Overall, the incidence of thrombosis\/occlusion (per patient-year) was 0.12 for fistulae and 0.9 for grafts. The anatomical success rate for EVS was 94% for fistulae and 92% for grafts. Primary patency rates for fistulae at 1, 6, 12, 24 and 36 months were 82, 64, 44, 34 and 26%, respectively, whereas secondary patency rates were 88, 84, 74, 69 and 61%, respectively. Primary patency rates for grafts at 1, 6 and 12 months were 50, 14 and 8%. The overall rate of complications was 6% with no incidence of symptomatic pulmonary embolism. In a Cox regression model, upper-arm location of fistula (HR 1.9, p = 0.04, n = 144) was associated with lower primary patency, whereas the presence of thrombosis was associated lower primary (HR 1.9, p = 0.004, n = 144) and secondary patency (HR 3.7, p &lt; 0.001, n = 144). Aspirin therapy was associated with longer primary patency (HR 0.6, p = 0.02, n = 144) and secondary patency (HR 0.58, p = 0.08, n = 144). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; EVS is effective but longer-term outcomes are poor. Presence of thrombosis portends poor fistula survival and strategies for prevention need attention. Balloon maceration, our preferred declotting technique, is safe and the most cost-effective method. Aspirin therapy for patients presenting with failure of fistulae deserves further investigation.<\/jats:p>","DOI":"10.1159\/000375500","type":"journal-article","created":{"date-parts":[[2015,3,9]],"date-time":"2015-03-09T11:52:06Z","timestamp":1425901926000},"page":"241-246","source":"Crossref","is-referenced-by-count":17,"title":["Acute Arteriovenous Access Failure: Long-Term Outcomes of Endovascular Salvage and Assessment of Co-Variates Affecting Patency"],"prefix":"10.1159","volume":"129","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5040-2310","authenticated-orcid":false,"given":"Milind D.","family":"Nikam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Ritchie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anu","family":"Jayanti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ondina A.","family":"Bernstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonard","family":"Ebah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Brenchley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alastair","family":"Hutchison","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas","family":"Chalmers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandip","family":"Mitra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2015,3,6]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.2215\/CJN.02950707"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/15.12.2029"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1097\/01.RVI.0000182157.48697.F5"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(99)70071-0"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.06.058"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22913"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-008-9478-2"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(95)71164-2"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/S1051-0443(07)61355-4"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.200.1.8657906"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S0272-6386(99)70344-6"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525-139X.2010.00780.x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2006.04.040"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfm021"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1159\/000328071"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2007.11.025"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1038\/ki.2011.337"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1111\/sdi.12187"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1001\/jama.299.18.2164"}],"container-title":["Nephron"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/375500","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/375500","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:43:15Z","timestamp":1745430195000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000375500"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":19,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2015,4,1]]},"published-print":{"date-parts":[[2015,5,5]]}},"URL":"https:\/\/doi.org\/10.1159\/000375500","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.5127679","asserted-by":"subject"}]},"ISSN":["1660-8151","2235-3186"],"issn-type":[{"value":"1660-8151","type":"print"},{"value":"2235-3186","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
