Reduced compression pressure using inelastic materials effectively improves venous hemodynamics in mixed ulcers. This approach enhances venous reflux and ejection fraction without compromising arterial inflow, offering a safe treatment option.

Area of Science:

  • Vascular Medicine
  • Phlebology
  • Wound Healing

Background:

  • Arterial involvement occurs in 15-30% of venous ulcers, necessitating careful compression therapy.
  • Reduced compression pressure is crucial in mixed ulcers to avoid impairing arterial pressure.
  • The efficacy of reduced compression on venous hemodynamics requires further assessment.

Approach:

  • Measured venous reflux and ejection fraction (EF) in patients with venous incompetence.
  • Applied various elastic and inelastic compression devices with pressures from 20-60 mmHg.
  • Simultaneously recorded compression pressure with venous reflux and EF assessment.

Key Points:

  • Inelastic compression materials are effective in improving venous hemodynamics at reduced pressures (20-40 mmHg).

  • Higher pressures maximally reduce venous reflux and increase EF.
  • Reduced compression pressure, when using inelastic materials, improves venous hemodynamics without impairing arterial inflow.

    • Conclusions:

    • Inelastic materials generate higher standing pressure than elastic ones, even at reduced supine pressures (e.g., 40 mmHg).
    • This pressure effectively reduces or abolishes venous reflux and normalizes ejection fraction.
    • Modified compression pressure with inelastic materials significantly improves venous hemodynamics in mixed ulcers without arterial compromise.
