Duplex scan effectively quantifies venous reflux, showing increased reflux correlates with advanced venous disease stages. The greater saphenous vein is a primary contributor, and intervention may be beneficial even with deep vein involvement.

Area of Science:

  • Vascular Medicine
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Venous reflux quantification by duplex scan lacks standardized parameters.
  • The role of superficial versus deep venous involvement in disease progression is debated.
  • Correlation between venous reflux severity and clinical disease stages requires clarification.

Purpose of the Study:

  • To compare various duplex scan quantitation parameters for venous reflux.
  • To assess the relationship between reflux parameters and different venous disease manifestations.
  • To investigate the association between reflux and clinical stages of venous disease.

Main Methods:

  • Classification of venous conditions into seven stages.
  • Quantification of venous reflux using parameters like velocity, flow, and volume via duplex scan.

  • Analysis of deep and superficial venous system contributions.

    • Main Results:

    • Most quantitation variables (velocity, flow, volume) showed significantly increased reflux with disease progression (normal to ulcer).
    • Reflux time was less consistent; chronic edema often showed no increased reflux.
    • Superficial venous reflux, particularly from the greater saphenous vein, was a major contributor across all disease stages.

    Conclusions:

    • Quantitation methods for venous reflux are largely equivalent.
    • Increased deep and superficial venous reflux is associated with advanced disease.
    • Greater saphenectomy may be a valuable intervention, irrespective of deep vein reflux presence.
