Advances in surgical techniques and graft materials have significantly improved limb salvage rates for patients with severe lower extremity atherosclerotic occlusive disease, reducing amputation rates.

Area of Science:

  • Vascular Surgery
  • Peripheral Artery Disease
  • Limb Salvage

Background:

  • Atherosclerotic occlusive disease of the lower extremity poses a significant threat, especially with severe symptoms like rest pain, ulceration, or tissue necrosis.
  • Past decades have seen major shifts in surgical treatment strategies for lower extremity ischemia, driven by improved understanding of disease patterns.

Purpose of the Study:

  • To review the evolution of surgical approaches and graft materials for lower extremity ischemia.
  • To highlight advancements in diagnostic and surgical techniques contributing to limb salvage.
  • To discuss strategies for managing graft failure and improving outcomes.

Main Methods:

  • Review of historical and current surgical techniques for lower extremity revascularization.

  • Evaluation of autologous vein and synthetic (PTFE) graft utilization.
  • Discussion of diagnostic tools (PVR, ABI, Duplex scanning) and interventions (PTA, surgery) for graft surveillance and management.

    • Main Results:

    • Improved visualization and understanding of segmental and infrapopliteal disease have enhanced limb salvage.
    • Vein grafts are preferred, with strategies to increase availability (ectopic veins, unconventional inflow sites).
    • PTFE grafts serve as an alternative when vein is unavailable, particularly for shorter life expectancies.
    • Aggressive therapeutic approaches, including timely interventions, have led to decreased amputation rates.

    Conclusions:

    • Innovative therapeutic approaches, particularly for infrapopliteal disease, have significantly advanced limb salvage.
    • Enhanced understanding of graft failure and improved surveillance/intervention strategies contribute to better graft patency.
    • The evolution of surgical treatment has demonstrably reduced amputation rates in patients with critical limb ischemia.
