What is a major complication of Phlebitis?

Phlebitis, which is inflammation of a vein, particularly in the context of intravenous therapy, can lead to serious complications. A major concern associated with phlebitis is the potential for thrombus formation at the site of inflammation. If a thrombus develops, it can dislodge and enter the circulatory system, traveling to the lungs, where it may cause a pulmonary embolism. This condition can severely compromise respiratory function and significantly affect circulation, potentially leading to life-threatening scenarios.

This connection to thromboembolism is the reason why pulmonary embolism is recognized as a significant complication of phlebitis. Immediate identification and treatment of phlebitis, which may include anticoagulation in some cases, can help mitigate the risk of developing this serious complication.
