Aim: dysfunctional arteriovenous (av) access remains a significant cause of morbidity and hospital admission for patients with end stage renal failure on haemodialysis.This study was performed to evaluate the impact of paclitaxel-coated balloon (pcb) on the patency of av access with recurrent stenoses.Within this retrospective study the impact adrmiral drug-coated balloon was used.Methods: we retrospectively studied haemodialysis patients who presented to our centre with recurrent av access dysfunction and compared intervention-free patency using plain balloon versus pcb.Results: a total of 147 patients were followed up longitudinally.Intervention-free patency was better following pcb compared to previous intervention using plain balloons (6.4 5.8 versus 4.0 3.7, p <(><<)> 0.01).The 3- and 6-month patency rates after pcb were significantly better compared to standard plain angioplasty balloon: 69.4% versus 52.4%, p <(><<)> 0.01 and 42.9% versus 15.6%, p <(><<)> 0.01 respectively.Kaplan¿meier survival analysis of circuit patency demonstrated the superiority of pcb over plain balloon angioplasty in both arteriovenous fistula and arteriovenous graft (p <(><<)> 0.01 and p = 0.01 respectively) although the patency of arteriovenous fistula remained significantly better than arteriovenous graft following interventions with pcb (p <(><<)> 0.01).Age of av access and the number of previous interventions were found to be significant predictors of patency following pcb intervention.Conclusion: arteriovenous access intervention with pcb was shown to be superior compared to plain balloon in the treatment of both nonthrombosed and thrombosed av accesses in our multi-ethnic population.
