Lymphoedema is a long-term condition in which lymph fluid does not drain normally, causing persistent swelling, heaviness, discomfort, skin changes and sometimes repeated infections such as cellulitis. It often affects an arm or leg after cancer treatment, surgery, radiotherapy or lymph node removal, although some people are born with a lymphatic system that does not work properly.

What is lymph node transfer?

Lymph node transfer, also called vascularised lymph node transfer, is a microsurgical operation designed to improve lymph drainage in selected patients with lymphoedema. The surgeon removes a small piece of tissue containing lymph nodes and their blood supply from one part of the body, such as the abdomen, groin, neck or armpit, and transfers it to the swollen area. The tissue is reconnected to tiny blood vessels so that it survives in its new position.

How does it work?

The aim is to restore or improve lymphatic drainage. The transferred lymph nodes may act like a “pump” or drainage hub, helping collect lymph fluid and return it to the circulation. They may also encourage the growth of new lymphatic channels over time. Because this process is gradual, improvement is usually measured over months rather than days or weeks.

Who might be suitable?

Lymph node transfer may be considered when lymphoedema remains troublesome despite good conservative treatment, including compression garments, skin care, exercise and specialist lymphoedema therapy. It is often used for secondary lymphoedema after cancer treatment. It may also be considered when lymphatic channels are too damaged for lymphovenous bypass, another microsurgical option that connects lymph vessels directly to small veins.

Careful assessment is essential. A specialist team may use lymphatic imaging, limb measurements and vascular tests to confirm the diagnosis, understand the stage of lymphoedema and check whether surgery is likely to help. Surgery is not suitable for everyone, particularly if swelling is mainly due to venous disease, uncontrolled medical problems or if compression and skin care cannot be maintained.

How effective is it?

Research suggests that lymph node transfer may reduce limb size, reduce episodes of cellulitis and improve quality of life for many carefully selected patients. Reviews of published studies commonly report meaningful reductions in limb circumference or volume, with some analyses finding average clinical improvement in the region of one-third to two-fifths. In cancer treatment-related lymphoedema, one review reported excess limb volume reductions of around 40% in the upper limb and 34% in the lower limb, as well as fewer cellulitis episodes.

However, results vary. Some patients notice a clear reduction in swelling and can use lighter compression, while others have modest improvement. Outcomes depend on factors such as the cause of lymphoedema, how long it has been present, the amount of fatty or fibrotic tissue in the limb, previous radiotherapy, the donor site used and the experience of the surgical team.

What does lymph node transfer not necessarily do?

Lymph node transfer is not a guaranteed cure. It does not necessarily remove all swelling, reverse every skin change, eliminate the need for compression garments or prevent cellulitis completely. It may not reduce limb size quickly and it cannot always correct swelling caused by established fatty enlargement or scarring. In more advanced lymphoedema, additional treatment such as liposuction or ongoing intensive compression may still be needed.

It is also important to understand that lymph node transfer does not replace daily self-management. Skin care, weight management where relevant, movement, exercise and compression remain central parts of treatment before and after surgery.

Risks and possible complications

As with any operation, lymph node transfer has risks. These can include bleeding, infection, wound healing problems, scarring, pain, numbness, problems with the blood supply to the transferred tissue and failure to achieve the desired improvement. There is also a small but important risk of causing swelling at the donor site, which is why modern surgical planning aims to choose and map donor lymph nodes carefully.

Recovery and follow-up

The operation is performed under general anaesthetic and may involve a short hospital stay. Recovery focuses on wound healing, protecting the transferred tissue and continuing lymphoedema therapy. Compression is usually continued after surgery, although the type and intensity may change over time. Because new lymphatic function develops gradually, follow-up measurements over several months are needed to judge the effect.

Questions to ask your specialist

• Is my swelling definitely lymphoedema and what stage is it?
• Am I more suitable for lymph node transfer, lymphovenous bypass, liposuction, conservative treatment or a combination?
• What improvement would be realistic in my case?
• Will I still need compression garments after surgery?
• Which donor site would be used, and how will the risk of donor-site lymphoedema be reduced?
• How many of these operations has the team performed and how are outcomes measured?

Key message

Lymph node transfer is a promising reconstructive option for selected people with lymphoedema. It can reduce swelling, infections and treatment burden, but it is not a cure and it does not work equally well for everyone. The best results come from careful patient selection, experienced microsurgical care and continued long-term lymphoedema management.
