Definition (MSHCZE) Zánětlivé onemocnění cév, zejm. tepen, nejč. v rámci autoimunního, systémového či revmatického onemocnění. Stěna cév je poškozena zánětem, infiltrována leukocyty (neutrofily při akutním, lymfocyty při chronickém zánětu), v některých případech obrovskými buňkami (velkobuněčná v). Může dojít k fibrinoidní nekróze, vzniku aneurysmat. Postižení je obv. segmentární, postižené úseky se střídají s normálními. Poškození cévy může vést ke krvácení či ischemizaci oblasti (části orgánu). Klinické projevy dále obv. zahrnují zánětlivé příznaky a orgánová poškození. V. tvoří i podstatu mnoha projevů systémových chorob např. SLE. V léčbě v. se často uplatňují kortikoidy a imunosuprese. (cit. Velký lékařský slovník online, 2012 http://lekarske.slovniky.cz/ )
Definition (MEDLINEPLUS)

Vasculitis is an inflammation of the blood vessels. It happens when the body's immune system attacks the blood vessel by mistake. It can happen because of an infection, a medicine, or another disease. The cause is often unknown.

Vasculitis can affect arteries, veins and capillaries. Arteries are vessels that carry blood from the heart to the body's organs. Veins are the vessels that carry blood back to the heart. Capillaries are tiny blood vessels that connect the small arteries and veins.

When a blood vessel becomes inflamed, it can

  • Narrow, making it more difficult for blood to get through
  • Close off completely so that blood can't get through
  • Stretch and weaken so much that it bulges. The bulge is called an aneurysm. If it bursts, it can cause dangerous bleeding inside the body.

Symptoms of vasculitis can vary, but usually include fever, swelling and a general sense of feeling ill. The main goal of treatment is to stop the inflammation. Steroids and other medicines to stop inflammation are often helpful.

Definition (NCI) An inflammatory process involving the wall of the vessels (large, medium, or small-sized vessels). The inflammatory process may cause necrosis or formation of granulomas in the vascular wall. It may be the result of an autoimmune disorder, infection, or malignancy. Representative examples include polyarteritis nodosa, temporal arteritis, Wegener's granulomatosis, Kawasaki disease, Takayasu arteritis, and Henoch-Schonlein purpura.
Definition (NCI_CTCAE) A disorder characterized by inflammation involving the wall of a vessel.
Definition (CSP) inflammation of a blood vessel.
Definition (MSH) Inflammation of any one of the blood vessels, including the ARTERIES; VEINS; and rest of the vasculature system in the body.
