Arteriosclerosis obliterans is an occlusive arterial disease most prominently affecting the abdominal aorta and the small- and medium-sized arteries of the lower extremities, which may lead to absent dorsalis pedis, posterior tibial, and/or popliteal artery pulses.
Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
Arterial occlusion can be classified into three types based on etiology: embolism, thrombosis, and atherosclerosis. These three types of occlusion underlie various common conditions, including coronary artery disease , [ 4 ] peripheral artery disease , [ 5 ] and pulmonary embolism , [ 6 ] which may be prevented by lowering risk factors.
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 ]
Hardening of the arteries (atherosclerosis). Atherosclerosis occurs when fat and other substances build up on the lining of a blood vessel, increasing the risk of an aneurysm. Infection in the aorta . In rare cases, abdominal aortic aneurysm may be caused by an infection or inflammation that weakens a section of the aortic wall. [3]
Atherosclerosis is a developmental disease in the large arteries, defined by the accumulation of lipids, macrophages and fibrous materials in the intima. [1] When the endothelial cell of blood vessel is damaged, it loses the ability to regulate itself. [1] It results in inflammation as the macrophages irrupt the vessel wall. [1]
Progression of atherosclerosis. A fatty streak is the first grossly visible (visible to the naked eye) lesion in the development of atherosclerosis.It appears as an irregular yellow-white discoloration on the luminal surface of an artery.
