摘  要:后循环缺血是一种临床常见的缺血性脑血管病,包括后循环短暂性脑缺血发作和脑梗死。后循环梗死患者的临床表现复杂多样,诊断主要是依据临床表现和影像学,而后循环短暂性脑缺血发作,发作间期既没有明显的阳性体征,又缺乏影像学的典型表现,诊断困难。脑干听觉诱发电位反映的是听神经及脑干听觉传导通路的电生理机能,使用脑干听觉诱发电位特别是高刺激率脑干听觉诱发电位检查来诊断后循环缺血,扩大和丰富了诊断手段,对其早期诊断有着重要意义,但仍存在着较多值得思索的问题。Posterior circulation ischemia is an ischemic cerebrovascular disease frequently seen in clinical practice,which includes transient ischemic attack and cerebral infarction of the posterior circulation.The clinical manifestations of patients with posterior circulation infarction are complex and varied,and diagnosis is mainly based on clinical manifestations and imaging.Transient ischemic attacks in the posterior circulation have neither obvious positive signs nor typical imaging manifestations during the interictal period,making the diagnosis difficult.Brainstem auditory evoked potentials reflect the electrophysiological functioning of the auditory nerves and brainstem auditory conduction pathway.The use of brainstem auditory evoked potentials,especially brainstem auditory evoked potentials at high stimulation rates,in diagnosing posterior circulation ischemia expands and enriches diagnostic methods,which is of great significance for the early diagnosis of the disease.However,there are still many problems worth considering.
