Laser Doppler Flowmetry (LDF) can help monitor free flap blood flow, but interpreting its continuous recordings is crucial for reliable results in microvascular surgery. Careful analysis of LDF patterns is essential for detecting complications like thrombosis.

Area of Science:

  • Plastic Surgery
  • Microsurgery
  • Biomedical Engineering

Background:

  • Microvascular free flap transfer is increasingly safe, but thrombosis remains a complication.
  • Objective blood flow monitoring is needed to detect issues promptly and avoid re-operation delays.
  • Laser Doppler Flowmetry (LDF) is a technique used for this purpose, though its reliability is debated.

Purpose of the Study:

  • To evaluate the reliability of Laser Doppler Flowmetry (LDF) in monitoring latissimus dorsi free flaps.
  • To emphasize the importance of interpreting continuous LDF recordings for accurate blood flow assessment.

Main Methods:

  • Continuous Laser Doppler Flowmetry (LDF) monitoring was performed on six latissimus dorsi free flaps.
  • Analysis focused on LDF values, recording patterns, and correlation with flap outcomes.

  • Specific attention was given to fluctuations and absolute values in relation to physiological variations and complications.

    • Main Results:

    • Uneventful flaps showed physiological fluctuations in LDF values.
    • One flap with venous thrombosis had a stable, non-fluctuating LDF despite an initially acceptable value.
    • Probe positioning significantly affected LDF readings in one case.
    • A sudden LDF drop correlated with venous obstruction, confirmed surgically.

    Conclusions:

    • Interpreting the pattern of continuous LDF recordings, not just absolute values, is critical for reliable free flap monitoring.
    • LDF can detect microvascular thrombosis, but requires careful analysis of signal fluctuations and changes.
    • Further refinement in LDF interpretation protocols may enhance its utility in preventing flap failure.
