[Advances in treatment of lymphedema with supraclavicular vascularized lymph node transfer].

ABSTRACT

Objective: To review the research progress of supraclavicular vascularized lymph node transfer (VLNT). Methods: The research literature related to supraclavicular VLNT at home and abroad in recent years was extensively reviewed, and the anatomy of supraclavicular lymph nodes, clinical applications, and complications of supraclavicular VLNT were summarized. Results: The supraclavicular lymph nodes are anatomically constant, located in the posterior cervical triangle zone, and the blood supply comes mainly from the transverse cervical artery. There are individual differences in the number of supraclavicular lymph nodes, and preoperative ultrasonography is helpful to clarify the number of lymph nodes. Clinical studies have shown that supraclavicular VLNT can relieve limb swelling, reduce the incidence of infection, and improve quality of life in patients with lymphedema. And the effectiveness of supraclavicular VLNT can be improved by combined with lymphovenous anastomosis, resection procedures, and liposuction. Conclusion: There are a large number of supraclavicular lymph nodes, with abundant blood supply. It has been proven to be effective for any period of lymphedema, and the combined treatment is more effective. The more clinical studies are needed to clarify the effectiveness of supraclavicular VLNT alone or in combination, as well as the surgical approach and timing of the combined treatment.
