Phlebolymphedema is a condition of mixed venous and lymphatic insufficiency. It is usually not recognized and it is usually not treated. The lymphatic and venous systems are intimately interrelated. In the presence of venous hypertension, which is characteristic of most venous disorders, the increase in lymphatic flow becomes much greater than the lymph transport capacity. The diagnosis of phlebolymphedema is based on a detailed history and physical examination. Patients with phlebolymphedema have skin changes of venous insufficiency, which are easy to recognize. Treatment for chronic phlebolymphedema consists of treating the venous abnormality and watching regression of the lymphatic problem.
