Double autologous lymph node transplantation (ALNT) at the level of the knee and inguinal region for advanced lymphoedema of the lower limb (elephantiasis)

Abstract

Primary lower-limb lymphoedema is a chronic, progressive and debilitating condition with a difficult management, especially in advanced cases (elephantiasis). Recently, autologous lymph node transplantation (ALNT) appears to be a promising treatment for extremity lymphoedema. A case of a double ALNT for an advanced primary lower-limb lymphoedema is here reported: a contralateral inguinal lymph node flap was transferred to the knee and, in a second surgery, a thoracic lymph node flap was transplanted to the inguinal region. Clinical outcomes at 5 months postoperatively are very satisfactory with reduction in limb circumferences and improvement in skin quality and social impairment.
