扭颈后脑血流图诊断椎基底动脉缺血性眩晕的可靠性研究

The reliability study on the test of vertebrobasilar transient ischemic vertigo with encephaloimpedancegram after kinking neck

应用扭颈后脑血流图和高刺激率（５１次／ｓ）听性脑干反应（ＡＢＲ），检查６７例椎基底动 脉缺血性眩晕（ＶＢＴＩＶ）患者。结果显示：扭颈后脑血流图检查结果与高刺激率ＡＢＲ ５１次／ｓ－ １１次／ｓ、Ⅴ波、Ⅰ～Ⅴ间期的异常率是一致的（分别为４６．２７％：６１．１９％；４６．２７％：４４．７８％，Ｐ＞ ０．０５）；两种诊断方法合用的阳性率明显提高（７７．６１％）。提示：扭颈后脑血流图检查对ＶＢＴＩＶ的 诊断是有意义的，其可靠性肯定，在眩晕门诊中可作为一种辅助检查方法与筛选指标。

67 patients with vertebrobasilar transient ischemic vertigo (VBTIV) were examined with encephaloimpedancegram after kinking neck (KNEIG) and the increasing stimulus rate (51/see)auditory brainstem response (ISRABR). The results showed that the positive findings of KNEIG were identical to the abnormal rate of ISRABR for VBTIV (X2 test, P> 0. 05),KNEIG combine with ISRABR could increase the objective information for the diagnosis of VBTIV. The study indicated that KNEIG was a reliable method for the diagnosis of VBTIV. It can be used as a supplementary examination and screening index in the vertigo clinic.
