摘要
为了解椎基底动脉短暂缺血性眩晕（ｖｅｒｔｅｂｒｏｂａｓｉｌａｒｔｒａｎｓｉｅｎｔｉｓｃｈｅｍｉｃｖｅｒｔｉｇｏ，ＶＢＴＩＶ）患者ＡＢＲ与经颅多普勒（ＴＣＤ）的相关性，对２４例（４８耳）临床诊断ＶＢＴＩＶ患者及１２例（２４耳）其他眩晕患者进行了检测。结果发现：ＶＢＴＩＶ组ＡＢＲ异常率为５８．３％，ＴＣＤ异常率为５４．２％，χ２检验差异无显著性意义；其他眩晕组ＡＢＲ异常率为８．３％，ＴＣＤ异常率为４５．８％，χ２检验差异有显著性意义。ＶＢＴＩＶ组ＡＢＲ及ＴＣＤ皆为异常者为１９／４８，皆为正常者为１３／４８，两者占６６．７％；其他眩晕组两者皆异常者为０，皆正常者为１１／２４，占４５．８％。根据临床征象，结合高刺激率ＡＢＲ及ＴＣＤ的测试结果可能提高对ＶＢＴＩＶ的诊断价值，而单独的ＴＣＤ结果不足以作为诊断依据。
