Lung infarction or pulmonary infarction occurs when an artery to the lung becomes blocked and part of the lung dies. It is most often caused by a pulmonary embolism.
Because of the dual blood supply to the lungs from both the bronchial circulation and the pulmonary circulation, this tissue is more resistant to infarction. An occlusion of the bronchial circulation does not cause infarction, but it can still occur in pulmonary embolism when the pulmonary circulation is blocked and the bronchial circulation cannot fully compensate for it.
