Lymphaticovenular Anastomosis for Lymphorrhea after Expander-based Breast Reconstruction: A Case Report.

Refractory axillary lymphorrhea is a postoperative complication of breast cancer with no established standard treatment. Recently, lymphaticovenular anastomosis (LVA) was used to treat not only lymphedema but also lymphorrhea and lymphocele in the inguinal and pelvic regions. However, only a few reports have been published on the treatment of axillary lymphatic leakage with LVA. This report presents a case of successful treatment of refractory axillary lymphorrhea after breast cancer surgery with LVA. A 68-year-old woman underwent nipple-sparing mastectomy for right breast cancer, axillary lymph node dissection, and immediate subpectoral tissue expander placement. Postoperatively, the patient developed refractory lymphorrhea and subsequent seroma around the tissue expander, and underwent postmastectomy radiation therapy and frequent percutaneous aspiration of the seroma. However, lymphatic leakage persisted, and surgical treatment was planned. Preoperative lymphoscintigraphy showed lymphatic outflow from the right axilla to the space around the tissue expander. There was no dermal backflow in the upper extremities. To reduce lymphatic flow into the axilla, LVA was performed at two sites in the right upper arm. The lymphatic vessels used for anastomosis were 0.35 mm and 0.50 mm in diameter, and each was anastomosed to the vein in an end-to-end fashion. The axillary lymphatic leakage stopped shortly after the operation, and there were no postoperative complications. LVA may be a safe and simple option for the treatment of axillary lymphorrhea.
