The treatment of limb lymphedema includes conservative treatment （non-surgical） and surgical treatment. Conservative treatment can not solve the drainage dysfunction of the lymphatic system and solve the potential physiological dysfunction of the lymphatic system， and therefore can not effectively prevent the progression of the disease. Physiologic reconstruction for drainage function is particularly important. With the in-depth study of lymphatic system and the development of microsurgical technology， supermicrosurgical lymphaticovenular anastomosis has been widely used in clinical practice because of its significant long-term efficacy， less trauma， fewer surgical complications and low cost. In this paper， the relevant domestic and foreign literatures were reviewed from the three aspects： The development of lymphaticovenular anastomosis， the operation methods， the existing problems and the solutions， to provide reference for the selection of surgical methods.
