Possibilities for revascularization and closure of wound defects in lower limbs with critical ischemia through free gracilis flap transfer: review of 3 cases

This article presents three clinical cases of lower limb revascularization with closure of trophic defects using free gracilis flap transfer; two patients with Buerger's disease and one patient with type 2 diabetes mellitus. In these cases, we also describe and discuss direct or indirect evidence of indirect revascularization of ischemic tissues by means of the flap, as well as the advantages and limitations of the free gracilis muscle flap.
