Lymphoedema of the arm is a possible consequence of the treatment of breast cancer, in particular after axillary lymph node surgery or radiotherapy of the axilla. The lymphatic drainage of the limb is interrupted, fluid accumulates, and the arm swells.
It is a distinct condition from breast reconstruction, with its own assessment. The first line of management is medical and is led by lymphoedema therapists: compression, manual drainage, and skin care. Surgery is considered where that management has been organised and the limb remains symptomatic.
Both surgical options are microsurgical. Dr Colson holds an Interstate Diploma in Microsurgery. Whether either applies, and which, depends on the assessment of the lymphatic system, and is decided in consultation.
Lymphaticovenous anastomosis (LVA)
LVA connects a lymphatic vessel of the arm directly to a nearby small vein, under high magnification, so that lymph that can no longer pass drains into the venous circulation. The incisions are short and the procedure is superficial.
Vascularised lymph node transfer
Lymph node transfer moves a small group of lymph nodes, with their artery and vein, from a donor site to the affected region. The vessels are reconnected under the microscope, and the transferred nodes are intended to re-establish drainage locally.
