| 摘 要： | 目的 观察和总结后半规管良性阵发性位置性眩晕(PSC-BPPV)急性发作时的临床特征,为临床诊断提供依据。 方法 回顾性分析115例PSC-BPPV患者急性发作时的临床表现,分析并总结患者的性别和年龄分布、发病时状态、头晕性质、眩晕发作与头部活动间的关系、眼震、伴随症状、辅助检查等临床特征。 结果 PSC-BPPV急性发作时的临床表现具有以下特征:(1)女性多于男性;(2)易累及50岁以上人群;(3)在起床、躺卧、翻身或活动中头部主动或被动到某一位置时突然发病,特别是晨起发病居多;(4)剧烈的眩晕伴有恶心、呕吐;(5)部分患者在初次查体时表现出旋转性眼震;(6)不伴有耳蜗和神经系统症状和体征;(7)颅脑影像学检查无阳性相关发现。 结论 急诊时如患者在起床、躺下、翻身或头部活动到某一位置时突然出现剧烈的眩晕发作,不伴有耳蜗和神经系统症状体征,颅脑影像学检查无相关阳性发现,应当考虑PSC-BPPV的诊断,及早行Dix-Hallpke诱发试验能够确立诊断。

| Abstract: | Objective To observe and summarize the clinical characteristics of posterior semicircular canal benign parox-ysmal positional vertigo(PSC-BPPV)at the time of acute onset,and to provide the clinical evidences for earlier diagno-sis.Methods The clinical manifestations at the time of acute onset of 1 15 cases of patients with PSC-BPPV diagnosed were collected retrospectively.The gender,distributions of age,character of dizziness,state of patients at the time of a-cute onset,relationships between vertigo attack and head movement,nystagmus,associated symptoms,and auxiliary examination were analyzed.Results The clincal characteristics of PSC-BPPV at the time of acute onset were summa-rized as follow:① incidence among female patients was more higher than that of male patients;②participants aged o-ver 50 years-old were more vulnerable to be affected;③ acute vertigo occurred mainly at time of getting up,lying down,turning over or moving head actively or passively to a certain position,especially getting up in the morning;④the onset of severe vertigo was associated with nausea and vomitting;⑤ part of patients presented characteric rotatory nystagmus of PSC-BPPV at the time of initial routine physical examination;⑥without symptoms and signs of cochlear and nervous system;⑦ without related positive findings by cranial imaging(CT or MRI).Conclusion The diagnosis of PSC-BPPV should be considered if patients presented vertigo attack suddenly but without symptoms and signs of co-clear and nervous system and related positive findings by cranial imagings.It is helpful to earlier confirming of the diag-nosis by performing Dix-Hallpike manuvre. |
