title: The truly distal lateral arm flap: rationale and risk factors of a microsurgical workhorse in 30 patients.
abstract: The forearm part of the extended lateral arm flap may be separately raised on the most distal septocutaneous perforator of the posterior collateral radial artery. This truly distal lateral arm flap shares most of the advantages of the radial forearm flap and is associated with less donor site morbidity. From April 2000 to March 2004, we used 30 such flaps as the fasciocutaneous free flap of choice, mostly for reconstructions in the head and neck region. The eventful postoperative course observed in 5 of these flaps motivated us to evaluate the rationale and risk factors of this procedure. We prospectively analyzed the influence on the incidence of partial or complete flap loss of 19 patient-related or procedure-related characteristics that may have acted as risk factors. None were found to be of statistical significance. We found the distal lateral arm flap to have a less robust vascular anatomy than the radial forearm flap, resulting in the need for advanced surgical expertise to raise and handle it. As we recognized the difficulty of this flap to be associated predominantly with this anatomy of its vascular pedicle, we now take a more liberal stand toward the possibility of intraoperative conversion to the use of a radial forearm flap.
