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 ...
The definite diagnosis of vasculitis is established after a biopsy of involved organ or tissue, such as skin, sinuses, lung, nerve, brain, and kidney. The biopsy elucidates the pattern of blood vessel inflammation. Some types of vasculitis display leukocytoclasis, which is vascular damage caused by nuclear debris from infiltrating neutrophils. [37]
Cerebral vasculitis (sometimes the word angiitis is used instead of "vasculitis") is vasculitis (inflammation of the blood vessel wall) involving the brain and occasionally the spinal cord. [1] It affects all of the vessels: very small blood vessels ( capillaries ), medium-size blood vessels ( arterioles and venules ), or large blood vessels ...

Small vessel cutaneous vasculitis is a diagnosis of exclusion and requires ruling out systemic causes of the skin findings. [14] Skin biopsy (punch or excisional) is the most definitive diagnostic test and should be performed with 48 hours of appearance of the vasculitis. [ 6 ]
Cryoglobulinemic vasculitis is a form of inflammation affecting the blood vessels caused by the deposition of abnormal proteins called cryoglobulins. These immunoglobulin proteins are soluble at normal body temperatures, but become insoluble below 37 °C (98.6 °F) and subsequently may aggregate within smaller blood vessels.
However, overall serum complement levels are normal. On the basis of symptoms, it is possible to distinguish HSP from hypersensitivity vasculitis (HV). In a series comparing 85 HSP patients with 93 HV patients, five symptoms were found to be indicative of HSP: palpable purpura, abdominal angina , digestive tract hemorrhage (not due to ...
Diagnosing vascular disease can be complex due to the variety of symptoms vascular diseases can cause. Reviewing a patient's family history and conducting a physical examination are important steps in making a diagnosis. Physical exams may differ depending on the type of vascular disease suspected.
