Explain of Pulmonary Pathology

68.Lung, hemorrhagic infarct, gross

Large thromboemboli can cause death. Medium sized thrombomboli (blocking a pulmonary artery to a lobule or set of lobules) can produce the lesion seen here--a hemorrhagic pulmonary infarction, because the patient survives. The infarct is wedge-shaped and based on the pleura. These infarcts are hemorrhagic because, though the pulmonary artery carrying most of the blood and oxygen is cut off, the bronchial arteries from the systemic circulation (supplying about 1% of the blood to the lungs) is not cut off.
