Lymphedema, which mostly occurs in the extremities. Surgery, trauma, infectious diseases, parasites, etc. can be the cause. Treatment is generally difficult. Compression and baking treatments can be effective, but they have many drawbacks and are not a perfect solution. Many patients are either unwilling to undergo long-term conservative therapy or receive it with little success. Surgical procedures are another way to treat lymphedema. Traditional surgery uses a large excisional approach that is highly invasive and has a poor surgical appearance. A new treatment method is now available through lymph node transplantation to relieve pressure on the distal end of the edematous limb, with significant clinical results. The lymph node transplantation approach offers a new treatment option for patients who have suffered from lymphedema for a long time.
