Lymphedema is the chronic disease plastic surgeons are best positioned to treat — and the most commonly mismanaged. After axillary node dissection, up to 50% of breast cancer patients develop it, and most never get the early, disciplined care that prevents progression to fibrofatty disease.

In this episode of Plastics in Practice, we review the essentials of lymphedema management — from how the lymphatic system fails to the diagnostic threshold (2 cm or 200 ml difference), staging by the International Society of Lymphology, the role of Complex Decongestive Therapy as the gold-standard nonsurgical approach, and how to think about surgery: physiologic methods like lymphaticovenous bypass and vascularized lymph node transfer, versus reductive options like liposuction and direct excision. We also cover the late complications residents should not miss — recurrent cellulitis, and the rare but devastating Stewart-Treves lymphangiosarcoma.

Key Takeaways:

• Diagnostic threshold: limb circumference difference > 2 cm or volume increase > 200 ml is clinically significant.
• Up to 50% of patients with axillary lymph node dissection develop lymphedema; only 4–7% after sentinel node biopsy.
• Complex Decongestive Therapy (CDT) is the gold-standard nonsurgical management — Phase 1 intensive (4–6 weeks), Phase 2 maintenance for life.
• ISL staging: Stage 0 latent → Stage I pitting → Stage II non-pitting fibrofatty → Stage III lymphostatic elephantiasis.
• Physiologic surgery (lymphaticovenous bypass, vascularized lymph node transfer) can reduce limb volume ~35% at 12 months in selected patients.
• Liposuction is the workhorse for non-pitting, fibrofatty lymphedema — requires ≥ 600 ml volume difference, failed 3 months of CDT, and lifelong compression after surgery.
• Stewart-Treves lymphangiosarcoma: rare but aggressive — 5-year survival < 10%, average survival 19 months after diagnosis. Always biopsy suspicious nodules in a long-standing lymphedematous limb.
