Systemic vasculitis
（重定向自Necrotizing vasculitis）
Systemic necrotizing vasculitis (SNV) is a type of vasculitis that presents with necrosis.
An example is giant cell arteritis.
ICD-10 uses the variant "necrotizing vasculopathy". ICD-9, while classifying these conditions together, doesn't use a dedicated phrase, instead calling them "polyarteritis nodosa and allied conditions".
