Use of disposable negative pressure wound therapy on split-thickness skin graft recipient sites for peripheral arterial disease foot wounds: A case report

Abstract

Split-thickness skin graft (STSG) helps to promote healing of wounds by providing a viable soft tissue cover. However, the success of which is influenced by how well it takes to the recipient site. Studies have demonstrated that negative pressure wound therapy (NPWT) is an excellent modality to promote graft survival. Technological advancements have made possible the invention of disposable, ultraportable, and mechanically operated versions for improved user experience. Alas, little has been discussed about their benefits on STSG. Therefore, the purpose of this case report is to highlight the effective use of disposable NPWT on freshly applied STSG. We report here a novel use of the disposable NPWT (SNAP therapy system) for STSG recipient sites in two patients with peripheral arterial disease (PAD) foot wounds. In both patients, there was 100% STSG uptake, and the lightweight disposable NPWT system makes for a more cost-effective and comfortable experience for patients. Disposable NPWT may be a feasible alternative to conventional NPWT to aid with STSG uptake for PAD foot wound recipient sites.
