经颅多普勒和脑干听觉诱发电位对椎-基底动脉供血不足的诊断价值

The Diagnostic Value of Transcranial Doppler and Brain Auditory Evoked Potentials in Patients with Vertebrobasilar Insufficiency

目的探讨经颅多普勒(TCD)和脑干听觉诱发电位(BAEP)对椎-基底动脉供血不足(VBI)的诊断价值。方法对86例临床诊断为VBI的病人和正常人分别进行TCD、BAEP检查,并对检查结果进行分析。结果VBI组TCD和BAEP结果与对照组比较有统计学意义,TCD检查异常率为75.6%,BAEP检查异常率67.4%,经χ2检验无统计学意义;结论结合TCD和BAEP检查有助于VBI的诊断,单独的TCD检查不足以作为VBI的诊断依据。

Objective To explore the diagnostic value of transcranial Doppler （TCD） and brain stem auditory evoked Potential （BAEP） in patients （pts） with vertebrobasilar insufficiency （VBI）. Methods TCD and BAEP were performed in 86 pts with VBI, and the results were analyzed and compared with 50 normal subjects. Resuits For TCD and BAEP, there were significant difference between the pts with VBI and normal subjects. The abnormality rate was 75.6 % for BAEP, and 67.4 % for BAEP in pts with VBI. there is no significant difference between TCD and BAEP. Conclusion Combination of TCD and BAEP might increase the value for diagnosis of VBI. The results suggest that TCD alone may not be a useful way for VBI.
