Phlebitis (or Venitis) is
inflammation
Inflammation (from la, inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, and is a protective response involving immune cells, blood vessels, and molec ...

Veins are blood vessels in humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated ...

Deep vein thrombosis (DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. A minority of DVTs occur in the arms. Symptoms can include pain, swelling, redness, and en ...

Signs and symptoms
* Localized
redness and swelling
* Pain or burning along the length of the vein
* Vein being hard and cord-like
There is usually a slow onset of a tender red area along the superficial veins on the skin. A long, thin red area may be seen as the inflammation follows a superficial vein. This area may feel hard, warm, and tender. The skin around the vein may be itchy and swollen. The area may begin to throb or burn. Symptoms may be worse when the leg is lowered, especially when first getting out of bed in the morning. A low-grade fever may occur. Sometimes phlebitis may occur where a peripheral intravenous line was started. The surrounding area may be sore and tender along the vein.
Cause
Phlebitis is typically caused by local trauma to a vein, usually from the insertion of an intravenous catheter. However, it can also occur due to a complication of connective tissue disorders such as lupus, or of pancreatic, breast, or ovarian cancers. Phlebitis can also result from certain medications and drugs that irritate the veins, such as
desomorphine
Desomorphine is a semi-synthetic opioid commercialized by Roche, with powerful, fast-acting effects, such as sedation and analgesia. It was first discovered and patented by a German team working for Knoll in 1920 but was not generally recogniz ...

Superficial phlebitis often presents as an early sign in
thromboangiitis obliterans (Buerger's disease), a vasculitis that affects small and medium-sized arteries and veins in distal extremities often associated with cigarette smoking.
Management
Treatment usually consists of
NSAID
Non-steroidal anti-inflammatory drugs (NSAID) are members of a Indication (medicine), therapeutic drug class which Analgesic, reduces pain, Anti-inflammatory, decreases inflammation, Antipyretic, decreases fever, and Antithrombotic, prevents blo ...

compression stockings or a

For acute infusion superficial thrombophlebitis, not enough evidence exists as of 2015 to determine treatment.
