Explain of Atherosclerosis and Thrombosis

34.Hemorrhagic pulmonary infarction, gross

Occlusion of the main pulmonary arteries can kill the patient suddenly. Occlusion of small pulmonary arteries has no major immediate effect. Occlusion of a medium-sized branch of pulmonary artery can lead to a pulmonary infarction in a person with compromised cardiac or respiratory status. A pulmonary infarct is hemorrhagic because of the dual blood supply from the non-occluded bronchial arteries which continue to supply blood, but do not prevent the infarction.
