Overview

Competent venous valves, intermittent leg muscle contraction and respiration is required to support normal venous blood return. When these fail, venous insufficiency and edema occur. Edema is caused by an accumulation of an excessive amount of watery fluid in the serous cavities, tissues or cells causing painless, non-reddened swelling.
