What is lymphatic surgery for lymphoedema?

Lymphatic surgery is a group of microsurgical procedures that can improve lymphatic drainage and reduce swelling caused by lymphoedema. It may be considered when symptoms persist despite conservative treatment, with the most suitable procedure depending on the condition of the lymphatic vessels and the tissues affected.

Lymphoedema develops when the lymphatic system cannot drain fluid effectively, causing a build-up in the tissues. It can be primary, resulting from abnormalities of the lymphatic system, or secondary, which may develop after cancer treatment, lymph node surgery, radiotherapy, infection or injury.

What are the symptoms of lymphoedema?

The main symptom of lymphoedema is persistent or intermittent swelling affecting part of a limb or another area of the body. The swelling may initially come and go but can become more persistent over time.

Other symptoms can include:

• A feeling of heaviness, aching or tightness in the affected area.
• Difficulty moving the affected limb or fitting into clothes, shoes or jewellery.
• Hardening or tightening of the skin and development of skin folds.
• Recurrent skin infections, including cellulitis.
• Fluid leaking through the skin in more advanced cases.

How is lymphoedema diagnosed before surgery?

Lymphoedema can usually be diagnosed through a medical history and examination, with measurements of the affected limb used to assess swelling. Further investigations may be recommended when the diagnosis is uncertain or when detailed information about the lymphatic system is needed for treatment planning.

Depending on the individual circumstances, assessment may include:

• Limb volume measurements or bioimpedance testing.
• Ultrasound or MRI to assess the tissues and exclude other causes of swelling.
• Lymphoscintigraphy to examine lymphatic drainage and identify blockages.
• Specialist lymphatic imaging to identify functioning lymphatic vessels before microsurgery.

What types of lymphatic surgery are available for lymphoedema?

Lymphatic surgery aims either to restore lymphatic drainage or to remove tissue that has accumulated as a result of longstanding lymphoedema.

The main surgical approaches include:

• Lymphovenous anastomosis (LVA): tiny functioning lymphatic vessels are connected to nearby veins, creating an alternative route for lymphatic fluid to drain.
• Vascularised lymph node transfer: healthy lymph nodes and their blood supply are transferred to the affected area to support lymphatic drainage.
• Liposuction: excess fatty tissue associated with established lymphoedema is removed to reduce the size of the affected area.

LVA can be particularly useful when functioning lymphatic vessels remain, and published evidence suggests that outcomes may be greater when surgery is performed before advanced lymphatic damage and fibrosis develop.

What can lymphatic surgery achieve?

Lymphatic surgery can reduce swelling and improve symptoms and quality of life, although it does not necessarily eliminate lymphoedema completely. Outcomes vary according to the type and stage of lymphoedema, the condition of the lymphatic vessels and the procedure performed.

A 2025 meta-analysis of prospective studies found that lymphovenous bypass was associated with an average 14.26% reduction in limb volume at one year, although results varied between individuals and studies.

What can you do to manage lymphoedema alongside surgery?

Lymphatic surgery is generally considered alongside, rather than as a replacement for, appropriate lymphoedema management.

Practical measures include:

• Following advice about compression garments.
• Keeping the affected skin clean, moisturised and protected from cuts.
• Exercising regularly according to professional advice.
• Maintaining a healthy weight and balanced diet.
• Elevating the affected limb when appropriate.

When should you seek medical help for lymphoedema?

Medical advice should be sought if unexplained or persistent swelling develops, particularly if it is increasing or affecting daily activities. Early assessment can help establish the cause and allow appropriate management to begin.

Urgent medical advice is needed if the affected area suddenly becomes red, hot, painful or more swollen, particularly when accompanied by a fever or flu-like symptoms.
