The dermatomal somatosensory evoked potential from the lumbo-sacral dermatomes was recorded from 21 patients with radiographically and surgically (20) proven lumbo-sacral root compression due to prolapsed intervertebral disc or canal stenosis. The potential was abnormal in 19 of the 20 surgically proven cases. The dermatomal somatosensory evoked potential is as accurate as myelography for diagnosis but has the advantage of being non-invasive and repeatable. It provides useful additional diagnostic and pathophysiological information about lumbo-sacral root compression.
对21例经影像学和手术(20例)证实因椎间盘突出或椎管狭窄导致腰骶神经根受压的患者,记录其腰骶皮节的皮节体感诱发电位。在20例经手术证实的病例中,19例诱发电位异常。皮节体感诱发电位在诊断方面与脊髓造影一样准确,但具有非侵入性和可重复性的优点。它为腰骶神经根受压提供了有用的额外诊断和病理生理信息。
