Area of Science:

  • Vascular Surgery
  • Nephrology
  • Dialysis Access

Background:

  • Arteriovenous fistulas (AVFs) are crucial for hemodialysis access.
  • Traditional radiocephalic fistulas can have limitations in patency and complications.
  • Alternative AVF creation sites are being explored to improve outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of creating AV fistulas at the anatomical snuff-box.
  • To compare the outcomes of snuff-box fistulas with the standard Brescia-Cimino fistula.
  • To assess the patency rates and complication profile of this novel approach.

Main Methods:

  • A total of 192 arteriovenous fistulas were surgically created at the anatomical snuff-box.
  • Patency was assessed at one month post-operatively.

  • Complications and the need for revision were recorded.

    • Main Results:

    • A high primary patency rate of 94.8% was achieved at one month for snuff-box fistulas.
    • Compared to Brescia-Cimino fistulas, the snuff-box approach showed fewer wound complications.
    • This method preserves more proximal access sites for future procedures.

    Conclusions:

    • The anatomical snuff-box arteriovenous fistula is a safe and effective option for hemodialysis access.
    • It offers advantages including ease of creation, superior patency, and reduced complications.
    • This technique provides a valuable alternative, preserving future vascular access options.
