—The blockage of a blood vessel by an embolus—something previously circulating in the blood (such as a blood clot, gas bubble, tissue, bacteria, bone marrow, cholesterol, fat, etc )
An embolism is a serious medical condition that occurs when an artery becomes blocked, usually by a blood clot. something such as a hard mass of blood or a small amount of air that blocks a tube carrying blood through the body (embolismus, from emballein; EMBLEM). Obstruction of blood flow by an embolus a substance (e.g., a blood clot, a fat globule from a crush injury, or a gas bubble) not normally present in the bloodstream. Obstruction of an artery to the brain may cause stroke. Pulmonary embolism (in the pulmonary artery or a branch) causes difficulty breathing, chest pain, and death of a section of lung tissue, with fever and rapid heartbeat. Embolism in a coronary artery can cause heart attack. See also thrombosis
The blocking of a blood vessel by a blood clot that has formed in one place, has traveled to another point in the circulatory system and has lodged at that point
An embolism is when an embolus - a traveling clot of blood, fat, air, or other substance - lodges in an artery and blocks the blood flow Pulmonary embolisms (clots in the pulmonary artery) are the most common An embolus which goes to the brain can cause a stroke
The cessation of blood flow through an artery due to a sudden blockage from a blood clot; this leads to a stroke when it occurs in the carotid arteries and to a heart attack when it occurs in the coronary arteries
An obstruction or occlusion of an artery by an embolus, that is by a blood clot, air bubble or other matter that has been transported by the blood stream
Intercalation; the insertion of days, months, or years, in an account of time, to produce regularity; as, the embolism of a lunar month in the Greek year
Obstruction of a blood vessel by an embolus, or foreign substance, that has been transported by the ciruculatory system The embolus may be a blood clot, an air bubble, a fat globule, a clump of bacteria, a tumor cell, a piece of foreign matter such as a bullet fragment or a portion of a parasite such as a tapeworm The result is an infarct, an area of dead tissue caused by obstruction of the flow of blood to the body cells in an area fed by no collateral system Infarction may damage the heart or the brain, causing heart failure or paralysis
A body in the circulation that obstructs blood flow There are a number of types of emboli, including thromboemboli (blood clots in the circulation), fat emboli (due, for example, to release of fat globules into the circulation from bone marrow as can occur in fractures accompanying traumatic accidents), and air emboli (due, for example, to faulty injection technique)
