M31.9: Necrotizing vasculopathy, unspecified

Blood vessels transport the blood from the heart to the different tissues and organs in the body, and back again. In so doing, they provide the tissue and organs with oxygen and nutrients, and remove waste substances. When blood vessels get inflamed, they can become narrow. As a result, less blood may be supplied to certain tissues and organs. The tissue and organs can get damaged as a result. This can affect the skin, for example.
