The aim of this study was to assess the mid-term patency and complication rates of angioplasty procedures performed in a single center for treatment of stenosis compromising vascular accesses. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> A prospective database of vascular accesses performed in 2006\u20132010 was investigated. The endovascular approach was applied following a standardized protocol by a dedicated team. A total of 531 consecutive procedures were reviewed (326 men; mean age 70.94 years). Patency rates were estimated using the Kaplan-Meier method. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> There were 199 procedures for failing access: 135 were surgical and 64 angioplasties performed for anastomosis (n=27), venous (n=45) or arterial (n=7) stenosis. Immediate technical success of endovascular procedures was 95.3%(61\/64); complication rate was 6.3% (4\/64). Primary patency rates were 55% at six months, 49% at 12 months, and 21% at 24 months. In the concurrent group of 135 open procedures, primary patency rates were 80% at six months and 67% at 12 months (P=.002); nevertheless, at 24 months, patency was as low as 49%. Cost estimates for angioplasty revealed additional fees ranging from 411.34 to 446.34 Euro with respect to open surgical procedures. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> Most dysfunctional vascular accesses can be successfully and safely treated by the endovascular route. In spite of poor mid-term durability, the angioplasty balloon might be considered as a bridge, effective, and repeatable solution with reasonable costs to prolong access survival avoiding additional surgery. The failure rate in the mid-term for dysfunctional vascular access may also be high after surgical reintervention. <\/jats:p><\/jats:sec>","DOI":"10.5301\/jva.5000060","type":"journal-article","created":{"date-parts":[[2012,2,22]],"date-time":"2012-02-22T14:37:58Z","timestamp":1329921478000},"page":"381-387","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Percutaneous Approach in the Maintenance and Salvage of Dysfunctional Autologous Vascular Access for Dialysis"],"prefix":"10.1177","volume":"13","author":[{"given":"Paola","family":"De Rango","sequence":"first","affiliation":[{"name":"Unit of Vascular and Endovascular Surgery, Hospital S.
