腕管综合征的临床与神经电生理分析

目的 探讨腕管综合征（CTS）的临床特点和神经电生理检测对CTS的诊断价值.方法 回顾性分析33例CTS的临床特征和神经电生理检测结果.结果 33例CTS中76%为女 性患者,共有病变51侧,单侧病变15例,双侧病变18例.以桡侧3个半手指为主21只手,5个手指均有症状30只手.临床表现为手指麻木、疼痛,可向肘部和肩部放射.电生理检查正中感觉神经传导速度（SCV）异常占96%,正中运动神经潜伏期（DML）延长占66.7%,运动传导速度（MCV）异常54.9%,拇展短肌呈神经源性损害占33.3%.结论 CTS以中年女性多见,临床上以手指麻木、疼痛为主要特点,活动和甩手可使症状减轻.神经电生理检测对CTS的诊断与鉴别诊断中具有重要价值.

Clinical and electroneurophysiological study in patients with carpal tunnel syndrome

[Objective] To explore the clinical features in carpal tunnel syndrome (CTS) and the value of electroneurophysiological examination in the diagnosis. [Methods] The clinical data and the results of electroneurophysiological examination of 33 cases with CTS were retrospectively studied. [Results] In the 33 cases, 76% of the patients were females. Among 51 hands having clinical symptom, there were 15 cases with unilateral hand, 18 cases with bilateral hands. The clinical manifestation of CTS consisted pain and paresthesia in the areas supplied by the median nerves, which became more severe at night, and might be relieved or alleviated by shaking the hands. Among the 51 hands, there were 49 hands (96%) with slow sensory conduction velocity (SCV), 28 hands (54.9%) with slow motor conduction velocity (MCV), 17 hands (33.3%) with neuron deficit in abductor pollicis brevis. [Conclution] Pain and paresthesia in the areas supplied by the median nerves are the promient symptoms in CTS. Electroneurophysiological examination plays an important role in the diagnosis and the definite diagnosis of CTS.
