【摘要】 目的 分析椎基底动脉供血不足(VBI)患者血管狭窄和缺血发作的关系。方法 选择2002年4月～2005年12月神经内科临床拟诊为VBI的中老年住院患者125例，全部进行数字减影主动脉弓及全脑血管造影检查，分析脑动脉狭窄的发生情况。结果 69例患者存在颈及颅内动脉粥样硬化狭窄或闭塞；其中单纯前循环病变8例，后循环病变61例；累及两条或两条以上血管的共53例；以椎动脉合并其他血管狭窄最为常见。狭窄的分布依次为椎动脉35例，颈内动脉26例，锁骨下动脉8例，基底动脉6例，大脑后动脉4例，大脑中动脉1例。69例脑动脉狭窄患者中仅有37例与临床表现相符。结论 颈及颅内血管粥样硬化性狭窄是导致中老年VBI的主要原因。血管粥样硬化性狭窄导致VBI的可能机制为：(1)前或后循环责任血管狭窄；(2)盗血综合征；(3)多发血管狭窄；(4)动脉-动脉栓塞。
