Arterial embolism

embolism is a sudden interruption of blood flow to an organ or body part due to an embolus adhering to the wall of an blocking the flow of blood, the major type of embolus being a blood clot (thromboembolism). Sometimes, embolism is classified as arterial embolism as well, in the sense that the clot follows the pulmonary artery carrying deoxygenated blood away from the heart. However, pulmonary embolism is generally classified as a form of embolism, because the embolus forms in veins. Arterial embolism is the major cause of infarction.
