AbstractIschemia/reperfusion-injury of skeletal muscle--pathophysiology and clinical implications. Ischemia and reperfusion of skeletal muscle occurs in acute vascular occlusion and revascularisation, in elective vascular surgery, in orthopedic surgery by means of a tourniquet, and in transplantation of muscle-containing cutaneous flaps. The ischemia sets up a cascade of events, which fully develops not prior to the moment of reperfusion. The ischemia-reperfusion-cascade is comparable to an overwhelming inflammatory reaction out of control. Depending on the duration of ischemia it prompts an injury for the muscle itself, and in some cases for the whole body. The present review discusses the main mechanisms of ischemia/reperfusion-injury in terms of cellular metabolism, endothelial function, cytokine release, and leucocyte function. Release of toxic oxygen radicals by activated leucocytes plays the pivotal role in this reaction. In addition, the clinical manifestations of ischemia/reperfusion will be reviewed as well as some of the means proposed to control this harmful reaction.
