Superficial Thrombophlebitis

What is superficial thrombophlebitis?

 

Superficial thrombophlebitis (ST, or SVT) is a condition in which a blood clot forms in a vein near the surface of the body.  Often it develops in varicose veins, usually in the leg, pelvis, or arm.

 

How does it occur?

 

ST occurs when a clot forms in a surface vein.  ST can occur after minor injury to a vein, for example, after a bruise or after you have had an IV (medicine or fluid given through a vein).  It can also occur after intense exercise.  ST can also occur in response to systemic medical or surgical diseases, or from a hypercoagulable state (blood clotting disorder).

 

What are the symptoms?

 

Symptoms of superficial thrombophlebitis may include:

            · tender cordlike vein that is very sensitive to pressure
            · redness and warmth in the area around the vein
            · swelling in the area around the vein.

 

How is it diagnosed?

 

Your health care provider will ask about your symptoms and examine you.  He or she will be able to determine if you have ST from the physical exam.  In most cases you may have special ultrasound or x-ray studies to check for clots in deeper veins.

 

How is it treated?

 

For treatment, your health care provider may recommend that you:

            · Take an anti-inflammatory drug, such as aspirin or ibuprofen.
            · Exercise (such as walking).
            · Put warm, moist compresses on the inflamed area (be careful to avoid burns).
            · Elevate the affected arm or leg above the level of your heart when you are lying
              down.

 

How long will the effects last?

 

With proper treatment, ST usually last 1 to 2 weeks.

 

How can I take care of myself?

 

Follow your health care provider’s instructions.
           

 

How can I help prevent ST?

 

Because ST usually results from injury, it is hard to prevent.
