A blood clot that breaks off and travels around the body until it enters a blood vessel too narrow for it to continue. The blockage of this blood vessel then causes damage downstream of the embolism due to lack of oxygen and nutrients getting to this tissue.
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).
The obstruction of a blood vessel by a foreign substance or a blood clot blocking the vessel. Those traveling and lodging in the brain cause strokes; if it lodges in the heart, it would cause a heart attack.
Air or gas bubbles in the arterial (artery: a vessel conveying blood from the heart) system caused by gas or air passing into the pulmonary (lung) veins after rupture of the alveoli (air cells of the lung).
The obstruction of a blood vessel by a foreign substance or a blood clot blocking the vessel. Something travels through the bloodstream, lodges in a vessel and plugs it. See the entire definition of Embolism
Sudden blocking of an artery by a clot or a bit of foreign material brought to the site by the bloodstream; usually a blood clot but may be a fat globule, air bubble, piece of tissue, or a clump of bacteria.
a migration of a fragment of tissue or a blood clot into an artery. Arteries divide into smaller and smaller arteries. When an embolus arrives at an artery that is too small for him, it stops and blocks the arterial circulation in that artery. Oxygen can no longer reach the tissues vascularized by that artery, and they become necrosed (infarction).
A blood clot that develops in one part of the body and travels to another. (See Pulmonary Embolism); Obstruction of a blood vessel by the impaction of a solid body (eg., thrombi, fat globules, tumor cells) or an air bubble.
an abnormal circulatory condition, in which the embolus (a foreign object, air or gas, bit of a tissue or tumor, or a piece of a thrombus [clot]) that circulates in the bloodstream until it becomes lodged in a vessel.
In medicine, an embolism occurs when an object (the embolus, plural emboli) migrates from one part of the body (through circulation) and cause(s) a blockage (occlusion) of a blood vessel in another part of the body.
