良性阵发性位置性眩晕48例误诊临床分析

目的：探讨48例良性阵发性位置性眩晕患者的临床误诊原因及确诊后治疗方法及疗效。方法对48例误诊患者诊治过程进行回顾性分析。结果48例患者入院时误诊为后循环缺血性眩晕28例、梅尼埃病8例、高血压病5例、颈性眩晕5例、脑梗死2例；后确诊为后半规管BPPV 39例，外半规管BPPV 9例；所有误诊病例确诊后予手法复位均痊愈。结论凡是与头位变动相关且持续时间短的眩晕发作，应行Dix-hallpike试验及平卧侧头诱发试验以避免误诊；明确诊断后予行手法复位，疗效明确。

Clinical analysis of 48 cases of misdiagnosised patients with benign paroxysmal positional vertigo

Objective To investigate clinical misdiagnosis reasons, curative method and effect of 48 patients with benign paroxysmal positional vertigo.Methods The process of diagnosis and treatment were retrospectively analyzed for the 48 patients.Results All 28 patients were misdiagnosed for posterior circulation ischemia vertigo, 8 cases for Meynier＆#39;s disease, 5 cases for hypertension, 5 cases for cervical vertigo, 2 cases for cerebral infarction; later 39 cases were diagnosed for posterior semicircular canal BPPV, 9 cases were diagnosed for lateral semicircular canal BPPV; all misdiagnosed cases were recovered by giving manipulative reduction after definite diagnosis.ConclusionUsually when patients have vertigo associated with head movements and short duration, Dix-hallpike test and supine side head evoked tests should be performed in order to avoid misdiagnosis. Curative effect of giving manipulative reduction after definite diagnosis is clear.
