Abstract

OBJECTIVES

Brachial plexopathy is clinically, and electrodiagnostically, a well-recognized entity. However, the involvement pattern of different parts of the plexus with different etiologies has not been well-characterized.

METHODS

A retrospective analysis of clinical and electrophysiologic findings in 203 patients with brachial plexopathies was performed.

RESULTS

Of 203 patients with brachial plexopathy, 182 (90%) were supraclavicular and 21 (10%) were infraclavicular. The following localizations were noted: upper trunk (UT) 27%; lower trunk (LT) 11%; UT + MT (middle trunk) 11%; LT + MT 7%; UT + MT + LT 25%; and UT + LT 1. Among the patients with brachial neuritis, 47% patients did not have pain before the onset and only 28% had a definable antecedent illness.

CONCLUSION

We report the largest to date reported case series of well-characterized brachial plexopathy patients. Upper trunk was the most frequently affected site of injury. In brachial neuritis, absence of pain and antecedent viral illness is more common than described in the literature.

摘要

目的

臂丛神经病变在临床和电诊断方面是一种已被充分认识的疾病。然而，不同病因导致的臂丛神经不同部位的受累模式尚未得到很好的描述。

方法

对203例臂丛神经病变患者的临床和电生理检查结果进行回顾性分析。

结果

203例臂丛神经病变患者中，182例（90%）为锁骨上型，21例（10%）为锁骨下型。观察到以下定位情况：上干（UT）27%；下干（LT）11%；UT + 中干（MT）11%；LT + MT 7%；UT + MT + LT 25%；以及UT + LT 1%。在臂丛神经炎患者中，47%的患者发病前无疼痛，仅有28%有明确的前驱疾病。
