Materials and Methods: A single-center retrospective study was conducted of 42 consecutive patients (mean age 66.7 years, range 40\u201384; 26 men) who had a failing AVF due to juxta-anastomotic stenosis treated with the interwoven Supera stent between February 2014 and February 2018. A third of the patients had previous juxta-anastomotic intervention (either balloon angioplasty or open surgical revision). Results: The stent was inserted successfully in all patients. Overall mean follow-up was 12.2\u00b18.2 months (range 3.8\u201338.3). Juxta-anastomotic segment primary patency estimates at 6 and 12 months were 92.5% and 59.8%, respectively, with assisted primary patency rates of 97.5% and 92.9%. Reintervention (elective drug-coated balloon angioplasty) occurred at a rate of 0.31 procedures\/year. Two AVFs thrombosed during the 1-year follow-up and were revascularized using balloon angioplasty. Ultrasound measurements of brachial artery flow rates increased significantly from 543.5\u00b196.72 mL\/min (range 430\u2013644) before intervention to 919.2\u00b1355.9 mL\/min (range 200\u20131600) after intervention (p=0.047). Arterial pressures on hemodialysis improved from \u2212142.3\u00b124.9 mm Hg (range \u2212100 to \u2212180) to \u2212123.4\u00b121.9 mm Hg (range \u2212100 to \u2212184; p=0.051). No AVFs were lost or abandoned during the follow-up period. Conclusion: The interwoven Supera stent is a promising treatment for failing AVFs with juxta-anastomotic stenosis. Encouraging 1-year primary and assisted primary patency was demonstrated, with a low reintervention rate. This treatment facilitates long-term maintenance of AVF vascular accesses.<\/jats:p>","DOI":"10.1177\/1526602819842851","type":"journal-article","created":{"date-parts":[[2019,4,11]],"date-time":"2019-04-11T07:27:24Z","timestamp":1554967644000},"page":"394-401","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":21,"title":["Interwoven
