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]
Thromboangiitis obliterans, also known as Buerger disease (English / ˈ b ɜːr ɡ ər /; German: [ˈbʏʁɡɐ]) or Winiwarter-Buerger disease, is a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet.
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]
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 ...
Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage.
The fibro-lipid (fibro-fatty) plaque is characterized by an accumulation of lipid-laden cells underneath the intima of the arteries, typically without narrowing the lumen due to compensatory expansion of the bounding muscular layer of the artery wall. Beneath the endothelium, there is a "fibrous cap" covering the atheromatous "core" of the plaque.
Evidence remains inconclusive about whether these risks outweigh the benefit of a coronary arterial stent. [3] [4] Inflammation may play a causal role in coronary artery disease and subsequent myocardial infarction due to coronary thrombosis. Increased levels of inflammation may lead to higher risk of clotting as well as an increased risk of ...
The endothelium, a smooth layer of the cell wall, is weakened and the artery-lining cells are injured. Rough patches develop along the endothelium and may promote the accumulation of deposits known as plaque. These deposits gradually harden and become more noticeable over time, restricting the artery and impairing normal blood flow. Different ...
