Abstract

The incorporation of skin flaps in wound closure management with its cosmetic implications has appeared as a gleam of hope in providing desirable outcomes. Given the influence of extrinsic and intrinsic factors, skin flaps are prone to several complications, including ischemia-reperfusion injury (IRI). Numerous attempts have been undertaken to enhance the survival rate of skin flaps entailing pre/post-conditioning with surgical and pharmacological modalities. Various cellular and molecular mechanisms are employed in these approaches in order to reduce inflammation, promote angiogenesis and blood perfusion, and induce apoptosis and autophagy. With the emerging role of multiple stem cell lineages and their ability to improve skin flap viability, these approaches are increasingly being used to develop even more translationally applicable methods. Therefore, this review aims at providing current evidence around pharmacological interventions for improving skin flap survival and discussing their underlying mechanism of action. © 2023 British Association of Plastic, Reconstructive and Aesthetic Surgeons
