    Phlebitis

    Phlebitis Overview

    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. 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 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 phlebitis include the following:

    Phlebitis Symptoms

    Superficial phlebitis

    There is usually a slow onset of a tender red area along the superficial veins on the skin. A long, thin red area may be seen as the inflammation follows a superficial vein. This area may feel hard, warm, and tender. The skin around the vein may be itchy and swollen. The area may begin to throb or burn.

    Symptoms may be worse when the leg is lowered, especially when first getting out of bed in the morning. A low-grade fever may occur. Sometimes phlebitis may occur where a peripheral intravenous line was started. The surrounding area may be sore and tender along the vein.
