Reflex sympathetic dystrophy is believed to involve overactivity of the sympathetic nervous system and it is associated with a large number of causes, mainly with local trauma, nevertheless brachial plexitis (neuralgic amyotrophy) was reported in only four patients by previous authors. We describe a new case in this report. The reinnervation sprouting of somatic nerve fibres can have abnormal sodium channels which can acquire ectopic pacemaker activity which can be stimulated by sympathetic efferent impulses, in this way the reinnervation period after a severe plexitis can be associated with an increased risk of this complication. The neurologist must be aware of this association to guide the affected patient to a correct treatment.
反射性交感神经营养不良被认为与交感神经系统过度活跃有关，它有多种病因，主要与局部创伤有关，不过此前的作者仅报道过4例臂丛神经炎（神经性肌萎缩）患者。我们在本报告中描述了1例新病例。躯体神经纤维的再支配芽生可出现异常钠通道，这些钠通道可获得异位起搏活动，而交感传出冲动可刺激这种活动，因此严重臂丛神经炎后的再支配期可能会增加这种并发症的风险。神经科医生必须了解这种关联，以便指导患者接受正确治疗。
