Surgical Management of Lymphedema.

Lymphedema is a chronic debilitating disease in which impaired drainage of lymphatic fluid causes accumulation of fluid in the soft tissues resulting in a swollen heavy limb. This ultimately leads to severe fibrosis, recurrent infections, non-healing wounds, and a poorly functioning limb that negatively affects a patient's quality of life. Primary lymphedema is due to abnormal development of the lymphatic system and patients can present with lymphedema at birth or later in life. Secondary lymphedema is caused by damage to the lymphatic system from infection, surgery to treat malignancies, trauma, and obesity. In the past, the only treatment was controlling the swelling to prevent progression of the disease by lymphatic therapy and various types of compression which is still currently the first line treatment. Advances in supermicrosurgery (connecting vessels less than 0.8 mm) have made way for surgical treatment options for lymphedema, including lymphovenous bypass and vascularized lymph node transplant. These new surgical treatment options combined with lymphatic therapy and compression have led to better results and improved patient's quality of life. After reading this article, the participant should be familiar with diagnosis, imaging, and surgical treatment of lymphedema.
