The use of vacuum-assisted wound closure to enhance skin graft acceptance in a horse

Abstract

A 16-year-old horse was admitted to the clinic of the Department of Surgery and Anesthesiology of Domestic Animals of the Faculty of Veterinary Medicine (Ghent University) for the treatment of a very large, non-healing wound extending over the dorsomedial and dorsolateral aspects of the left metatarsus. Surgical debridement of exuberant granulation tissue and new bone was performed under general anesthesia, followed by standard wound care under a bandage. Once a new bed of healthy granulation had formed, skin grafting was performed using the punch graft method. Due to the presence of a significant amount of wound exudate, cast immobilization was considered to be contraindicated. Instead, vacuum-assisted closure (VAC) therapy was used as a method of securing the skin grafts to the wound bed during the first days post-operatively. After five days of VAC therapy, the wound dressing was removed and an acceptance of nearly 100% of the punch grafts was observed. Complete epithelialization of the wound was evident 42 days after skin grafting. As far as the authors know, this is the first report describing the use of VAC therapy as a method of wound management in combination with punch grafting on the distal limb of a horse
