  Purpose
Compare the efficacy of using an absorbent foam silver dressing (Mepilex Ag) versus the equivalent dressing without silver in subjects suffering from venous leg ulcer or mixed ulcer with an ABPI ≥ 0.8 and with inflammatory signs. Efficacy will be defined as absolute wound size reduction.

    • pain between dressing changes
    • exuding wounds
    • erythema on peri-wound skin

Exclusion Criteria:

  • > 10% necrotic (black) or fibrinous (yellow) tissue covering the wound bed
  • Infected wounds in need of systemic antibiotic treatment
