Thrombophlebitis is phlebitis (vein inflammation) related to a thrombus (blood clot). When it occurs repeatedly in different locations, it is known as "Thrombophlebitis migrans", "migrating thrombophlebitis" or Trousseau's syndrome.
Signs and symptoms
The following symptoms are often (but not always) associated with thrombophlebitis:
- pain in the part of the body affected
- skin redness or inflammation (not always present)
- swelling (edema) of the extremities (ankle and foot)
- palpable cord-like veins
- localized warmth and tenderness of the leg
Thrombophlebitis (another medical term is "White Leg") is related to a thrombus in a superficial vein. Risk factors include disorders related to increased tendency for blood clotting, injury to vein wall, and reduced speed of blood in the veins such as varices and prolonged immobility. Prolonged traveling by car or airplane may promote a blood clot leading to thrombophlebitis but this occurs relatively rarely. Specific disorders associated with thrombophlebitis include superficial thrombophlebitis (affects veins near the skin surface), deep venous thrombosis (affects deeper, larger veins), and pulmonary embolism. High estrogen states such as pregnancy, estrogen replacement therapy, or oral contraceptives are associated with an increased risk of thrombophlebitis. Those with familial clotting disorders such as Protein S deficiency, Protein C deficiency, or Factor V Leiden deficiency are also at increased risk of thrombophlebitis. Thrombophlebitis can be found in people with vasculitis including Behçet's disease. Thrombophlebitis migrans can be a sign of malignancies such as pancreatic carcinoma (Trousseau sign of malignancy).
The health care provider makes the diagnosis primarily based on the appearance of the affected area. Frequent checks of the pulse, blood pressure, temperature, skin condition, and circulation may be required.
If the cause is not readily identifiable, tests may be performed to determine the cause, including the following:
Routine changing of intravenous (IV) lines helps to prevent phlebitis related to IV lines. See the specific disorders associated with thrombophlebitis for other preventive measures.
For more specific recommendations, see the particular condition. In general, treatment may include the following:
- analgesics (pain medications)
- anticoagulants e.g. warfarin or heparin to prevent new clot formation
- thrombolytics to dissolve an existing clot such as intravenous streptokinase.
- nonsteroidal anti-inflammatory medications (NSAIDS) such as ibuprofen to reduce pain and inflammation
- Support stockings and wraps to reduce discomfort
The patient may be advised to do the following:
- Elevate the affected area to reduce swelling.
- Keep pressure off of the area to reduce pain and decrease the risk of further damage.
- Surgical removal, stripping, or bypass of the vein is rarely needed but may be recommended in some situations.
Thrombophlebitis and other forms of phlebitis usually respond to prompt medical treatment.
Not all superficial thrombophlebitis is benign  Complications are rare, but when they occur they can be serious. The most serious complication occurs when the superficial blood clot is associated with a deeper venous thrombosis; this can then dislodge, traveling through the heart and occluding the dense capillary network of the lungs; this is a pulmonary embolism which can be potentially life-threatening.
