目的：：探讨脑干听觉诱发电位( BAEP)对椎基底动脉系统短暂性脑缺血发作( VBTIA)患者的诊断及转归的临床意义。方法：对确诊的VBTIA患者行BAEP监测，以Ⅰ~Ⅴ波各波波峰潜伏期( PL)和/或Ⅰ~Ⅲ、Ⅲ~Ⅴ、Ⅰ~Ⅴ各峰间潜伏期及其比值为观察指标。结果：2组患者BAEP检测各波PL、IPL和Ⅰ~Ⅲ/Ⅲ~Ⅴ异常率差异均无统计学意义(P>0.05)；VBTIA组患者BAEP各波PL和IPL值均明显低于后循环脑梗死组(P<0.01)。结论：BAEP可作为VBT早期诊断的辅助检查，以Ⅰ~V波各波 PL和/或Ⅰ~Ⅲ、Ⅲ~Ⅴ、Ⅰ~Ⅴ各IPL及其比值为主要检测指标，且其异常显著者易转归为脑梗死。

Objective:To explore the clinical significance of brainstem auditory evoked potential ( BAEP ) in the diagnosis and prognosis of transient ischemic attack of vertebral basilar artery system(VBTIA). Methods:The BAEPs of patients with VBTIA were monitored. The peak latency( PL) value ofⅠtoⅤwave and( or) interpeak latency( IPL) values ofⅠtoⅢwave,ⅢtoⅤwave andⅠ toⅤwave,and the ratio of PL to IPL were observed. Results:The differences of the PL,IPL and abnormal rate ofⅠtoⅢ/ⅢtoⅤbetween two groups were not statistically significant(P>0. 05). The values of PL and IPL of BAEP in VBT group were significantly lower than those in posterior circulation cerebral infarction(P<0. 01). Conclusions:BAEP can be used as the auxiliary examination in early diagnosis of VBTIA. The PL value ofⅠtoⅤwave and( or) the IPL values ofⅠtoⅢwave,ⅢtoⅤwave andⅠtoⅤwave, and the ratio of PL to IPL are the main indicators, and the patients with abnormal indicators can easily transform into cerebral infarction.
