Summary

Axillary bridge fistulas provide durable hemodialysis access when arm sites are exhausted. This study found comparable complication rates to conventional methods, making them a viable secondary access option.

Area of Science:

  • Vascular Surgery
  • Nephrology
  • Dialysis Access

Background:

  • Patients undergoing long-term hemodialysis often exhaust conventional arm access sites.
  • Alternative access strategies are crucial for maintaining adequate dialysis treatment.
  • Axillary polytetrafluoroethylene (PTFE) bridge fistulas represent a potential secondary access option.

Purpose of the Study:

  • To evaluate the largest reported experience with axillary artery-to-vein PTFE bridge fistulas for hemodialysis.
  • To determine the complication incidence and durability of this secondary access strategy.
  • To clarify the role of axillary bridge fistulas in the dialysis access algorithm.

Main Methods:

  • Retrospective review of a single center's experience over 5 years.
  • Analysis of 26 axillary PTFE bridge fistulas placed in 24 patients.
  • Assessment of patency, infection, thrombosis, and other complications.

Main Results:

  • Twenty-six axillary grafts were placed, with 25 used for dialysis.
  • Patients had a mean of 77 months of prior dialysis and 9.4 previous access procedures.
  • Three-year life-table patency rate was 60%; infection and thrombosis rates were comparable to arm fistulas.
  • No instances of vascular steal or neurologic injury were observed.

Conclusions:

  • Axillary artery-to-vein PTFE bridge fistulas are an excellent and durable secondary access option.
  • This procedure is recommended after conventional arm sites have been exhausted.
  • Axillary bridge fistulas offer a reliable solution for patients with limited access options.
