Causes
This condition is caused by a blood clot forming in the vein.
Risk Factors
Superficial thrombophlebitis is more common in women. The risk is higher in those aged 60 years or more. Other things that raise the risk are:
- History of vein problems or blood clotting problems
- Long term bed rest or sitting
- Obesity
- Pregnancy
- An IV, injury, or recent surgery
- Certain cancers
- Birth control pills or hormone replacement therapy
- Immune system problems
Symptoms
Symptoms of superficial thrombophlebitis may be:
- A vein that looks like a cord
- Redness, warmth, and tenderness around the vein
- Swelling around the vein
It can lead to problems such as:
- Deep vein thrombosis—a blood clot in the deeper veins that blocks blood flow
- Pulmonary embolism—the blood clot breaks free and gets lodged in the lungs
Diagnosis
The doctor will ask about symptoms and health history. A physical exam will be done.
Imaging tests will be done to diagnose superficial thrombophlebitis. They may include:
Treatment
Superficial thrombophlebitis often goes away on its own in a few weeks. If needed, treatment may involve:
- Wearing compression stockings—to improve blood flow in legs
- Exercise
- Medicines such as:
- NSAIDs like ibuprofen—to ease pain and inflammation
- Blood thinners
- Procedures to remove the blood clot—if the problem gets worse or returns
Prevention
The risk of having this problem may be lowered by:
- Walking around the cabin every hour when flying
- Pulling over every hour or so and stretching when driving long distances
