Abstract

Abstract: Soft tissue sarcomas are a rare group of malignant tumors that often require an extensive surgical resection to be safely treated. When they are localized in the upper medial thigh, this treatment inevitably leads to large defects frequently causing a series of early and late postoperative complications. Among these, lymphocele and lymphedema are rather common and should try to be avoided. Many solutions with a demonstrated efficacy have been described for this purpose after groin dissection procedure, ranging from lymphovenous anastomosis to pedicled or free flaps. Anyway, there is much less information regarding the medial thigh. Here we present a case of resected sarcoma involving the adductors compartment reconstructed using a pedicled deep inferior epigastric (DIEP) flap with lymphatic tissue transfer, combined with preventive lymphovenous anastomosis (LVA) performed at the superior‐edge‐of‐the‐knee incision (SEKI) point. A 58‐year‐old patient presented a 10 cm × 12 cm soft tissue defect after margin free sarcoma removal. To fill this defect, we harvest a 24 × 9 cm pedicled DIEP flap conserving its lymphatic vessels running from the upper margin to the right groin lymphnodes. Then we rotated it maintaining the lymphnodes in their original site and moved it through an inguinal tunnel in the area of the defect. The distal part was de‐epithelized and folded down to cover the deeper region. The postoperative course was uneventful and at the 6 months follow up the patient showed a good outcome with no swelling and no signs of tumor relapse. This result therefore may suggest that this kind of combined treatment might be an effective technique to prevent all those complications linked to the impairment of lymphatic system drainage in the proximal medial thigh.
