Resistant Chronic Venous Leg Ulcers: Effect of Adjuvant Systemic Hyperbaric Oxygen Therapy Versus Venous Intervention Alone.

was to assess the adjuvant efficacy of adding systemic hyperbaric oxygen therapy (HBOT) to definitive venous intervention for healing of resistant chronic venous leg ulcers (VLUs). From 97 chronic VLUs, 63 were subjected to a pre-study standard wound care. Thirty three ulcers failed to achieve 50% size reduction, after the 4-weeks standard care, and were allocated to be treated with: HBOT plus venous intervention (n = 17), or venous intervention alone (n = 16).
