摘　　要：背景:胸廓出口综合征可因受压的结构不同分为神经型和血管型。神经型具有典型的临床症状、体征、放射学证据和肌电图改变。因此,关于电生理检测对胸廓出口综合征患者神经压迫症状的评估具有广泛的临床应用前景。目的:探讨电生理检测对胸廓出口综合征的诊断意义。设计:以患者为研究对象,采用完全随机方式,标准对照。单位:一所市级医院的电生理科。对象:收集1998-04/2002-07大连市中心医院神经内外科、手外科及门诊确诊为胸廓出口综合征的患者20例,男5例,女15例,年龄31～67岁,平均46.0岁,病程2～7年,平均4.5年。方法:采用丹麦产keypoint肌电诱发电位仪检测正中神经、尺神经、前臂内、外侧皮神经、肩胛上神经、腋神经、肌皮神经、桡神经传导速度、波幅及相应肌肉针电极肌电图。主要观察指标:神经电生理检测结果。结果:各干受压型表现为相应干所支配神经跨腋段感觉、运动神经传导速度减慢、波幅降低及相应肌肉失神经改变。结论:神经电生理检查对胸廓出口综合征诊断具有重要价值。BACKGROUND:Thoracic outlet syndrome can be divided into nervous system type and vascular type according to different compressed structure.Nervous system type has typical clinic manifestations, physical signs,radiological evidence and electromyogram variation. So,there is wide prospect for clinic application about evaluation of compression of nerve in patients with thoracic outlet syndrome by electrophysiological examination.OBJECTIVE:To study diagnostic significance of electrophysiological examination to thoracic outlet syndrome.DESIGN:A completed and randomized research based on patients.SETTING:An electrophysiological department in a municipal hospital.PARTICIPANTS:Twenty patients diagnosed as thoracic outlet syndrome were collected in Neurology and Neurosurgery Department, Hand Surgery Department and Clinic of Dalian Central Hospital from April 1998 to July 2002,in which there were 5 males and 15 females,aged 31- 67,average 46.0 years,with course of 2- 7 years, average 4.5 years.METHODS:Nerve conduction velocity,wave amplitude and corresponding muscular needle electrode electromyogram(EMG) of median nerve,ulnar nerve, interior and exterior cutaneous nerve in forearm,suprascapular nerve, axillary nerve,musculocutaneous nerve,radial nerve were tested by keypoint myoelectricity evoked potential equipment made in Denmark.MAIN OUTCOME MEASURES:The results of nerve electrophysiological examination.RESULTS:The type of compression of nerve trunk manifested as slower sensory and motor conduction velocity of nerve dominated by corresponding trunk across axillary section,lower wave amplitude and loss of nerve of corresponding muscle.CONCLUSION:Nerve electrophysiological examination is of important significance to diagnose thoracic outlet syndrome.
