Embolization involves the selective occlusion of blood vessels by purposely introducing emboli, in other words deliberately blocking a blood vessel. Embolization is used to treat a wide variety of conditions affecting different organs of the human body. Embolization is commonly used to treat active arterial bleeding.
Individuals with arterial thrombosis or embolism often develop collateral circulation to compensate for the loss of arterial flow. However, it takes time for sufficient collateral circulation to develop, [ 1 ] making affected areas more vulnerable for sudden occlusion by embolisation than for e.g. gradual occlusion as in atherosclerosis .
The symptoms experienced in cholesterol embolism depend largely on the organ involved. Non-specific symptoms often described are fever, muscle ache and weight loss.Embolism to the legs causes a mottled appearance and purple discoloration of the toes, small infarcts and areas of gangrene due to tissue death that usually appear black, and areas of the skin that assume a marbled pattern known as ...
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, [ 3 ] because the clot follows the pulmonary artery carrying deoxygenated blood away from ...
Arterial thromboembolism (ATE) is a less common but more severe form of thromboembolism, which can affect various organs, such as the brain, heart, kidneys, limbs, and mesentery. ATE can cause life-threatening conditions, such as stroke, myocardial infarction, acute kidney injury, limb ischemia, and mesenteric ischemia.
Embolization: Placement of a metallic coil or embolic substance (gel-foam, poly-vinyl alcohol) to block blood through to a blood vessel, either to stop bleeding or decrease blood flow to a target organ or tissue.
