A pulmonary embolism (PE) occurs when an artery in the lungs becomes blocked. The blockage is usually caused by a blood clot that travels to the lungs from the legs, which is a result of deep vein thrombosis (DVT).

Occlusion of blood vessels of the lungs can lead to increased blood pressure in the lungs called pulmonary hypertension, and can result in heart failure. Pulmonary emboli can also decrease the amount of oxygen in the blood.
