What is Phlebitis?
Phlebitis is the inflammation of a vein, typically occurring in the legs. It can result from various factors, such as injury, infection, or irritation, and is often associated with blood clots. When a blood clot causes the inflammation, the condition is referred to as thrombophlebitis. Symptoms of phlebitis may include redness, swelling, warmth, and pain in the affected area. Phlebitis can be superficial, affecting veins near the skin’s surface, or deep, involving deeper veins, which may pose a greater risk of complications like deep vein thrombosis (DVT).

What is Phlebitis?
Phlebitis 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 or other parts of the body. 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, usually 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.
Types of phlebitis
Phlebitis can affect both superficial and deep veins.
Superficial phlebitis refers to the inflammation of a vein near the surface of your skin. It can result from a blood clot or from something causing irritation in a vein, such as an intravenous (IV) catheter.
This type of phlebitis usually isn’t serious, but it can lead to:
- infection of the surrounding skin
- wounds on the skin
- bloodstream infections
If a clot in the superficial vein is extensive enough and involves the area where the superficial vein and a deep vein come together, a DVT can develop.
Deep vein phlebitis refers to inflammation of a deeper, larger vein, such as those found in your legs. Deep vein phlebitis is more likely to be caused by a blood clot, which can have very serious consequences.
A blood clot may break off and travel to your lungs. This is called a pulmonary embolism (PE) and can be life threatening. It’s important to know the risk factors and symptoms of a DVT so you can seek prompt attention from a healthcare professional.
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 thrombophlebitis include the following:
- Prolonged inactivity – Staying in bed or sitting for many hours, as in a car or on an airplane, creating stagnant or slow flow of blood from the legs in a dependent position (This pooling of blood in the legs leads to thrombus formation.)
- Sedentary lifestyle – Not getting any exercise
- Obesity
- Smoking cigarettes
- Certain medical conditions, such as cancer or blood disorders, that increase the clotting potential of the blood
- Injury to your arms or legs
- Hormone replacement therapy or birth control pills
- Pregnancy
- Varicose veins
Symptoms
Inflammation is the body’s response to tissue damage. Symptoms that may occur in areas affected by superficial phlebitis include:
- tenderness
- redness, including long, thin lines along the vein’s path
- warm to the touch
- skin may feel hard
- itching and burning
- throbbing sensations
- swollen skin
- discomfort
- worsening symptoms when leg is lowered
- low grade fever if infection
Symptoms of acute superficial thrombophlebitis and DVT are similar to those of superficial phlebitis but more intense:
- more severe redness, warmth, swelling
- increased pain and discomfort
- occasionally discoloration can be more blue than red
- one leg more swollen than the other
- more feelings of aching, throbbing and leg heaviness
Who is at risk?
A number of factors can increase your risk of phlebitis. You may be more likely to experience phlebitis if you:
- have a personal or family history of blood clots
- have a blood clotting disorder, such as factor V Leiden thrombophilia
- take hormone therapy or birth control pills
- experience long periods of inactivity, which may be needed after surgery
- sit for long periods of time, such as during travel
- have certain cancers and cancer treatments
- are pregnant
- have overweight or obesity
- smoke
- misuse alcohol
- have varicose veins, which can increase your risk of superficial phlebitis
- are over age 60
Diagnosis
The diagnosis of phlebitis involves a combination of clinical assessment, medical history, and diagnostic tests. Here are the key steps involved in diagnosing phlebitis:
1. Physical Examination:
- Inspection and Palpation: The doctor will examine the affected area for signs like redness, swelling, warmth, tenderness, or a firm, cord-like vein, which are characteristic of phlebitis.
- Pain Assessment: The physician may ask about pain, especially whether it worsens when standing or walking.
2. Medical History:
- The healthcare provider will inquire about risk factors such as recent surgeries, prolonged immobilization, trauma to the area, use of intravenous (IV) lines, or history of varicose veins.
3. Ultrasound (Doppler Imaging):
- A venous ultrasound is the most commonly used diagnostic tool. It uses sound waves to create images of the veins and detect any blood clots or inflammation, especially in cases of deep vein thrombophlebitis.
4. Blood Tests:
- In cases where deep vein thrombosis (DVT) is suspected, a D-dimer test may be conducted to check for elevated levels of clot-dissolving substances in the blood.
- Other blood tests may be done to identify underlying conditions (e.g., infection or autoimmune disorders) that may have triggered the phlebitis.
5. Venography (Rarely Used):
- In rare cases, a venogram may be performed. This test involves injecting a contrast dye into the veins to visualize them on X-rays and look for abnormalities such as blood clots.
6. Additional Imaging (If Needed):
- In cases of suspected deep vein involvement or complications, other imaging studies like CT scans or MRI may be used to assess the veins.
The combination of these methods helps differentiate between superficial phlebitis (involving surface veins) and more serious conditions like deep vein thrombosis (DVT).
Does Phlebitis Need Treatment?
If there are any symptoms of phlebitis, it is important to get diagnosed promptly. Early intervention can prevent any blood clots from causing an embolism if DVT is present. Once diagnosed, the vascular doctor will recommend a treatment plan that will also address any underlying vascular conditions.
Treatment
Superficial phlebitis often improves within a few weeks using self-care measures. If phlebitis affects a deep vein or you’re at risk of developing DVT, your doctor may recommend additional treatments. These may include:
- Anticoagulant blood-thinning medications. Anticoagulants reduce your blood’s ability to clot. This can help prevent an existing clot from becoming larger and reduce the risk of additional clots. These medications can be injected or taken orally.
- Thrombolytic medications. Also called “clot busters,“ thrombolytics dissolve a clot. They’re typically used for more serious cases of DVT.
- Varicose vein treatment. If you have recurrent superficial phlebitis in varicose veins, your doctor may recommend treatment for your varicose veins. Options may include sclerotherapy, laser treatment, or surgical removal of varicose veins.
- Thrombectomy. This procedure may be performed if the DVT is very extensive and causes significant problems with blood return in your limb. A surgeon inserts a wire and catheter into the affected vein and either removes the clot, dissolves it with medications that break up the clot, such as tissue plasminogen activators, or performs a combination of both.
- Vena cava filter. Insertion of a filter into one of your major blood vessels, the vena cava, may be recommended if you have a DVT and are at high risk of a PE but can’t take blood thinners. This filter won’t prevent blood clots from forming, but it will prevent pieces of the clot from traveling to your lungs.
When to see a Doctor?
You should see a doctor for phlebitis if you experience any of the following:
1. Persistent or Worsening Symptoms:
- Pain, redness, warmth, or swelling that does not improve or worsens over time, especially around a vein.
2. Signs of Infection:
- Fever, chills, or pus draining from the affected area, which may indicate an infection, particularly if there was an IV or injection in the area.
3. Severe Pain or Discomfort:
- Severe pain or a hard, cord-like vein under the skin, which may suggest thrombophlebitis (phlebitis associated with a blood clot).
4. Difficulty Moving the Affected Limb:
- If pain or swelling makes it difficult to move or use the affected limb (e.g., difficulty walking due to leg phlebitis).
5. Swelling in the Leg or Arm:
- Swelling that spreads to a larger area or becomes severe could be a sign of a deeper vein problem (deep vein thrombosis, or DVT), which requires immediate attention.
6. Shortness of Breath or Chest Pain:
- If you experience sudden chest pain, difficulty breathing, coughing up blood, or a rapid heartbeat, seek emergency medical attention. These could be signs of a pulmonary embolism (PE), a life-threatening complication of deep vein thrombosis (DVT).
7. History of Blood Clots:
- If you have had previous episodes of blood clots or deep vein thrombosis, or if you have risk factors (such as recent surgery, long travel, or immobilization), see a doctor if you notice any symptoms of phlebitis.
8. Risk Factors:
- Individuals with risk factors such as varicose veins, prolonged immobility, recent surgery, cancer, or pregnancy should see a doctor for any signs of phlebitis to prevent complications.
