ABSTRACT

A chronic wound is defined as a break in the skin for a long duration (6 weeks or more) or frequent recurrence. Management of such wound is challenging and requires a dermal substitute to aid wound healing. The present case aims at analyzing the effect of re-constituted bovine collagen mesh and autologous PRP in the management of chronic wound in a dog. A one-year-old, intact male, Labrador cross was presented with a history of wound on the left hind limb for past 2 months and conventional treatment resulted in vain. Clinical examination revealed extensive wound on the medial aspect of left thigh with necrotic edges. Reconstructive surgery was performed using local flap method. Suture dehiscence and necrosis noticed after 2 days due to self-mutilation. Wound edges were debrided and reconstituted collagen wet mesh was fixed over the wound bed. Subcutaneous injection of autologous Platelet Rich Plasma was administered. Disposable stainless steel skin staples were used to appose the skin in the distal wound margin. Complete wound contraction was appreciated in 60 days. Animal made an uneventful recovery.
