An ischemic stroke may be caused by a blood clot that occurs in the affected artery (thrombosis), a blood clot that traveled from another part of the body (embolism), or a blockage due to damage to the arterial wall (lacunar infarct).

An embolus is most often a piece of a thrombus that has broken free and is carried toward the brain by the bloodstream. Thrombus aka blood clot is always caused by constituents of blood such as cellular items, fibrins, and platelets. Thrombosis occurs when a thrombus, or blood clot, develops in a blood vessel and reduces the flow of blood through the vessel. Components such as platelets or fibrin usually form when the human organ is injured. Embolism can cause stroke and also pulmonary embolus. If embolism obstructs blood flow that conveys oxygen to brain, it will cause stroke. An embolism can form: As a blood clot in a heart with an arrhythmia In a large artery-Blood clot-Atherosclerotic plaque.

These conditions may present the same if the blocked vessel is the same, but thrombosis blocks a blood vessel at a narrowed site while embolism may block healthy vessels, as well. Most of the time, a thrombus occurs within an area of the brain damaged by atherosclerosis. Thrombus vs Embolus. This type of stroke is usually seen in older persons, especially those with high cholesterol and atherosclerosis (a buildup of fat and lipids inside the walls of blood vessels) or diabetes.

Regardless of its source, an embolus does its damage by getting stuck in a large artery or branch and blocking blood flow beyond that point. This type of clot is known as a thrombus. An embolus is often a small piece of a blood clot that breaks off (thromboembolus). Thrombus formation also occurs in places where blood flow is sluggish, enabling clotting factors to accumulate and giving platelets more opportunity to stick together. Presumably an embolus floats along with the flowing blood until it encounters a narrowing in an artery through which it cannot pass. Difference between thrombosis and embolism youtube. Dieser verschleppte Thrombus heißt dann Embolus und löst eine Embolieaus. Meist handelt es sich dabei um ein Blutgerinnsel (Thrombus).

An embolus is anything that travels through the blood vessels until it reaches a vessel that is too small to let it pass. Thrombus is located in the site of origination while embolus can be a piece of thrombus that breaks off from a thrombus. Remember that thrombus tends to form on the surfaces of plaques where the lining of the vessel has been damaged.
