Which major complication can arise from phlebitis?

Phlebitis, which is inflammation of a vein, particularly in the context of intravenous therapy, can lead to serious complications due to the potential for clot formation in the affected vein. One of the significant complications arising from phlebitis is the development of a thrombus, or a blood clot, in the vein. If this clot dislodges, it can travel through the bloodstream and potentially reach the lungs, resulting in a pulmonary embolism.

Pulmonary embolism is a major concern because it can block blood flow to the lungs, leading to respiratory distress, decreased oxygen levels, and serious cardiovascular complications. Recognizing the risk of pulmonary embolism is crucial for monitoring patients who have experienced phlebitis, as timely intervention can be critical for preventing this life-threatening condition.

Regarding the other options, deep vein thrombosis is indeed related and could be a complication of phlebitis, but the immediate risk that highlights the potential severity is the subsequent pulmonary embolism. Hip fractures and cerebral hemorrhages are not directly associated with phlebitis or its complications.
