¹Kalp ve Damar Cerrahisi Kliniği, Özel Erdem Hastanesi, İstanbul DOI : 10.9739/uvcd.2017-56042 Objective: Percutaneous transluminal angioplasty (PTA) is recommended as first-line treatment in AV fistula failures. Material and Methods: We retrospectively reviewed 72 end stage renal failure patients treated in our clinic for AV fistula insufficiency between January 2014 and June 2016. Results: The mean age of the patients studied was 64.88±11.56. Thirty-three (45.8%) cases were male. The postoperative one year patency rate was 77.8%, seconder patency rate was 83.4%. Conclusion: We think that endovascular treatment of AV fistula failures can be performed safely with acceptable patency and as first-line treatment.
