中老年患者以眩晕为首发症状就诊者并非少见,此种患者多有动脉粥样硬化和颈椎病。临床检查大多未发现阳性体征,客观检查方法不多,头颅CT不易发现病变。脑干听觉诱发电位(BAEP)试验能敏感的反应听觉系统的神经电生理功能。本文对60例椎-基底动脉缺血45岁以上病人进行脑干听觉诱发电位检查异常率达85％,此项检查可成为诊断椎-基底动脉缺血的重要客观指标之一,现已用于临床。1 临床资料本组患者中女28例,男32例,年龄为45～72岁,平均55.9岁。发病主要症状为眩晕、头晕、耳鸣、耳聋、恶心、呕吐、行走不稳、视力障碍、半身或四胶面部麻木、嗜睡等。其中高血压7例、双眼底动
Middle-aged and elderly patients with vertigo as the first symptom treatment is not uncommon, such patients often have atherosclerosis and cervical spondylosis. Most of the clinical examination found no positive signs, objective methods of examination are few, cranial CT is not easy to find lesions. Brainstem Auditory Evoked Potentials (BAEP) test responds sensitively to the electrophysiological function of the auditory system. This article 60 cases of vertebrobasilar ischemia in patients over the age of 45 brainstem auditory evoked potential test abnormalities rate of 85%, this examination can be diagnosed vertebrobasilar ischemia one of the important objective indicators, has been used in clinical. 1 clinical data of 28 patients in this group of patients, 32 males, aged 45 to 72 years, mean 55.9 years old. The main symptoms of dizziness, dizziness, tinnitus, deafness, nausea, vomiting, walking instability, visual impairment, half body or four plastic facial numbness, lethargy and so on. Among them, 7 cases of hypertension, both eyes move
