Summary

Diabetic foot tissue defects require tailored microsurgical flap transfers based on underlying causes like neuropathy or ischemia. This study defines indications for three distinct flap techniques to improve healing outcomes.

Area of Science:

  • Vascular Surgery
  • Diabetic Foot Management
  • Microsurgery

Background:

  • Diabetic foot complications stem from complex pathogenetic mechanisms, including diabetic neuropathies, ischemia, and microangiopathies, complicating wound healing.
  • Serious tissue defects in diabetic foot patients present significant treatment challenges due to multifactorial influences on healing processes.

Purpose of the Study:

  • To analyze pathogenetic factors influencing diabetic foot wound healing.
  • To define indications for three distinct microsurgical flap transfer techniques for treating severe diabetic foot tissue defects.

Main Methods:

  • A three-year prospective study involving microsurgical flap transfers.
  • Classification of flap techniques based on defect characteristics: direct vascular anastomosis, politeopedal bypass, or "nourishing" flap with venous graft.

  • Analysis of patient outcomes following different flap procedures.

    • Main Results:

    • Thirteen patients underwent microsurgical free muscle flap operations in the first year.
    • Ten flaps were directly sutured at the defect site, and three were "nourishing" flaps.
    • Twelve out of thirteen flaps healed successfully; one patient experienced a fatal myocardial infarction post-surgery.

    Conclusions:

    • Microsurgical flap transfer is a viable option for treating complex diabetic foot tissue defects.
    • Tailoring the microsurgical approach based on the predominant pathogenetic mechanism (neuropathic vs. ischemic) is crucial for successful outcomes.
    • Further investigation is warranted to refine indications and optimize outcomes for different flap techniques in diabetic foot reconstruction.
