title: Flow-through anterior thigh flaps with a short pedicle for reconstruction of lower leg and foot defects.
abstract: New flow-through perforator flaps with a large, short vascular pedicle are proposed because of their clinical significance and a high success rate for reconstruction of the lower legs. Of 13 consecutive cases, the authors describe two cases of successful transfer of a new short-pedicle anterolateral or anteromedial thigh flow-through flap for coverage of soft-tissue defects in the legs. This new flap has a thin fatty layer and a small fascial component, and is vascularized with a perforator originating from a short segment of the descending branch of the lateral circumflex femoral system. The advantages of this flap are as follows: flow-through anastomosis ensures a high success rate for free flaps and preserves the recipient arterial flow; there is no need for dissecting throughout the lateral circumflex femoral system as the pedicle vessel; minimal time is required for flap elevation; there is minimal donor-site morbidity; and the flap is obtained from a thin portion of the thigh. Even in obese patients, thinning of the flap with primary defatting is possible, and the donor scar is concealed. This flap is suitable for coverage of defects in legs where a single arterial flow remains. It is also suitable for chronic lower leg ulcers, osteomyelitis, and plantar coverage.
