Abstract Objective: To report the technical success and long-term clinical outcomes of arteriovenous fistula (AVF) stenosis after percutaneous transluminal balloon angioplasty (PTA). Methods: A total of 30 patients with stenosis of AVF were enrolled. There were 16 men and 14 women, and the median age was 64.8±13.2 years. Mean time between fistula creation and intervention was 16.5±13.8 months. The mean duration of hemodialysis time was 31.5±30.2 months. They were examined by digital subtraction angiography (DSA) when they underwent PTA. After the treatment of PTA, all of the patients were examined by 64-multislice spiral computed tomography angiography every 3 months. Results: The technical success rate was 90.0% in the hemodialysis patients (17 native AVFs and 10 arteriovenous grafts). Primary patency at first, second, third, fourth and fifth three months was 100%, 91.3%, 79.5%, 72.6% and 62.2% respectively. Univariate analysis indicated that there was no significant correlation between the clinical factors (including age, diabetes mellitus, location, length, grade, and number of stenosis) and primary patency (P>0.05). Conclusion: PTA is an effective treatment method for arteriovenous stenosis, which has high rates of technical success and less complication.
