Abstract：
Aims/Background Although electromyography has been extensively used in the diagnosis of neurological diseases, there is no comprehensive understanding of the electromyography manifestations of spinal dural arteriovenous fistula. Given the widespread use of electromyography in the diagnosis of neurological conditions, it is worthwhile to holistically analyse the electromyography findings of spinal dural arteriovenous fistula to differentiate it from neurological diseases that share similar clinical manifestations. The aim of this study is to evaluate whether electromyography can distinguish spinal dural arteriovenous fistula from longitudinally extensive transverse myelitis. Methods We holistically reviewed files of all patients who were diagnosed with spinal dural arteriovenous fistula or longitudinally extensive transverse myelitis at The First Medical Centre of PLA General Hospital from 1 January 2010 to 31 December 2020. We compared the symptomology, epidemiology, and imaging results of patients with spinal dural arteriovenous fistula and longitudinally extensive transverse myelitis, placing emphasis on their electromyography manifestations. Student\'s t test was used to analyse normally distributed data, while Chi-square test was used to compare classification statistics. Results Lesions of spinal dural arteriovenous fistula shown on images tend to appear at lower lumbar and sacral segments, whereas lesions of the cervical and upper thoracic segments are more characteristic of longitudinally extensive transverse myelitis. Spinal dural arteriovenous fistula patients and longitudinally extensive transverse myelitis patients overlap in terms of clinical manifestations. After comparison, the two groups of patients had different demographics (age, sex), onset mode, predisposing factors before onset, and electromyographic features. The electromyographic features of patients with spinal dural arteriovenous fistula were associated with neurogenic damage (p < 0.001). Conclusions In patients with spinal dural arteriovenous fistula, electromyography can help clinicians to identify early disease, avoid patient treatment delay, and eliminate unnecessary treatment.
摘要：
目的/背景虽然肌电图已广泛用于神经系统疾病的诊断，硬脑膜动静脉瘘的肌电图表现尚不全面。鉴于肌电图在神经系统疾病的诊断中的广泛使用，值得全面分析硬脑膜动静脉瘘的肌电图表现，以将其与具有相似临床表现的神经系统疾病区分开来。这项研究的目的是评估肌电图是否可以区分硬脑膜动静脉瘘和纵向广泛的横贯性脊髓炎。方法全面回顾2010年1月1日至2020年12月31日解放军总医院第一医疗中心诊断为硬脊膜动静脉瘘或纵向广泛性横行性脊髓炎的所有患者的资料。我们比较了症状学，流行病学,以及硬脊膜动静脉瘘和纵向广泛横贯性脊髓炎患者的影像学结果，强调他们的肌电图表现。采用学生t检验分析正态分布数据，而卡方检验用于比较分类统计量。结果影像显示的硬脊膜动静脉瘘病变倾向于出现在腰下段和骶骨段。而颈部和上胸段的病变更多的是纵向广泛的横贯性脊髓炎。硬脊膜动静脉瘘患者和纵向广泛横贯性脊髓炎患者在临床表现上重叠。经过比较,两组患者有不同的人口统计学(年龄，sex),起始模式,发病前的诱发因素，和肌电图特征。硬脊膜动静脉瘘患者的肌电图特征与神经源性损伤相关(p<0.001)。结论硬脊膜动静脉瘘患者,肌电图可以帮助临床医生识别早期疾病，避免患者治疗延误，消除不必要的治疗。
