What is Superficial Thrombophlebitis?
Superficial thrombophlebitis (ST), also known as superficial phlebitis, is an inflammation in a vein near the skin’s surface. This inflammation happens when a blood clot forms in a vein, usually in the arms or legs.
In most instances, superficial thrombophlebitis isn’t severe. However, the condition can progress and develop into serious complications like deep vein thrombosis (DVT). Untreated DVT can increase the risk of stroke and other venous diseases.
Is Superficial Vein Thrombosis the Same as Superficial Thrombophlebitis?
The terms superficial thrombophlebitis and superficial vein thrombosis (or superficial venous thrombosis) are often used interchangeably, but there’s a subtle distinction.
- Superficial vein thrombosis (SVT) refers specifically to the presence of a blood clot in a vein close to the surface of the skin.
- Superficial thrombophlebitis (ST) describes both the clot and the accompanying inflammation of the vein wall.
In most cases, a superficial vein clot causes inflammation, so the two conditions typically occur together. However, understanding this distinction can help clarify medical terminology and treatment approaches.
Signs and Symptoms of Superficial Thrombophlebitis
Superficial thrombophlebitis is most common in the legs but can sometimes develop in other areas of the body, such as the neck or arms, due to the location of blood vessels.
Symptoms may include:
- Tenderness, pain, and warmth of the affected area
- Redness and swelling of the affected area
- Changes to skin color around the affected vein
- Changes to the texture of the skin around the vein
- Hardening of the vein
- Swelling along the affected vein
What Causes Superficial Thrombophlebitis?
Several factors can cause or contribute to the development of superficial thrombophlebitis. These include:
- Varicose veins
- An injection or IV into the vein
- Vein injury
- Long periods of inactivity, such as sitting or bed rest
- Blood clotting disorders
- Autoimmune conditions that involve the veins
- Certain cancers
- Medications that increase clotting risk
Who’s at Risk for Superficial Thrombophlebitis?
Superficial thrombophlebitis is associated with a few known risk factors, including:
- Obesity
- Smoking
- Pregnancy
- Being over the age of 60
- Hormone therapy
- Clotting disorders
Regular checkups can help prevent superficial thrombophlebitis and its potential complications. If you are at risk for developing a blood clot, superficial vein thrombophlebitis, or varicose veins, schedule an appointment with a vein specialist for a proper diagnosis.

Is Superficial Thrombophlebitis Dangerous?
Superficial thrombophlebitis is a type of blood clot that forms in veins near the skin’s surface. It’s generally less dangerous than deep vein thrombosis (DVT) and is rarely life‑threatening. However, if left untreated, the clot can sometimes extend into deeper veins where the superficial and deep systems connect, increasing the risk of more serious complications. In rare cases, can also occur.
Understanding Blood Clots and Your Health
Superficial thrombophlebitis is just one type of blood clot. Blood clots can develop in different parts of the body, and while some are minor, others—like those that form in deep veins or travel to the lungs—can be life‑threatening. Knowing the signs, potential risks, and when to seek care can make a major difference in protecting your health.
Superficial Thrombophlebitis vs. Deep Vein Thrombosis (DVT)
Superficial thrombophlebitis (ST) and deep vein thrombosis (DVT) both cause inflammation in the veins; however, there are differences between them, including the location of the affected veins, severity, and potential complications.
| Superficial Thrombophlebitis (ST) | Deep Vein Thrombosis (DVT) | |
| Location | Veins just beneath the skin’s surface | Deeper veins, usually in the legs |
| Severity | Generally not life‑threatening | Can be life‑threatening if untreated |
| Key Risk | Local discomfort, rare spread to deeper veins | A clot may break loose and cause a pulmonary embolism |
| Common Symptoms |

How Long Does Superficial Thrombophlebitis Last?
Superficial thrombophlebitis often resolves within a few weeks, but recovery can vary depending on the severity of the condition, the underlying cause, the presence of complications, and individual health factors, such as a previous history of blood clots or other underlying conditions.
How Long Do Superficial Blood Clots Last?
The blood clot that causes superficial thrombophlebitis typically dissolves on its own over several days to a few weeks. However, the timeline can vary depending on your risk factors, whether you’re receiving treatment, and whether complications like infection or clot extension occur.
How Is Superficial Thrombophlebitis Treated?
Superficial thrombophlebitis can go away on its own without intervention; however, it’s still important to consult a vein specialist for a proper diagnosis to ensure you receive the right treatment plan for lasting symptom relief and to help rule out more serious concerns.
Short-Term Symptom Relief
While waiting to see a specialist, some at-home remedies may temporarily ease pain and limit progression:
- Anti-inflammatory creams and gels: These products can help reduce swelling and alleviate localized pain by decreasing inflammation in the affected area.
- Compression therapy: Compression stockings can help increase circulation and reduce leg swelling.
- Leg elevation: Soothes pain and helps reduce inflammation.
Long-Term Treatment for Superficial Venous Thrombosis
Treatment plans depend on the severity and location of the affected veins, as well as risk factors for deep vein thrombosis (DVT) or pulmonary embolism (PE). Some of the medical options available to manage superficial thrombophlebitis include:
- Anticoagulant therapy to reduce the risk of clot extension or migration.
- Minimally invasive vein procedures to address underlying vein disease and prevent recurrence:
- Endovenous Laser Vein Treatment (EVLT)
- ClariVein®
- Varithena
- Ultrasound-Guided Sclerotherapy (USGS)
- VenaSeal™
- Radiofrequency Ablation (RFA)
- Visual Sclerotherapy

Being proactive about your vein health and consulting a doctor can help ensure your vein condition doesn’t develop into something more severe. Take the first step toward lasting symptom relief by scheduling an appointment at USA Vein Clinics.
FAQs about Superficial Thrombophlebitis
Can Superficial Thrombophlebitis Go Away on Its Own?
Superficial thrombophlebitis sometimes goes away on its own and without complications. Even if symptoms improve, it’s still important to see a medical professional to rule out deeper vein issues.
How is Superficial Thrombophlebitis Different from Varicose Veins?
Superficial thrombophlebitis is different from varicose veins because it involves a blood clot and inflammation in a vein located near the skin’s surface, whereas varicose veins are enlarged, bulging veins caused by weakened or damaged valves. While the two conditions can occur together—since varicose veins can increase the risk of clot formation—they remain distinct health issues with different causes and treatment approaches.
Can Superficial Thrombophlebitis Cause a Stroke?
Superficial thrombophlebitis can cause a stroke if it leads to deep vein thrombosis (DVT) and a blood clot travels to the brain. This progression is serious and requires medical attention.
Can I Exercise with Superficial Thrombophlebitis?
You can exercise with superficial thrombophlebitis, but light activities are recommended, like walking, to improve circulation and reduce swelling. Avoid strenuous or high-impact exercises that could aggravate symptoms.
Can Superficial Thrombophlebitis Come Back?
Superficial vein thrombophlebitis can recur, especially in those who have previously experienced superficial thrombophlebitis or have varicose veins.
Can I Fly with Superficial Thrombophlebitis?
In most cases, it is considered safe to fly with superficial thrombophlebitis if symptoms are stable and appropriate precautions are taken, such as standing and stretching periodically and using compression stockings. However, when a clot is located near a deep vein or anticoagulation therapy has recently been initiated, air travel is often postponed—commonly for about two weeks—until the condition is stable. Always consult a healthcare provider before flying to ensure it’s safe based on your specific situation.
