Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
Degenerative changes that occur with age in the walls of large elastic arteries are thought to contribute to increased stiffening over time, including the disruption of lamellar elastin structures within the wall, possibly due to repeated cycles of mechanical stress; inflammation; [7] changes in arterial collagen proteins, partially as a ...
Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein , it can, in some cases, cause deep vein thrombosis .
Angiopathy is the generic term for a disease of the blood vessels (arteries, veins, and capillaries). [1] This also refers to the condition of damage or rupture of small blood vessels. The best known and most prevalent angiopathy is diabetic angiopathy , a common complication of chronic diabetes .
Arteritis is a vascular disorder characterized by inflammation of the walls of arteries, [1] usually as a result of infection or autoimmune responses. Arteritis, a complex disorder, is still not entirely understood. [2] Arteritis may be distinguished by its different types, based on the organ systems affected by the disease. [2]
Necrotizing vasculitis, also called systemic necrotizing vasculitis, [1] is a general term for the inflammation of veins and arteries that develops into necrosis and narrows the vessels. [ 2 ] Tumors , medications, allergic reactions , and infectious organisms are some of the recognized triggers for these conditions, even though the precise ...
The most common type is coronary artery disease, in which plaque builds up in the arteries and blocks blood flow to the heart, potentially leading to heart attacks or heart failure.
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. [9]
