Phlebitis

Phlebitis (fle-BYE-tis) means inflammation of a vein. Thrombophlebitis is due to one or more blood clots in a vein that cause inflammation. Thrombophlebitis usually occurs in leg veins, but it may occur in an arm or other parts of the body. The thrombus in the vein causes pain and irritation and may block blood flow in the veins. Phlebitis can occur in both the surface (superficial) or deep veins.

 

 

Superficial phlebitis affects veins on the skin surface. The condition is rarely serious and, with proper care, usually resolves rapidly. Sometimes people with superficial phlebitis also get deep vein thrombophlebitis, so a medical evaluation is necessary.

 

Deep vein thrombophlebitis affects the larger blood vessels, usually deep in the legs. Large blood clots can form, which may break off and travel to the lungs. This is a serious condition called pulmonary embolism.

 

Phlebitis Causes

 

Superficial phlebitis can be a complication due to a medical or surgical procedure.

 

 

Injury to a vein increases the risk of forming a blood clot. Sometimes clots occur without an injury. Some risk factors for thrombophlebitis include the following:

 

 

 

Prolonged inactivity – Staying in bed or sitting for many hours, as in a car or on an airplane, creating stagnant or slow flow of blood from the legs in a dependent position (This pooling of blood in the legs leads to thrombus formation.)

 

Sedentary lifestyle – Not getting any exercise

 

Obesity

 

Smoking cigarettes

 

Certain medical conditions, such as cancer or blood disorders, that increase the clotting potential of the blood

 

Injury to your arms or legs

 

Hormone replacement therapy or birth control pills

 

Pregnancy

 

Varicose veins
