摘要 目的分析眩晕患者椎-基底动脉(V-BA)的经颅多普勒(TCD)表现,探讨眩晕发病机制及TCD的应用价值。方法对217例眩晕患者(观察组)及157例无眩晕的正常者(对照组)的V-BA的TCD资料进行回顾性分析。结果 (1)观察组V-BA流速异常(包括狭窄)166例(76%),对照组V-BA流速异常19例(12%),差别有统计学意义(<0.01)。(2)观察组中男性V-BA流速减慢58例,流速增快19例,女性V-BA流速减慢31例,流速增快54例,流速差别在性别上有统计学意义(<0.01)。(3)观察组与对照组中分别有67例、11例提示血管顺应性降低或脑动脉硬化,两组差异有统计学意义(<0.01)。结论 TCD检查能直接反映V-BA血流动力学及血管本身变化方面的参数,为临床提供病情监测,并为进一步明确诊断、治疗及预防提供指导意义。
