    Summary

    A novel venous interposition graft technique using sleeve anastomosis and fibrin glue significantly reduces operative time and improves vascular healing. This method achieved a 97% patency rate in animal studies and showed good results in a clinical finger amputation case.

    Area of Science:

    • Vascular Surgery
    • Microsurgery
    • Regenerative Medicine

    Background:

    • Traditional venous interposition grafts often require complex suturing techniques, increasing operative time and potential for complications like leakage.
    • Minimizing suture lines and ensuring graft-host anastomosis integrity are critical for successful vascular reconstruction.

    Observation:

    • A new technique applies the sleeve anastomosis principle proximally and fibrin glue to both suture sites for venous interposition grafts.
    • This approach aims to reduce suture requirements and enhance hemostasis, thereby simplifying the procedure and improving healing.

    Findings:

    • The modified technique led to a reduction in the number of stitches, decreasing operative time and promoting good vascular healing.
    • Animal experiments demonstrated a high graft patency rate of 97%.

  • A clinical application in a finger amputation case showed successful recirculation on angiography at 6 weeks postoperatively.
  • Implications:

    • This simplified venous grafting technique offers a promising alternative for vascular reconstruction, potentially reducing surgical complexity and improving patient outcomes.
    • The high patency rates suggest its efficacy in challenging microsurgical scenarios, such as digital replantation or revascularization.
    • Further clinical studies are warranted to validate its long-term effectiveness and broader applicability in reconstructive surgery.
