Ischemia-reperfusion (IR) is a pathological condition characterized by an initial restriction of blood supply to an organ followed by subsequent restoration of reperfusion associated with exacerbation of tissue damage. For pre-hospital emergency situations and surgical procedures, tourniquet or femoral artery ligation are widely used to stop extremity hemorrhage or create a bloodless operating field. To fully evaluate the underlying mechanisms in IR pathophysiology and potential therapeutic options, we compared tourniquet- and femoral artery ligation-induced IR injuries in the hindlimb of mice. We found that tourniquet/IR-induced acute hindlimb injuries are more severe than those induced by femoral artery ligation/IR, including alteration …
