Abstract
Background: Chronic nonhealing ulcers of the lower extremity are a cause of morbidity and mortality. The various treatment options available are limited and unsatisfactory. Promoting wound healing with an autologous platelet membrane could be a safe, easy, and inexpensive modality. Purpose: To assess an autologous platelet-rich fibrin (PRF) membrane as a wound dressing in the treatment of chronic nonhealing leg ulcers. Methods: A prospective study enrolled 30 patients with chronic nonhealing leg ulcers. Autologous PRF was applied weekly for 6 weeks. At each visit, the ulcer healing was assessed with wound measurements and photographs. The treatment outcome was defined as a percentage in a change of area and volume of the ulcer at the end of the study period. Results: Thirty patients with chronic nonhealing leg ulcers were treated for 6 weeks. 100% improvement in area of the ulcer was seen in 43% ulcers. The mean percentage of improvement in area of the ulcer was 72%. The mean percentage of improvement in volume of the ulcer was 77%. The mean duration of healing was 5 weeks. Conclusion: This study was limited by the lack of a control group. Autologous PRF may be useful for the treatment of chronic nonhealing leg ulcers which can be done on an outpatient basis with minimum adverse effects.
