- The body’s network of veins, the blood vessels that return blood low in oxygen to the heart, is referred to as the venous system.
- Venous disease, or problems with the body’s veins, can change the appearance of the skin on a person’s arms or legs and can also cause sores, limb discomfort and swelling. Serious forms of venous disease can cause blood clots that can block blood flow.
- Common types of venous disease include varicose veins, phlebitis, chronic venous insufficiency and deep vein thrombosis.
Venous diseases are problems or conditions with the body's veins. Problems affecting veins occur because of inflammation, blood clots, obstruction, or stretching. There are four types of venous diseases:
- Deep vein thrombosis (DVT);
- Chronic venous insufficiency;
- Superficial thrombophlebitis (also called phlebitis); and
- Varicose veins.
