Trans-vastus Intermedius Transfer of the Pedicled Anterolateral Thigh Flap for Posterior Thigh Reconstruction

Abstract

Summary: Proximal, posterior thigh wounds from oncologic or traumatic defects can be difficult wounds to reconstruct if local flap options have been sacrificed during the trauma or oncologic resection. Free flap options to cover these defects are also difficult because of the lack of convenient recipient vessels in the region. The authors present 2 cases (oncologic and traumatic) wherein a myocutaneous anterolateral thigh (ALT) flap was harvested and tunneled from the anterior muscle compartment to the posterior muscle compartment of the thigh through a medially based transmuscular tunnel, decreasing the required pedicle distance to the wound. This technique of transmuscular tunneling of the ALT flap expands the indications and utility of the ALT flap to cover posterior thigh wounds.
