Study of Efficacy of Autologous Platelet Rich Fibrin in Chronic Non-Healing Ulcers of Leg

Abstract

Introduction: Platelet-rich fibrin (PRF) is the newer treatment option for treatment of chronic non-healing ulcers of leg and it contains various growth factors which boosts the wound healing. Objectives: To detect the efficacy of autologous PRF dressing in chronic non-healing leg ulcers and to assess the reduction in ulcer area at the end of each week. Materials and Methods: 30 patients (17 females, 13 males) were taken in this prospective study with informed consent. PRF was prepared by drawing 10cc venous blood and directly centrifuging it at 3000rpm (approximately 400g) for 10 minutes without adding anticoagulant. Three fractions were formed consisting of red coloured lower fraction containing RBCs, middle fraction containing PRF and upper fraction consisting of upper straw coloured platelet poor plasma (PPP). PPP fraction was discarded; middle PRF fraction was collected by separating it from the lower RBC fraction with forceps and scissors. PRF was then applied over the healthy bed of chronic non-healing ulcers every week till the wound heals. Reduction in ulcer at the end of each week is assessed by calculating area (Length×Width×0.7854). Results: The mean size of the ulcers was 10.4 cm2 initially; mean duration of ulcer was 4.7months. Complete healing required minimum 3 and the maximum 8 sittings (mean 4) no adverse events seen. Conclusion: We conclude that PRF dressing can be used as it is effective, safe, outpatient procedure in chronic non-healing leg ulcers.
