova de Gaia, Portugal."}]}],"member":"179","published-online":{"date-parts":[[2018,3,14]]},"reference":[{"key":"bibr1-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1111\/j.1742-1241.2005.00775.x"},{"key":"bibr2-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-199011000-00011"},{"key":"bibr3-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9610(88)80362-3"},{"key":"bibr4-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.29.1.244"},{"key":"bibr5-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(96)70095-2"},{"key":"bibr6-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.01.065"},{"key":"bibr7-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2292030516"},{"key":"bibr8-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800840906"},{"key":"bibr9-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(89)90010-4"},{"key":"bibr10-154431671103500101","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(92)90057-F"}],"container-title":["Journal for Vascular Ultrasound"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/154431671103500101","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/154431671103500101","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/154431671103500101","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T06:56:54Z","timestamp":1777705014000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/154431671103500101"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,3]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2011,3]]}},"alternative-id":["10.1177\/154431671103500101"],"URL":"https:\/\/doi.org\/10.1177\/154431671103500101","relation":{},"ISSN":["1544-3167","1544-3175"],"issn-type":[{"value":"1544-3167","type":"print"},{"value":"1544-3175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,3]]}}}
