Basic Facts:
The body’s network of veins, the blood vessels that return blood low in oxygen to the heart, is called the venous system.
Venous disease can change the appearance of the skin on a person’s arms or legs and can also cause skin ulcers (sores), limb discomfort and swelling. Serious forms of venous disease can cause blood clots that can block blood flow.
Serious forms of venous disease can cause blood clots that can block blood flow in the veins. these clots can break off and travel through the veins to the lungs.
Common types of venous disease include varicose veins, superficial thrombophlebitis, 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.
What are the symptoms?
DVT. Many people with DVT have no symptoms. Symptoms that occur may include a painful or swollen leg or a swollen ankle. If a blood clot caused by DVT breaks free, it may travel to the patients lungs, call pulmonary embolism. Symptoms of pulmonary embolism may include:
- Chest pain;
- Shortness of breath;
- Painful breathing;
- Cough; or
- Fever.
Chronic venous insufficiency. Symptoms may include:
- Swelling;
- Reddish-brown skin discoloration near the ankle; and
- Skin ulcers.
Superficial thrombophlebitis. Symptoms may include:
- Sudden swelling of the leg;
- Redness of the leg; and
- Slight fever.
Varicose veins. Varicose veins may cause swelling or aching legs.
Diagnosis
DVT. To diagnose DVT, a physician may order one or more of the following:
- Ultrasound;
- Venogram; or
- MRI.
Chronic venous insufficiency. Tests to help a physician diagnose chronic venous insufficiency include duplex ultrasound and venogram.
Superficial thrombophlebitis. This condition is usually diagnosed by the hardness of a vein felt on physical manipulation of the leg.
Varicose veins. Varicose veins are diagnosed by physical manipulation of the leg and, in some cases, an ultrasound.
