The term vasculitis is defined as inflammation of the blood vessel wall. Small-vessel vasculitides affect post-capillary venules, mostly in the skin. Defining the different types of small-vessel vasculitides is important as they may be associated with systemic manifestations, may require additional patient evaluation and may require more than only supportive care. Evaluation of a patient with suspected small-vessel vasculitis requires skin biopsy, evaluation of the extent of the disease, and an attempt to define an etiology. Management is based on providing supportive care, treating any underlying condition, avoiding any triggers, and treating based on severity of skin lesions and systemic involvement.
血管炎的定义为血管壁的炎症。小血管血管炎影响小静脉后微静脉，主要发生在皮肤。定义不同类型的小血管血管炎很重要，因为它们可能与全身表现有关，可能需要额外的患者评估，并且可能不仅需要支持性护理。疑似小血管血管炎患者的评估需要皮肤活检、疾病程度评估，并尝试确定病因。治疗基于提供支持性护理、治疗任何基础疾病、避免任何诱因以及根据皮肤损伤和全身受累的严重程度进行治疗。
