Pedicled double-paddle vertical posteromedial thigh flap for double-layer closure and reconstruction of upper thigh defect after sarcoma resection: A case report.

Large soft tissue defects in the anterior upper thigh region represent a challenging problem in reconstructive surgery. Sarcomas are rather commonly localized in this area and they may reach extensive dimensions before surgery. The debulking procedures must be radical, which often leads to a displacement of major neurovascular structures. In the present work, we report the use of a pedicled double-paddle vertical posteromedial thigh (vPMT) flap to reconstruct a 16 cm × 8 cm soft tissue defect with exposure of the superficial and deep femoral vessels after resection of a myxoid liposarcoma. The vPMT flap was based on two perforators of the profunda femoris artery. Therefore, the cutaneous island could be split into two islands measuring 12 cm × 6 cm and 9 cm × 6 cm, which were exploited to fill the dead space below and over the vessels, reaching a satisfactory volume restoration and tension-free skin closure. The further post-operative course was uneventful. The perforator dissection might be complex and requires a good experience, however, we believe that in similar cases the pedicled double-paddle vPMT flap can be a valid solution when other options are not feasible. Moreover, this allows avoiding a free microsurgical transfer and fulfills the dictum of replacing "like-with-like tissue". No characterizations of the employment of a pedicled chimeric vPMT flap for locoregional multilayer reconstruction are available so far.
