Lymph node transfer for refractory infectious sites caused by trauma

Abstract

Objective: In this report, we placed focus on the immunological function of lymph nodes and performed lymph node transfer via a free flap to a site of refractory infection. Case and Results: Case 1 describes a 34-year-old male suffering from compound fractures with severe crush injuries and burns in the right ankle joint. A 20 × 15 cm skin defect was observed around the right malleolus medialis, along with denuded tendons with bacterial infection. After conservative treatment, we transferred a lymph-node-containing free superficial circumflex iliac artery perforator flap to the region, with minimum debridement. No recurrence of wound infection appeared. Case 2 describes a 73-year-old male patient suffering from extensive contused wound in the right crus. Despite conservative treatment, the tibia gradually became denuded with computed tomography and magnetic resonance imaging revealing degeneration of the tibial cortex. We performed a free superficial circumflex iliac artery perforator flap containing lymph nodes to the chronic infection area. The wound area healed successfully. Conclusion: In conclusion, lymph node transfer has a potential of treatment infection sites.
