arterial embolism

An arterial embolism occurs when a particle or substance, known as an embolus, obstructs blood flow in an artery. This embolus can be a dislodged blood clot, a fat globule from a bone fracture, tumor cells, bacteria, or even an air bubble. When an embolus blocks an artery, it can lead to a lack of blood supply to vital organs. For instance, an embolism in the brain can cause a stroke, while one in a coronary artery can result in a heart attack. Treatment often involves anticoagulant drugs to prevent further clot formation and, in some cases, surgical removal of the embolus.12
