Percutaneous transluminal balloon angioplasty in XXXX of native hemodialysis @entity2548 : technical success and analysis of factors affecting postprocedural fistula patency.

PURPOSE: We aimed to determine the predictors of technical success and patency after percutaneous transluminal angioplasty (PTA) of de novo dysfunctional hemodialysis @entity2548 ( @entity2548 ). METHODS: We performed a retrospective analysis of first time PTA in 228 @entity1 (129 @entity1 , 99 @entity1 ; mean age, 56.8  14.6 years). Anatomical (location, length, grade, and number of stenoses) and clinical variables (sex, age, prior @entity2548 , @entity6 , @entity2548 age, side, and location) were reviewed. RESULTS: A total of 330 stenoses were found in 228 @entity1 . PTA was technically successful in 96.3% of the stenoses (n=319). Clinical success was achieved in 97.2% (n=321). Early dysfunction (within six months) was positively correlated with @entity1 age (P < 0.001) and @entity6 (P < 0.005). Older age (P < 0.001) and @entity6 (P = 0.002) were associated with a lower primary patency rate. @entity1 age (P %lt; 0.001), presence of @entity6 (P = 0.023), length of @entity850 (P = 0.003), early recurrence (P = 0.003) and presence of residual @entity850 (P = 0.014) were associated with a lower secondary patency rate. CONCLUSION: Patency of dysfunctional hemodialysis fistulas can be maintained safely with continuous follow-up and repeated interventions without shortening the venous segment by surgical revision. Percutaneous approach to hemodialysis access @entity850 is an alternative to the conventional surgical approach and PTA is an effective treatment method for dysfunctional @entity2548 .
