The terms "giant cell arteritis" and "temporal arteritis" are sometimes used interchangeably, because of the frequent involvement of the temporal artery. However, other large vessels such as the aortacan be involved.[44] Giant-cell arteritis is also known as "cranial arteritis" and "Horton's disease".[45] The name (giant cellarteritis) reflects ...
Polyarteritis nodosa (PAN) is a type of systemic necrotizing vasculitis that primarily affects arteries of medium size. While small vessels like arterioles, capillaries, and venules are not affected, small arteries can be. The disease spectrum varies from failure of multiple organs to involvement of a single organ.
AAION is due to temporal arteritis (also called giant-cell arteritis), an inflammatory disease of medium-sized blood vessels (Chapel-Hill-Conference) that occurs especially with advancing age. In contrast, NAION results from the coincidence of cardiovascular risk factors in a patient with "crowded" optic discs.
Arteritis. 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]
Giant cell arteritis: Giant cell arteritis can result in granulomatous inflammation within the central retinal artery and posterior ciliary arteries of eye, resulting in partial or complete occlusion, leading to decreased blood flow manifesting as amaurosis fugax. Commonly, amaurosis fugax caused by giant cell arteritis may be associated with ...
Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis (WG), [1][2][3][4][5] after the German physician Friedrich Wegener, is a rare long-term systemic disorder that involves the formation of granulomas and inflammation of blood vessels (vasculitis). It is an autoimmune disease and a form of vasculitis that affects ...
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.
Aortitis is most commonly seen in patients with syphilis, autoimmune vasculitis (giant cell arteritis, Takayasu's arteritis), polymyalgia rheumatica, and rheumatoid arthritis. [2] IgG4-related disease has more recently been identified as a cause of aortitis, and also as a cause of periaortitis (inflammation surrounding the aorta). [3]
