A salvage technic for extruded arteriovenous shunts

K A Marshall, K Shearlock, R F Edlich

    American Journal of Surgery
    |March 1, 1976
    PubMed
    Summary

    Maintaining arteriovenous shunts and fistulas is crucial during dialysis. Surgical techniques like flap transposition can salvage eroded shunts, preventing their removal and ensuring continued patient treatment.

    Area of Science:

    • Vascular Surgery
    • Nephrology
    • Dialysis Access Management

    Background:

    • Prolonged dialysis necessitates the maintenance of vascular access, such as arteriovenous shunts and fistulas.
    • Erosion of vascular access sites poses a significant risk of complications, including infection and device failure.
    • Preserving existing access is vital for patients undergoing pretransplantation or chronic dialysis.

    Purpose of the Study:

    • To highlight the importance of preserving existing arteriovenous shunts and fistulas.
    • To present surgical techniques for salvaging eroded vascular access.
    • To prevent the premature removal of essential dialysis access.

    Main Methods:

    • Review of surgical techniques for managing eroded vascular access.
    • Description of flap transposition methods, including bipedicle flaps and rotation advancement flaps.
    • Application of these techniques to cover exposed cannulas and salvage shunts.

    Main Results:

    • Surgical transposition of flaps can effectively cover exposed cannulas.
    • These techniques successfully salvage eroded arteriovenous shunts, preventing extrusion.
    • Preservation of vascular access is achievable through these salvage procedures.

    Conclusions:

    • Efforts should be made to maintain and salvage existing arteriovenous shunts and fistulas.
    • Surgical flap techniques offer a viable method for salvaging eroded shunts.
    • Successful salvage prevents device removal and ensures continuity of dialysis treatment.
