This phenomenon may often mislead the interventionist into performing unnecessary and potentially harmful procedures in a bid to treat the \u2018stenotic\u2019 lesion. The resolution of \u2018stenosis\u2019 on withdrawal of the guidewire clinches the diagnosis. While well described in coronary vessels, the occurrence of this phenomenon in arteriovenous fistula or graft has not been reported. We describe a case of accordion effect observed during endovascular intervention for arteriovenous graft salvage.<\/jats:p>","DOI":"10.1177\/1129729820927248","type":"journal-article","created":{"date-parts":[[2020,6,10]],"date-time":"2020-06-10T05:46:28Z","timestamp":1591767988000},"page":"670-672","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Accordion effect: A red herring during percutaneous angioplasty of arteriovenous dialysis access"],"prefix":"10.1177","volume":"22","author":[{"given":"Indu Ramachandra","family":"Rao","sequence":"first","affiliation":[{"name":"Department of Nephrology, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4332-3665","authenticated-orcid":false,"given":"Ganesh","family":"Paramasivam","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tom","family":"Devasia","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Attur Ravindra","family":"Prabhu","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shankar Prasad","family":"Nagaraju","sequence":"additional","affiliation":[{"name":"Department of Nephrology, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,6,10]]},"reference":[{"key":"bibr1-1129729820927248","doi-asserted-by":"publisher","DOI":"10.1186\/1757-1626-1-138"},{"key":"bibr2-1129729820927248","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810340209"},{"key":"bibr3-1129729820927248","doi-asserted-by":"publisher","DOI":"10.4103\/0028-3886.105209"},{"key":"bibr4-1129729820927248","doi-asserted-by":"publisher","DOI":"10.1177\/152660280100800116"},{"key":"bibr5-1129729820927248","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-007-0222-4"}],"container-title":["The Journal of Vascular Access"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1129729820927248","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1129729820927248","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1129729820927248","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T03:16:08Z","timestamp":1777691768000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1129729820927248"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,6,10]]},"references-count":5,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2021,7]]}},"alternative-id":["10.1177\/1129729820927248"],"URL":"https:\/\/doi.org\/10.1177\/1129729820927248","relation":{},"ISSN":["1129-7298","1724-6032"],"issn-type":[{"value":"1129-7298","type":"print"},{"value":"1724-6032","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,6,10]]}}}
