Efficacy of ultrasound-guided percutaneous transluminal angioplasty for arteriovenous fistula stenosis or occlusion at juxta-anastomosis-a three-year follow-up cohort study

Abstract Objective Arteriovenous fistula (AVF) is the preferred access for hemodialysis. Percutaneous transluminal angioplasty(PTA) has become a choice for AVF stenosis and ultrasound has been used in PTA more frequently. Methods This single-center retrospective cohort study analyzed 129 patients who underwent PTA in the First Affiliated Hospital of Chongqing Medical University from January 2016 to December 2016. Angioplasty was performed using a non-compliant high-pressure balloon. The process was visualized by duplex scan. Our inclusion criteria were as follows: (1)stenoses or occlusions were located at the juxta-anastomosis site:the first 5cm of the vein distal to the anastomosis;(2) stenosis was confirmed with the following conditions:(a)flow ratesare Results Altogether,129 patients with 76 males were analyzed. Moreover,104 have AVFs on left arm,and only one had ulna-basilic AVF, while others had radial-cephalic AVF.The postintervention primary patency rates are better in occlusion cases(P Conclusion For juxta-anastomosis site stenosis or occlusion,PTA can be used to obtain satisfactory results.
