Platelet-rich plasma treatment for chronic wounds: A case report and literature review

Wound healing is a complicated process that can be heavily influenced by patient comorbidities, in some cases leading to a chronic non-healing wound. Evidence presented in the medical literature supporting the clinical use of autologous platelet-rich plasma (PRP) in treatment of such wounds is becoming increasingly compelling. Mechanisms involved include complex interactions between the patient's thrombocytes, cytokines, and growth factors.

We present a case of a 72-year-old male patient with a long-standing chronic wound and multiple comorbidities. Over the course of more than 7 months, the patient was unsuccessfully treated with all routinely used measures, including different dressing approaches. Multiple antibiotic regimens were administered for wound infection, with repeated evaluation of microbiological swab results. Finally, after three PRP applications, the wound showed clinical improvement with complete restitution of the epithelial layer of the skin.

PRP treatment may be beneficial to reduce healing time in chronic wounds.
