Objective: Venous leg ulcers (VLUs) caused by chronic venous insufficiency are difficult to treat. Outcomes after compression therapy and the current standard of care often used in conjunction with other options vary widely. We examined the effects of foam inserts on sub-bandage pressures in patients with VLUs and compared use of foam inserts in elastic and inelastic compression bandaging. Methods: Six patients (≥20 years old) with VLUs and skin perfusion pressure &gt;40 mmHg were included. Each patient underwent weekly treatment regimens of debridement, dressing changes, and dual sponge-insert application followed by elastic (n=3) or inelastic (n=3) compression bandaging. The median resting sub-bandage pressures of the ulcer beds, wound sizes, and healing percentages were recorded. Wound beds were biopsied before and after treatment for histological assessment. Nine healthy volunteers served as controls during preliminary testing. Results: With proper sub-bandage pressures (&gt;35 mmHg), the average healing time was 88.0±66 days, which was shorter than anticipated (i.e., ≥6 months). Combining large and local sponge-foam inserts increased sub-bandage pressures regardless of the compression bandage selected, with marked improvements seen in deeper wounds. Conclusion: Layering one or two sponge-foam inserts beneath compression bandages facilitates uniform and optimal wound-bed pressure, which accelerates the healing of VLUs.
