title: Angio computed tomography preoperative evaluation for anterolateral thigh flap harvesting.
abstract: The vascular anatomy of the anterolateral thigh flap (ALTF) has many possible variations, and none of the currently used mapping techniques (eg, Echo Color Doppler) gives a thorough knowledge of all details. Among the last generation of angiographic diagnostic techniques, multi detector computed tomography, popularly known as Angio CT, has emerged as an outstanding noninvasive operator independent option, and has been described for deep inferior epigastric perforator and pedicled transverse rectus abdominis muscle planning. This study was conducted to evaluate its usefulness prior to ALTF harvesting.Nine consecutive patients were considered for oral or lower extremity reconstruction with the ALTF. After written informed consent was obtained from all patients, a preoperative Angio-CT study was performed for surgical planning. Accurate identification of septocutaneous or musculocutaneous perforator vessels was achieved and their location, course, and anatomic variations were reported and influenced surgery. Angio CT allows a complete vascular study of the donor area of the ALTF and evaluation of the best perforator vessels before surgery allows surgeons to get an ideal planning of the flap. This imaging method is currently proposed to every patient undergoing ALT flap reconstruction.
