Non-healing surgical wounds is a risk in certain patients. Recently, allogenic plasma-rich-platelet (PRP) is used such as regenerative treatment of different non-healing surgical wounds. Purpose. We explore the potential role of using platelet-derived growth factors from single donor PRP, with a freeze-thaw process, for the treatment of surgical scar ulcer. Methods. We have used a PRP preparation protocol that involved a single cycle of centrifugation at a mean speed of 2400–2800 rpm of donor blood taken with an apheresis machine. Results. To our knowledge, this is the first study using the platelet-derived growth factors (PDGF) from single donor apheresis, with a freeze-thaw process. Four weeks after daily application of al-PRP, the ulcer progressed satisfactorily; at six weeks, the ulcer had healed. Conclusion. We concluded that the healing of a surgical wound observed in our case, is promising and suggests that al-PRP might play a role in treating surgical scar ulcers. This must be confirmed in future studies.
