The main symptom is pain in the affected areas, at rest and while walking (claudication). [1] The impaired circulation increases sensitivity to cold. Peripheral pulses are diminished or absent. There are color changes in the extremities.
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]
Obliterating endarteritis is severe proliferating endarteritis (inflammation of the intima or inner lining of an artery) [1] that results in an occlusion of the lumen of the artery. [2] Obliterating endarteritis can occur due to a variety of medical conditions such as a complication of radiation poisoning , [ 3 ] a late side effect of radiation ...
Takayasu's arteritis is a disease causing inflammation of arteries, including the subclavian artery. Inflammation leaves behind dense scar tissue, which can become stenotic and restrict blood flow. [4] SSS can be iatrogenic, meaning a complication or side effect of medical treatment, one example being the obstructive fibrosis or thrombosis ...
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.
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 ...
