Plastic Surgery Reconstruction of Chronic/Non-Healing Wounds

Abstract

In western countries, approximately 1 % of individuals are affected by chronic wounds during their lifetime. Due to changing demographics, this incidence will likely increase in the future. Additionally, the high prevalence is accompanied by substantial treatment expenditures. Therefore, it is of global interest to find effective treatment algorithms. In this article, we present up-to-date solutions for treating chronic / difficult to heal and complex wounds by means of plastic and reconstructive surgery. We outline the principles of chronic wounds and how to perform an appropriate diagnosis. Close cooperation and interdisciplinary exchange are important for optimizing treatment. We report the principles of wound debridement and the role of negative pressure wound therapy. Moreover, we discuss the state of the art of defect reconstruction by means of skin grafting, with or without acellular dermal matrices, local tissue transfers and free tissue transfers. In very complex cases, the local macrovascular blood flow is greatly reduced and there are few, if any, recipient vessels for free flap reconstruction. We discuss the role of arteriovenous loops to overcome this problem.
