Just last week the American Heart Association updated their page related to Peripheral Artery Disease (PAD).

One of the most common types of diseases afflicting blood vessels is deep vein disease. While varicose veins are the most common result of this type of disease, there are other, more serious complications that can arise if left untreated. Venous ulcers, for example, form when deep vein disease is not taken care of in a timely manner. These can cause permanent injury to the tissue of your legs and may create chronic, non-healing wounds.
