体感诱发电位与感觉神经动作电位对于臂丛神经(节前节后)损伤的诊断价值

PRACTICAL VALUE OF SEP AND SNAP IN THE DIAGNOSIS OF BRACHIAL PLEXUS (PREGANGLIONIC OR POSTGANGLIONIC) INJURY

本文报告4例臂丛神经损伤进行SEP,SNAP及手术的对比观察结果,臂丛神经损伤(节前/节后)与神经生理SEP和SNAP波幅降低或消失有关,提示:SEP与SNAP的共同应用对于臂丛神经损伤定位(节前/节后)有较高的应用价值。

SEP and SNAP were applied in four patients with brachial plexus nerve injury.The results were compared with operation finding.The amplitude of SEP and SNAP were disappeared or reduced and these ncurophysiology abnormolities were related to the in jured focus.The paper suggest SEP and SNAP were valuable for differential diagnosis between preganglionic and postganglionic brachial plexus nerve injury.
