Ischemia as well as ischemia-reperfusion injury (IRI) can cause serious tissue damage and therefore is a feared complication in reconstructive surgery. This is the reason why researchers around the world invest their efforts to improve tissue viability after ischemic events. Tissue conditioning offers a broad scope of different techniques which can be applied pre-, peri- or postoperatively to adapt the affected tissue to the subsequent stress during and after ischemia to prevent or minimize IRI. The different ways of tissue conditioning in flap surgery include surgical delay, ischemic conditioning, remote ischemic conditioning as well as thermic preconditioning and other techniques, using growth factors, pharmaceutical agents, extracorporeal shock waves as well as stemm cells. Therefore, we want to shed some light on the effects of ischemia and ischemia-reperfusion injury and further illustrate the different strategies of tissue conditioning with special concern to flap surgery but also regarding wound healing in general.
