BackgroundExtremity lymphedema can occur bilaterally with different severities on each side. The aim of this study is to investigate the treatment outcomes of such patients with bilateral extremity lymphedema of different severities.Patients And MethodsBetween 2013 and 2017, patients with bilateral extremity lymphedema of different severities according to the Taiwan Lymphoscintigraphy Staging (TLS) system were retrospectively reviewed. Ipsilateral vascularized lymph node transplantation (VLNT) was indicated in TLS total obstruction and contralateral lymphovenous anastomosis (LVA) in TLS partial obstruction with patent lymphatic vessels on indocyanine green lymphography. Outcomes were assessed using circumference improvement, frequency of cellulitis, and lymphedema-specific quality of life (LYMQoL) questionnaires.ResultsA total of 10 patients with bilateral extremity lymphedema with median age of 63 (range 12-75) years were included. The median symptom duration of the lymphedematous limb was 60 (range 36-168) months and 12 (range 1-60) months in the VLNT and LVA group, respectively (p < 0.05). At average follow-up of 37.5 (range 14-58) months, the average limb circumference improvement was 2.4 (range - 3.3 to 7.8) cm in the VLNT group and 2.3 (range 0.3-7) cm in the LVA group (p = 1). The median episodes of cellulitis decreased significantly from 4 to 0.5 and 1 to 0 times/year in the VLNT and LVA group, respectively (p = 0.02, p = 0.06). The overall LYMQoL score improved from 4.5 preoperatively to 7.5 postoperatively (p < 0.01).ConclusionsLimb-specific VLNT and LVA selected by TLS effectively treated bilateral extremity lymphedema with different severities.
