Polytrimethylene carbonate sutures are a safe, absorbable option for arterial anastomoses, showing less inflammation and promoting vessel wall regeneration compared to nonabsorbable sutures.

Area of Science:

  • Biomaterials Science
  • Vascular Surgery
  • Surgical Sutures

Background:

  • Synthetic absorbable sutures are crucial in vascular surgery.
  • Polytrimethylene carbonate (PTMC) is a synthetic, monofilament, absorbable suture material.
  • Its efficacy in arterial anastomoses requires thorough evaluation.

Purpose of the Study:

  • To assess the suitability of polytrimethylene carbonate sutures for arterial anastomoses.
  • To compare PTMC sutures with nonabsorbable materials (polypropylene, expanded polytetrafluoroethylene).
  • To evaluate histological and arteriographical outcomes.

Main Methods:

  • 108 arterial anastomoses performed in 12 mongrel dogs.
  • Included aortic and femoral patch grafts, and iliofemoral bypasses.

  • Direct intraindividual comparison of PTMC with polypropylene and expanded polytetrafluoroethylene sutures.

    • Main Results:

    • No suture material-related complications like ruptures or aneurysms were observed.
    • PTMC sutures demonstrated reduced inflammation and scar tissue formation versus polypropylene.
    • Complete absorption of PTMC by six months led to vessel wall regeneration, including media layer repair.

    Conclusions:

    • Polytrimethylene carbonate sutures are safe and effective for arterial anastomoses.
    • PTMC promotes better tissue healing and regeneration compared to nonabsorbable sutures.
    • Complete absorption of PTMC facilitates long-term vascular healing.
