BACKGROUND: Lymphedema remains a challenging clinical problem that often lacks curative treatment options. Recent reports have shown that microvascular lymph node transfer from the groin area into axillas of lymphedematous patients may improve lymphatic drainage, but the effect on donor-site lymphatic flow has not been studied. These patients may be more prone to develop lymphedema at donor sites as well; therefore, the authors' aim was to evaluate postoperative donor-site lymphatic function.
METHODS: The authors performed lymphatic groin flap transfer to the axilla in 13 lymphedema patients. In 10 patients, the lymph node transfer was performed simultaneously with lower abdominal breast reconstruction. Postoperative lymphatic vessel function of the donor site was evaluated by lymphoscintigraphy and limb circumference measurements. For semiquantitative evaluation of lymphatic drainage, a numerical transport index was used.
RESULTS: In six of 10 patients, postoperative lymphoscintigraphy revealed minor changes in lymphatic flow of the donor-site limbs. The transport index was considered slightly abnormal in two of 10 patients. None of the 13 patients had changes in lower limb circumferences during the 8- to 56-month follow-up.
CONCLUSIONS: Lymph node transfer can be easily combined with lower abdominal breast reconstruction, and the popularity of this technique is increasing rapidly. Even though none of our patients had developed symptoms of postoperative lymphedema, the results of the first lymphoscintigrams show that it is important to reduce the surgical trauma to the lymphatic flap donor site.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
