Abstract
Importance: Autologous platelet-rich plasma (PRP) has received widespread attention due to its physiologic healing properties, augmenting the body's natural healing process through platelet activation and release of growth factors. The effects of PRP on radiated tissue have been inadequately studied in vivo. Objective: To determine whether PRP can be used to improve viability of radiated tissue subjected to a clinically meaningful stressor, in this case a rotational skin flap. Design, Setting, Participants: This is a prospective trial using a radiated rat abdominal rotational flap model in the laboratory. Male Sprague-Daley rats were used in this study. Harvested PRP or saline control was injected into rotational flaps immediately after surgery. Progression of necrosis was documented with photo analysis. After 1 week, animals were sacrificed and flap tissue was stained and analyzed for presence of vascular tissue. Intervention: PRP versus control injection into radiated skin tissue. Main Outcomes and Measures: Percentage necrosis of rotational flap and number of vascular channels stained with CD31 present in flap tissue. Results: PRP administration helped rescue the distal flap from necrosis, achieving viability similar to nonradiated controls. Superficial vascularity was similarly increased fivefold in radiated tissue if PRP was given postoperatively, mirroring the vascular density of nonradiated tissue. Conclusions and Relevance: PRP may enhance distal rotational flap viability after radiation, possibly by protecting superficial vessels from tissue necrosis when administered at the time of surgery.
