Effect of negative pressure wound therapy for legs in complex wound diabetic patients: Therapeutic challenge and review

Diabetic foot is one of the main chronic complications caused by diabetes mellitus and can lead to limb amputation. Among the various wound treatment options, negative pressure wound therapy is a treatment modality based on vacuum-sealed drainage and vacuum-assisted closure to create a localized controlled negative pressure environment. In this case report, the patient sought medical attention and underwent surgical debridement of the dorsum of the right foot. Upon worsening of the wound condition, the patient was referred to our hospital for debridement and Renesys Smith Nephew dressing was implanted. After complete coverage of the granulation tissue without infection, elastic suturing was performed in the leg compartment to reduce the size of the dermis and epidermis graft. The patient then underwent a dermal matrix implant procedure, and an epidermis graft was removed from the ipsilateral thigh and placed on the wound. The aim of this study is to report a therapeutic challenge in an extensive wound in diabetic foot using a dressing negative pressure wound therapy and multidisciplinary treatment.
