    Determining the optimal amputation level for below-knee amputees with vascular disease is crucial for healing. Measuring skin capillary blood flow offers the most accurate, objective method for predicting wound healing potential.

    Area of Science:

    • Vascular Surgery
    • Wound Healing
    • Amputation Level Determination

    Background:

    • Below-knee amputations offer superior rehabilitative potential compared to above-knee amputations.
    • In end-stage occlusive vascular disease, stump healing is the primary limitation for distal amputation.
    • Current clinical judgment for determining amputation level is subjective and unreliable.

    Purpose of the Study:

    • To identify a reliable and objective method for determining the optimal amputation level.
    • To evaluate various objective parameters for predicting wound healing potential in amputations.

    Main Methods:

    • Review of studies evaluating objective parameters for amputation level determination.
    • Comparison of measurements including local blood flow, pressure, blood volume, and skin temperature.

  • Focus on the accuracy of skin capillary blood flow measurement.

    • Main Results:

    • Clinical judgment for amputation level is subjective.
    • Several objective methods have been proposed, including blood flow and pressure measurements.
    • Measurement of skin capillary blood flow emerged as the most accurate predictor of wound healing.

    Conclusions:

    • Skin capillary blood flow measurement is the most accurate objective parameter for predicting amputation stump healing.
    • This method can aid in selecting the optimal amputation level, improving patient outcomes.
    • Objective assessment of blood flow is superior to subjective clinical judgment.
