Abstract：
PURPOSE:Although an increase in flap perfusion by incorporating multiple perforators has been demonstrated with free perforator flaps, whether the same efficacy can be achieved with pedicled flaps remains unclear, due to concerns regarding pedicle tension or kinking during flap transposition. The aim of this report was to investigate the reliability of multiple perforator-based pedicled flaps in a series of clinical cases. PATIENTS AND METHODS:Twenty-six patients undergoing soft tissue reconstruction using multiple perforator-based pedicled flaps from 2008 to 2012 were reviewed. The causes of the defects were oncologic (n = 15) or chronic wounds (n = 11). The defect sites were the trunk (n = 19), lower extremities (n = 4), head and neck (n = 2), and upper extremities (n = 1). Diverse flap types were used, including the superior gluteal artery perforator flap, the lateral femoral circumflex artery perforator flap, the medial femoral circumflex artery perforator flap, and the thoracodorsal artery perforator flap. The flaps were transposed in a rotation-and-advancement manner after skeletonizing each perforator and proximally dissecting the pedicle. The donor site was closed primarily. RESULTS:Mean flap size was 125.2 cm2 , and the mean number of perforators used was 2.3 (2-5). The mean angle of pivotal rotation for flap transposition was 132.8°. No rotation-related problems including pedicle kinking or twisting developed, and all flaps survived completely. No significant donor-site morbidity was observed. The mean follow-up period was 38.1 months. CONCLUSIONS:This report suggests that through meticulous dissection of pedicles of sufficient length, the multiple perforator-based pedicled flaps can be successfully transposed while minimizing the risk of pedicle tethering. © 2015 Wiley Periodicals, Inc.
