What is the medical term for a blood clot that travels to the lung?

The medical term for a blood clot that travels to the lung is pulmonary embolism (PE). This condition occurs when a clot, often originating from a deep vein in the legs (commonly associated with deep vein thrombosis), dislodges and travels through the bloodstream to the lungs. Once it reaches the pulmonary arteries, it can obstruct blood flow, leading to serious complications such as difficulty in breathing, chest pain, or even death, if not treated promptly.

Understanding the nature of a pulmonary embolism is crucial, particularly in the context of recognizing its risk factors, symptoms, and potential treatment options. In emergency situations, quick diagnosis and intervention are critical, as PE can rapidly become life-threatening. This makes awareness of its classification and implications important for both medical personnel and emergency responders.
