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.
Specific symptoms: [8] Claudication of the jaw; Engorged, tender vessels; Specific symptoms usually develop in the advanced stages of temporal arteritis. [8] These symptoms can include damage to eyesight and sudden blindness in one or both eyes. [9] Polyarteritis nodosa of unknown mechanism can cause testicular pain.
Buerger's disease – inflammation and swelling in small blood vessels, causing the vessels to narrow or become blocked by blood clots. [18] Raynaud syndrome – a peripheral vascular disorder that causes constriction of the peripheral blood vessels in the fingers and toes when a person is cold or experiencing stress. [19]
People with coronary artery disease, or narrowing of the blood vessels supplying their heart, may develop symptoms such as: Chest pain that often gets worse with stress or physical activity ...
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 ...
More specific symptoms occur usually based off where in body the vasculitis is occurring, and which organ is supplied by that blood vessel. Reduced blood flow caused by vasculitis can cause organ ischemia which can happen in two ways. First, blood cells clump onto the exposed tissue factor and collagen on the inside of blood vessels forming ...
Neutrophils migrate from blood vessels to the infected tissue via chemotaxis, where they remove pathogens through phagocytosis and degranulation Inflammation is a process by which the body's white blood cells and substances they produce protect us from infection with foreign organisms, such as bacteria and viruses. The (phagocytes) white blood ...
The underlying mechanism involves inflammation of the small blood vessels that supply the walls of larger arteries. [4] This mainly affects arteries around the head and neck, though some in the chest may also be affected. [4] [8] Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal ...
