Abstract

To investigate the correlation of brainstem response (ABR) and transcranial doppler examination (TCD) on the vertebrobasilar transient ischemic vertigo (VBTIV), 24 patients (48 ears) with VBTIV and 12 patients (24 ears) with non-VBTIV were studied. The results showed that the incidence of abnormality of ABR in VBTIV group was 58.3%, TCD 54.2%, there being no significant difference by Chi-square test; while in non-VBTIV group ABR 8.3%, TCD 45.8%. Both ABR and TCD were abnormal in VBTIV 19/48, non-VBTIV 0/24 and normal VBTIV 13/48, non-VBTIV 11/24. The ratio of there cases (normal and abnormal) as a whole was VBTIV 66.7%, non-VBTIV 45.8%. It indicates that ABR with high stimulus rates combined with TCD and clinical signs can make the diagnosis of VBTIV. The results of TCD alone can't be a considerable diagnostic basis for VBTIV.

摘要

为探讨脑干听觉诱发电位（ABR）及经颅多普勒检查（TCD）与椎基底动脉短暂性缺血性眩晕（VBTIV）的相关性，对24例（48耳）VBTIV患者及12例（24耳）非VBTIV患者进行了研究。结果显示，VBTIV组ABR异常发生率为58.3%，TCD异常发生率为54.2%，经卡方检验二者差异无统计学意义；而非VBTIV组ABR异常发生率为8.3%，TCD异常发生率为45.8%。VBTIV组ABR和TCD均异常者19/48，非VBTIV组为0/24；VBTIV组ABR和TCD均正常者13/48，非VBTIV组为11/24。两组（正常与异常）总体比例为VBTIV 66.7%，非VBTIV 45.8%。提示高刺激率ABR联合TCD及临床症状可对VBTIV做出诊断，单纯TCD结果不能作为VBTIV可靠的诊断依据。
