Vascular Interventional Radiology Treatments for Lymphatic Disease

The body’s lymphatic system comprises a network of tiny vessels that regulate lymph (a clear fluid containing infection-fighting white blood cells). These tiny vessels connect lymph nodes located throughout the body. Lymph fluid helps with several important body functions, including the immune system and nutrition. Lymph is returned to the bloodstream.

Traditional imaging techniques such at CT or US do not adequately image the lymphatic system. To help, our interventional radiologists inject contrast agent into lymph nodes and follow to better view the system. This is known as lymphangiography.

Lymphangiography helps diagnose lymphatic system disruptions, including leaks and other abnormalities. For example, lymphatic leaks may occur after surgery or trauma. As a result, lymph fluid may abnormally collect in the chest (chylothorax), abdomen (chylous ascites) or other parts of the body (lymphocele).

Treatment of the abnormal areas or damaged lymph structures may decrease collection or leak. Using image guidance, interventional radiologists inject embolization (blocking) materials or sclerosing (scarring) agents directly into lymph vessels or the abnormal collection.
