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

ABSTRACT

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.
