单器官血管炎

定义

单个器官中的动脉或静脉中的血管炎，没有任何特征表明它是系统性血管炎的一种有限表现。涉及器官和血管类型应包括在名称中（如皮肤SVV、睾丸动脉炎、中枢神经系统血管炎）。血管炎的分布可能是一个器官内单灶或多灶（弥漫）。最初诊断为SOV的一些患者将出现额外的疾病表现，这些表现有助于将该病例重新定义为系统性血管炎之一（例如皮肤动脉炎后来成为系统性结节性多动脉炎等）。Chappell Consument Consual Concement，2011年）

Vasculitis in arteries or veins of any size in a single organ that has no features that indicate that it is a limited expression of a systemic vasculitis. The involved organ and vessel type should be included in the name (e.g. cutaneous SVV, testicular arteritis, central nervous system vasculitis). Vasculitis distribution may be unifocal or multifocal (diffuse) within an organ. Some patients originally diagnosed with SOV will develop additional disease manifestations that warrant re-defining the case as one of the systemic vasculitides (e.g. cutaneous arteritis later becoming systemic polyarteritis nodosa, etc.).
