Omental vascularized lymph node transplant for the treatment of breast lymphedema: A case report.

Breast lymphedema is a type of breast cancer related lymphedema that leads to significant discomfort and negative impact on body image. Conservative therapy and lymphovenous bypass have been previously described as possible treatment methods for breast lymphedema, however, a unified approach to treatment is lacking. The current report describes a case of breast lymphedema successfully treated with vascularized lymph node transfer (VLNT) after failed attempt at management with conservative therapy. The patient is a 48-year-old female with right-sided breast cancer who underwent breast conservation therapy in 2015 and subsequently developed pain and swelling of the right breast. The diagnosis of breast lymphedema was supported by clinical evaluation as well as MRI, lymphoscintigraphy, and lymphography. In consultation with a breast surgeon, breast lymphedema was determined not to be an indication for mastectomy. The patient was offered and underwent an omental VLNT to the right breast. A 20 cm segment of omentum with associated gastroepiploic vessels and lymph nodes was harvested, transferred to the right axilla and gastroepiploic vessels were anastomosed to the recipient thoracodorsal vessels. The patient tolerated the procedure well and there were no complications. Additional donor sites were considered, such as the groin and submental regions, but an omental flap was favored in this case because of the lower risk of donor site lymphedema. In the years following, the patient reported significant improvement in symptoms as well as objective reduction of edema on MRI. We propose the consideration of VLNT for breast lymphedema refractory to other methods of management.
