Endovaskulární léčba arteriovenozních pištělí pro hemodialýzu

Endovascular treatment of arteriovenous fistula for dialysis Aim: Aim of presented retrospective study was to evaluate the primary patency of angioplasty using a drug eluting balloon (DEB) and conventional balloon (PTA) in dysfunctional dialysis fistula. Methods: 58 adult patients treated for fistula dysfunction in the period from 2015 to 2018 were enrolled based on following criteria - matured native fistula with stenosis above 50 % compared to the adjacent healthy vein. Patients with restenosis, swing point, cephalic arch, and central vein stenosis, and multiple distant stenoses were ruled out. Patients were divided into two groups according to received treatment - DEB and PTA. Primary patency of angioplasty was defined as the function of dialysis without the need for clinically driven endovascular or surgical intervention on culprit lesion during follow-up. Secondary, dialysis access patency, 12-month assisted patency, technical, clinical success, complication rate, and mortality among treated groups were evaluated. Results: Primary patency at 6 and 12 months follow up was evaluated in 25 patients in the DEB and 25 patients in the PTA group. Primary lesion and access patency were in DEB vs. PTA: 96 % vs. 76 % (p = 0,1) and 96 % vs. 72 % (p = 0,049) at 6 months, 80 % vs. 56 % (p = 0,13), 80 % vs....
