Effectiveness and Influencing Factors of Percutaneous Transluminal Angioplasty for Stenosis of Transposed Brachiobasilic Arteriovenous Fistula

Purpose To evaluate effectiveness of percutaneous transluminal angioplasty (PTA) for transposed brachiobasilic arteriovenous fistula (tBBAVF), and to analyze the factors influencing patency after PTA. Materials and Methods In 101 patients who underwent operation for tBBAVF from January 2006 to February 2008, we identified 42 patients undergoing PTA. We conducted a retrospective analysis of sequential PTAs in these patients from 2006 to 2017. Results A total of 100 PTAs were performed. The technical success rate was 93% and the clinical success was 100%. Only ruptures occurred in 12% as minor complications. Primary patency rate was 61%, 29%, 7%, and secondary patency was 91%, 82%, 59% at 6, 12, and 24 months, respectively. Primary patency rate was lower in tBBAVF with rupture (p = 0.024). Secondary patency rate was significantly lower in the diabetes (p = 0.002). Conclusion Repetitive PTAs in tBBAVF are acceptable due to excellent secondary patency. Primary patency of tBBAVF is low in patients with rupture. Diabetes itself has a significant effect on secondary patency.
