classification
•Embolism can be classified based on where it enters the circulation, either in arteries or in veins. Arterial embolism are those that follow and, if not dissolved on the way, lodge in a more distal part of the systemic circulation.
•Sometimes, multiple classifications apply; for instance a pulmonary embolism is classified as an arterial embolism as well,in the sense that the clot follows the pulmonary artery carrying deoxygenated blood away from the heart.
Definition
•An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel.[1] The embolus may be a blood clot (thrombus), a fat globule (fat embolism), a bubble of air or other gas (gas embolism), or foreign material.
•An embolism can cause partial or total blockage of blood flow in the affected vessel.
• Such a blockage (a vascular occlusion) may affect a part of the body distant from the origin of the embolus.
• An embolism in which the embolus is a piece of thrombus is called a thromboembolism
