视频眼震电图在以眩晕为主诉的后循环缺血患者诊断中应用价值

The Value of Video Nystagmus in the Diagnosis of Patients with Posterior Circulation Ischemia withDizziness as the Main Complaint

目的:分析在以眩晕为主诉的后循环缺血患者中应用视频眼震电图(VNG)的诊断价值。方法:将2017年10月~2018年10月在本院就诊的64例以眩晕为主诉的后循环缺血患者纳入研究,将其设为实验组;同时选取36例体检健康者作为对照组。两组对象均接受VNG检查,对比视动系统检查、自发性眼震、位置性眼震结果。结果:视动系统检查中实验组53例(82.81%)患者存在一项或多项异常,明显高于对照组,差异具有统计学意义(P<0.05);实验组17例(25.00%)自发性眼震,29例(45.31%)位置性眼震,明显多于对照组,差异具有统计学意义(P<0.05)。结论:VNG应用于以眩晕为主诉的后循环缺血患者中,临床表现相较于正常人群存在较大差异,可有效反映病变情况,诊断价值明显。

Objective:To analyze the diagnostic value of video nystagmus(VNG)in patients with posterior circulation ischemia whose main complaint is dizziness.Methods:Sixty-four patients with post-circulation ischemia whose main complaint was dizziness in our hospital from October 2017 to October 2018 were included in the study,and they were set as the experimental group.At the same time,36 healthy people with physical examination were selected as the control group.Both groups of subjects underwent VNG examination,and the results of optokinetic system examination,spontaneous nystagmus,and positional nystagmus were compared.Results:53 patients(82.81%)in the experimental group had one or more abnormalities in the visual inspection system,which were significantly higher than those in the control group.The difference was statistically significant(P<0.05);17 patients(25.00%)in the experimental group were spontaneous.Nystagmus,29 cases(45.31%)of local nystagmus were significantly more than the control group,the difference was statistically significant(P<0.05).Conclusion:VNG is used in patients with posterior circulation ischemia whose main complaint is dizziness.Compared with the normal population,there is a large difference,which can effectively reflect the condition of the disease and has obvious diagnostic value.
