The meaning of phlebitis, an inflammation of the wall of a vein, is easy to remember if you speak Greek: It contains the word phleb (“vein”) and the suffix-itis (“inflammation”). A number of factors can lead to this condition, including physical trauma, cancer, an infection of the tissues near the vein, and a lack of circulation due to bed rest or hours of prolonged sitting during a long trip.

This inflammation, over time, can lead to a blood clot—a condition called thrombophlebitis. The severity of each case depends on where the clot is located. Most often, the clots occur in superficial veins, those right under the skin’s surface. This type of phlebitis, which can cause redness and tenderness, is rarely serious and usually resolves on its own. Obesity, varicose veins, and blood clotting diseases increase the risk of this condition.

A red, swollen, painful leg can signal deep vein thrombosis. Deep vein thrombosis occurs when a larger clot clogs a vein deeper in the leg. This raises the risk of all or part of the clot breaking off and traveling to different areas of the body, causing an embolism. When an embolism blocks a vein draining to the lungs, it can result in a life-threatening pulmonary embolism.

To diagnose phlebitis, physicians usually perform an ultrasound with Doppler flow or an MRI to examine the veins. Wearing support hose to improve blood circulation and taking anticlotting drugs may be recommended. In more serious situations, a surgically inserted bypass or vein filter may be necessary.

ADDITIONAL FACTS

  1. The word thrombo means “clot.”
  2. Experts recommend that people with superficial phlebitis put their feet up to improve circulation.
  3. Moving your feet, wiggling your toes, and avoiding prolonged sitting can help prevent clots from forming in your leg veins.
