What is a major complication associated with phlebitis?

Phlebitis is the inflammation of a vein, often occurring in the legs, and can lead to various complications. One significant complication associated with phlebitis is the development of a thrombus, or blood clot, within the inflamed vein. If this thrombus dislodges, it can travel through the bloodstream and potentially reach the lungs, resulting in a pulmonary embolism.

The risk of pulmonary embolism stems from the formation of deep vein thrombosis (DVT), which can occur as a result of phlebitis. When a clot breaks loose, it can obstruct blood flow in the pulmonary arteries, causing serious respiratory issues and other complications. This progression illustrates the importance of timely diagnosis and management of phlebitis to prevent further complications like a pulmonary embolism.

Other options, while they may have associations with vascular issues, do not directly stem from phlebitis in the same manner as pulmonary embolism does. Understanding the link between phlebitis and thrombus formation helps in recognizing the potential severity of this condition.
