Over the previous few weeks, we have looked at the condition known as vasculitis, in which the blood vessels become inflamed, leading to necrosis, hemorrhage, ischemia, and infarction. Vasculitis may either be caused by one of a number of identifiable conditions (including diseases of the connective tissue, malignancy, or a drug reaction) or can be idiopathic with no identifiable cause.

The true prevalence of vasculitis is poorly understood because epidemiological studies are difficult to perform. However, the condition is known to exist across all ages and all races, although some populations appear more susceptible than others.

Treatment of vasculitis should be dictated by the severity of the condition. Mild forms of vasculitis usually resolve spontaneously by avoiding exacerbating conditions and through rest and leg elevation. However, if the condition is allowed to progress, systemic treatment is usually required to prevent more serious complications.
