WavelinQ EndoAVF Long Term Patency-A Follow-Up from a Prospective Stud

Area of Science:

• Vascular Surgery
• Minimally Invasive Procedures
• Dialysis Access

Background:

• The WavelinQ EndoAVF system, used since 2018 for minimally invasive arteriovenous fistula (AVF) creation, showed promising short-term results.
• This study evaluates the long-term efficacy and outcomes of the WavelinQ system.

Purpose of the Study:

• To assess the long-term patency and secondary outcomes of the WavelinQ EndoAVF system.
• To compare WavelinQ outcomes with traditional surgical fistula creation.

Main Methods:

• Retrospective cohort study of 32 patients undergoing WavelinQ creation.
• Kaplan-Meier analysis for primary and secondary patency at 6 months, 1 year, and 3 years.
• Tracking of secondary outcomes including flow volume, infection, and steal syndrome.

Main Results:

• Primary patency at 3 years was 7.6%; secondary patency was 46.5%.
• 65.6% of patients required interventions before successful cannulation.
• Low rates of surgical site infection (1) and no instances of steal syndrome were observed.

Conclusions:

• WavelinQ EndoAVF access demonstrates inferior long-term patency compared to surgical fistulas.
• High reintervention rates suggest traditional surgical fistula creation may be superior for long-term dialysis access.
