A digital surface scanner can detect vascular perfusion disorders by monitoring skin color changes. This non-invasive tool objectively identifies early signs of flap failure in reconstructive surgery.

Area of Science:

  • Biomedical Engineering
  • Surgical Innovation
  • Medical Imaging

Background:

  • Monitoring vascular perfusion is critical in reconstructive surgery to prevent flap failure.
  • Early detection of vascular compromise is essential for successful tissue transplantation.
  • Current methods for monitoring perfusion can be invasive or lack objectivity.

Purpose of the Study:

  • To evaluate the efficacy of a digital surface scanner in detecting vascular perfusion disorders.
  • To assess the scanner's ability to monitor skin color changes indicative of compromised blood flow.
  • To determine if the scanner can differentiate between arterial and venous vascular issues.

Main Methods:

  • 160 forearm skin surface scans were performed using a TRIOS 3D scanner.

  • Vascular compromise was simulated via intermittent arterial and venous blood supply occlusion.
  • Skin color changes were analyzed using hue, saturation, and value (HSV) color scale.
  • Paired t-tests were used to analyze color differences between normal and compromised skin.

    • Main Results:

    • Significant differences in skin color were observed between normal and vascularly compromised skin (P<0.01).
    • The digital surface scanner successfully distinguished between arterial occlusion and venous congestion (P<0.01).
    • Objective, quantifiable color data correlated with simulated perfusion deficits.

    Conclusions:

    • Digital surface scanning is a viable, non-invasive method for monitoring skin perfusion.
    • This technology offers an objective tool for early detection of vascular compromise in reconstructive surgery.
    • The TRIOS 3D scanner shows promise in enhancing the safety and success rates of flap surgeries.
