Many problems that block blood vessels look like vasculitis, leading doctors to sometimes assume they are dealing with vasculitis. While vasculitis may involve both the arteries (the thick muscular vessels that carry blood away from the heart) and the veins (the thinner vessels without muscles that carry blood toward the heart), it is rare for both arteries and veins to be involved at the same time. It may, however, cause pain if the parts that are no longer receiving a blood supply die – a circumstance called "infarction.") (Note: Vasculopathy can also block blood vessels but it does not cause the fever, pain and local tenderness associated with vasculitis. Depending on where the blockage occurs, almost any organ in the body can be affected. If the blood vessels are close to the skin, characteristic rashes occur. When vasculitis interferes with circulation in any part of the body it causes local tenderness and pain. This makes blood stick to the inner wall to form a clot. Inflammation causes the vessel wall to swell. When a blood vessel becomes inflamed and narrowed, blood supply to that area can become partially or completely blocked, cutting off blood supply to the tissues beyond. Vasculitis is blood vessel inflammation that causes fever, pain, local tenderness and other evidence of blocked blood vessels. If your doctor says you have vasculitis, ask specifically what he/she means before you research it on the internet! ( Find a doctor at HSS who treats vasculitis.) What is vasculitis? But those statistics, when the word is used loosely, do not provide correct information about your specific situation, and most conclusions that follows those statistics are likely to be wrong. Unfortunately, even some doctors use the term vasculitis to mean "an autoimmune disease and blood vessel abnormality that I don't completely understand." That is, they use "vasculitis" very loosely as a general term for autoimmune disease.Īs a result, you may see statistics about vasculitis that are very frightening. Some people – even physicians, but especially writers on the internet – incorrectly use these words interchangeably. Although vasculitis is one type of vasculopathy, if there is no inflammation, it is not vasculitis. Vasculitis should not be confused with "vasculopathy," which simply means something is wrong with the blood vessels. Warning about misuse of the term "vasculitis" Vasculitis by the size of the blood vessel. ![]() Diseases in which vasculitis is the specific illness, rather than a complication of another disease.When is vasculitis an important complication of an autoimmune disease?.
