title: [Microsurgical Autologous Lymph Vessel Transplantation: Does Harvesting Lymphatic Vessel Grafts Induce Lymphatic Transport Disturbances in the Donor Limb?].
abstract: OBJECTIVE
  The aim of this study was to determine whether the extirpation of lymphatic vessels induces lymphatic transport disturbances in the donor limb of patients following the harvest of lymph vessel grafts.
  
  
  METHODS
  A total of 19 consecutive patients (15 females, 4 males; mean age 51.5 years, range 21.8-72.3) were examined by lymphoscintigraphy before and after surgery. The patients had previously been diagnosed with upper or lower limb lymphoedema in accordance with the criteria of the International Society of Lymphology, and autologous lymph vessel transplantation had been intended for treatment. Since only patients with normal scintigraphic tests at the harvesting site were considered for treatment, all consecutive patients (n=19) had normal scintigraphic tests of the donor limb prior to surgery. In order to quantify the visual scintigraphic findings, a well established numeric transport index (TI) was used, which combined 5 visual parameters of transport kinetics. To that end, the following visually assessed criteria were evaluated: temporal and spatial kinetics, radiopharmaceutical distribution pattern, time to appearance of inguinal lymph nodes, qualitative visualisation of lymph nodes and lymph vessels.
  
  
  RESULTS
  All patients underwent a preoperative scintigraphic baseline study and a postoperative scintigraphic follow-up after autologous lymphatic vessel grafting. The mean time period from the baseline study to the date of microsurgical lymph vessel transplantation was 3.5 months (median 2.5 months). The scintigraphic follow-up was performed 48.6 months (median 57.8 months) following transplantation. In all patients the postoperative TI was very close to the TI calculated in the preoperative baseline scintigraphy, and all TIs were within the normal range (TI<10). The absolute value of deviation of pre- vs. post-operative transport indices was calculated to be 0.2 on average (maximum 0.4).
  
  
  CONCLUSIONS
  The results show that microsurgical transfer of lymph vessel grafts is possible without compromising lymphatic drainage of the donor limb if safety precautions are taken into account.
