Role of Supermicrosurgical LVA for Lower Limb Lymphedema

Vascularized lymph node flap transfer (VLNT) was believed to be the treatment of choice for moderate-to-severe lymphedema. Recent publications have supported the use of supermicrosurgical lymphaticovenous anastomosis (LVA) for treating severe lymphedema. This study hypothesizes whether LVA can be performed on post-VLNT patients seeking further improvement.
