Summary

Dissection, injection, and surgical studies in feline cadavers and in anesthetized cats were conducted to determine the feasibility of using the gracilis muscle as the basis for a free musculocutaneous flap. The vascular pedicle of the flap consisted of the femoral artery and vein. Mean length (1.6 ± 0.2 cm) of the vascular pedicle and mean artery (1.33 ± 0.19 mm) and vein (2.55 ± 0.38 mm) diameters were satisfactory for microvascular transfer. Fluorometry revealed overlying cutaneous perfusion in the flaps on the basis of their muscle vascular pedicles. To ensure survival of the flap, the muscular branches of the femoral artery and vein supplying the gracilis muscle had to be carefully preserved during surgical elevation of the flap.
