What does phlebitis increase the risk of?

Phlebitis, which is the inflammation of a vein, commonly occurs following intravenous therapy or the placement of IV catheters. This condition can lead to complications, one of which is an increased risk of pulmonary embolism. When a thrombus (blood clot) forms at the site of phlebitis, there is a potential for this clot to dislodge and travel to the lungs, where it can cause a pulmonary embolism. This complication is particularly concerning because it can be life-threatening.

Understanding the implications of phlebitis is vital in clinical settings. Monitoring patients for signs of venous inflammation is crucial, as early intervention may help to prevent the formation of clots and subsequently reduce the risk of pulmonary emboli. While phlebitis can indeed lead to other complications like infections or affect neighboring tissues, the direct and significant risk posed to the pulmonary circulation is a key factor that emphasizes the importance of recognizing and managing phlebitis promptly.
