The ability to predict which B-C AVFs are at risk for recurrent stenosis post-PTA would allow closer monitoring of patients, and possibly result in surgical intervention rather than repeat PTA. The purpose of this study was to identify predictive factors of primary patency after PTA in B-C AVFs.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods:<\/jats:title>\n                  <jats:p>Patients diagnosed with B-C AVF primary stenosis and treated by PTA between November 2013 and March 2018 were included in the study.

The mean B-C AVF age was 16.34 \u00b1 12.93 months (range, 2\u201384 months), and the median primary patency time was 7.79 \u00b1 0.48 months. Cox proportional hazard regression analysis revealed stenosis location at the inflow artery [hazard ratio (HR)=3.83, 95% confidence interval (CI): 1.46\u201310.09] or anastomosis (HR = 1.90, 95%\u2009CI: 1.09\u20133.32), dilation &amp;gt;2 times during PTA (HR = 2.30, 95%\u2009CI: 1.22\u20134.34), and residual stenosis &amp;gt;30% (HR = 2.42, 95%\u2009CI: 1.26\u20134.63) were significantly associated with decreased patency.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>In conclusion, the primary patency rate of PTA for B-C AVF dysfunction is reduced by dilation &amp;gt;2 times, residual stenosis &amp;gt;30%, and stenosis located at the inflow artery or anastomosis.
