Early PTA in Endo-AVF

Introduction: Evaluate safety and efficacy of early angioplasty (PTA) of the outflow veins during the percutaneous creation of dialysis fistula (Endo-AVF) using the WavelinQ (BD) 4-Fr System. From December 2020 to November 2022, 30 patients underwent Endo-AVF creation with WavelinQ 4-Fr system.

Method(s): PTA of the outflow veins (comitans and perforator) was done during the index procedure to increase the flow within the fistula and reduce the time of maturation and cannulation. Procedures were performed with local-block nerve anesthesia. Technical success was achieved in all patients. In 27/30 patients PTA of the outflow veins was conducted using a 4 mm low-profile balloon inflated at the nominal pressure for 2 minutes. No complications related to PTA were observed.

Result(s): A total of 29/30 reached the maturation of the fistula, as for “the rules of six” criteria, with 600 mL/min flow. First cannulation was done after 60 ± 47 days (range: 11–217 days) in 23 patients.

Conclusion(s): PTA of the outflow veins is safe and effective in shortening the cannulation period in all Endo-AVF procedures with the WavelinQ 4-Fr System.
