title: Reconstruction of soft tissue defects in the extremities with a pedicled perforator flap: series of 25 patients.
abstract: Since the introduction of perforator-based flaps, new flaps have been described for reconstruction of soft tissue defects in the extremities. Pedicled perforator flaps, often called propeller flaps, are based on a single perforator and are local axial flaps that can be rotated up to 180(0) with the single perforator as the pivotal point. Pedicle perforator flaps have gained popularity because they have a shorter operating time than free flaps. However, some concern has been raised about their reliability. Here we report our results of 11 soft tissue reconstructions in the lower leg and 14 in the upper extremity. The defects were mostly traumatic or caused by release of burn scars. The mean size of the flaps in the lower leg was 52 cm(2) (range 126-15 cm(2)). In the upper extremity it was 24 cm(2) (range 12-35 cm(2)). All patients were followed until the wound had healed. In the upper extremity there was only one partial necrosis of the flap, and one patient had an infected wound. One haematoma was evacuated postoperatively, and all the rest healed uneventfully. In the lower leg we had one total necrosis and one partial necrosis of the flap and one infected wound. A free scapular flap was used for salvage in one case, and revision and skin grafting in two. The pedicled perforator flap is reliable, particularly in the upper extremity. The operation is quick and can be done under regional anaesthesia. The flap is thin and has a local texture that gives a good functional and aesthetic result. The pedicled perforator flap is a little unpredictable in the lower leg, probably because the directions of the vessels that arise from the perforator are not consistent.
