Complex Soft Tissue Defects in Operative Urology: Pedicled Perforator Flaps of the Anterior Lateral Thigh for Tissue Reconstruction of the Lower Trunk

Abstract

<b><i>Background:</i></b> Complex soft tissue defects involving the lower abdomen, perineum, and groin (LAPG) represent reconstructive challenges following urologic surgery. Consequently, these often require an interdisciplinary approach involving plastic surgery. While pedicled flaps from the lower abdomen are a reliable option, previous placement of colostomies and urinary urostomies renders these flap types unavailable. Here, the pedicled anterolateral thigh perforator (ALT) flap represents a reliable pedicled alternative which can harvest from the thigh. <b><i>Materials and Methods:</i></b> A retrospective data analysis of pedicled perforator flaps harvested from the thigh to reconstruct soft tissue defects was conducted. Seven patients treated in the urology department with soft tissue defects following tumor resection, infection, and dehiscence were included. <b><i>Results:</i></b> In all patients, the ALT flap was utilized successfully to reconstruct soft tissue defects up to 450 cm² in size. All flaps survived. In 1 case, prolonged wound healing was observed. All defects were adequately addressed with no recurrence of dehiscence or fistula formation. <b><i>Conclusions:</i></b> Pedicled perforator flaps represent a valid option for the soft tissue reconstruction of the lower abdomen and perineum when a pedicled rectus abdominis flap is no longer available. This flap is, therefore, a good option in an interdisciplinary approach to soft tissue reconstruction, especially following urologic surgery, which is predominantly performed in the LAPG region.
