Use of Porcine-Derived Dermal Substitutes for Treatment of Nonhealing Vascular Leg Ulcers: A Case Series

Nonhealing leg ulcers are a major health problem worldwide with a high economic burden since they require human and material resources. Moreover, nonhealing ulcers are a major nontraumatic cause of lower limb amputations. Dermal substitutes have emerged as an effective therapeutic option for treatment of skin lesions, but data on leg ulcers are scarce. We evaluated safety and efficacy of a porcine-derived dermal substitute in the treatment of chronic vascular leg ulcers. Records of patients with nonhealing ulcers seen at our unit from 2018 to 2019 were retrospectively reviewed. Wound etiology, wound area, and complications were evaluated. Each patient received one application of porcine-derived dermal substitute and was followed-up. Six patients (5 females and 1 male) with a mean age of 61.3 (52-81) years presented with nonhealing leg ulcers. After surgical debridement and wound bed preparation, porcine-derived dermal substitute was applied onto the ulcer. Granulation was satisfactory within 10 days. All wounds healed after an average time of 14 weeks. Graft take was good, and no graft loss, rejection, or associated infection were observed. In conclusion, the data presented indicate that dermal substitutes are safe and effective for treatment of chronic nonhealing vascular leg ulcers.
