Which condition is characterized by inflammation in the vein?

Phlebitis is characterized by the inflammation of a vein, often occurring in the superficial veins of the legs. This condition can manifest with symptoms such as redness, swelling, warmth, and pain along the affected vein. It can be caused by various factors, including injury to the vein wall, infection, or prolonged intravenous therapy.

Understanding phlebitis is crucial for healthcare professionals involved in vascular access and patient care, as it underlines the importance of monitoring insertion sites and recognizing signs of complications. It emphasizes the need for proper technique and care when placing intravenous catheters to minimize the risk of inflammation and other related disorders.

The other conditions listed do not primarily involve inflammation of the vein itself. Thrombosis refers to the formation of a blood clot within a blood vessel. Embolism describes the obstruction of a blood vessel by a foreign substance or blood clot that has traveled from another location. Fibrillation relates to an irregular and often rapid heart rate that can lead to inefficient blood pumping but is not associated with inflammation of veins.
