Current treatment modalities for chronic leg ulcers are time consuming, expensive, and only moderately successful. Recent data suggest that creating a sub-atmospheric pressure by Vacuum Assisted Closure (V.A.C.®) therapy supports the wound healing process. Here, we studied the efficacy of V.A.C.® in the treatment of chronic leg ulcers prospectively.

Primary Outcome Measures:
  • Time-to-complete-healing: i.e. the period between initial preparation of the wound and 100% epithelialisation with the primary endpoint being time-to-complete-healing.

Secondary Outcome Measures:
  • 1)duration of the wound-bed preparation stage
  • 2)percentage of leg ulcer recurrences within one year (i.e. an epithelial breakdown anywhere along or within the index ulcer region)
  • 3)skin-graft survival, where applicable (i.e. percentage of successfully adhered skin grafts after 4 days of complete bed rest and compression or VAC® treatment)
  • 4) the quality of life
  • 5) pain scores
  • 6) the total time needed for wound care until complete wound closure
  • 7) the costs per ulcer.

Inclusion Criteria:

patient with a chronic leg ulcer (> 6 months) without healing signs and satisfies to one or more criteria:

  • Venous (venous insufficiency of the deep or superficial system without an arterial incompetence)
  • Combined venous/arterial (venous insufficiency of the deep or superficial system with an ankle/brachial index of 0·60 - 0·85)
