Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
Atherosclerosis in the aorta and other large blood vessels is a common risk factor, [2] both for thromboembolism and cholesterol embolism. The legs and feet are major impact sites for these types. [2] Thus, risk factors for atherosclerosis are risk factors for arterial embolisation as well: advanced age [1] cigarette smoking [1] [2]
The condition is often associated with thickening of the aortic wall, and can be differentiated from similar conditions (atherosclerotic plaque and a thrombus) through the use of computed tomography and magnetic resonance imaging, though the latter is superior. [2]
Starved for oxygen and nutrients, elastic fibers become patchy and smooth muscle cells die. If the disease progresses, syphilitic aortitis leads to an aortic aneurysm. Overall, tertiary syphilis is a rare cause of aortic aneurysms. [3] Syphilitic aortitis has become rare in the developed world with the advent of penicillin treatments after ...
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 ...
deep vein thrombosis (DVT) [3] [4] [5] BD71, pulmonary embolism (PE) [3] [4] [5] BB00. VTE is a common cardiovascular disorder with significant morbidity and mortality. [3] [4] [5] VTE can present with various symptoms, such as painful leg swelling, chest pain, dyspnea, hemoptysis, syncope, and even death, depending on the location and extent ...
A thrombus may become detached and enter circulation as an embolus, finally lodging in and completely obstructing a blood vessel, which unless treated very quickly will lead to tissue necrosis (an infarction) in the area past the occlusion. Venous thrombosis can lead to pulmonary embolism when the migrated embolus becomes lodged in the lung.
Aortitis is the inflammation of the aortic wall. The disorder is potentially life-threatening and rare. It is reported that there are only 1–3 new cases of aortitis per year per million people in the United States and Europe. [1] Aortitis is most common in people 10 to 40 years of age. [1]
