头晕、眩晕患者行经颅多普勒超声检测的临床意义

Clinical value of TCD measuring in patients with dizziness or vertigo

对 2 15 9例头晕、眩晕患者进行经颅多普勒 (TCD)检测 ,其中合并高血压 2 6 9例 ,糖尿病 5 8例。结果显示 :114.2 7%的患者血管狭窄 ,8.6 6 %血流速度减慢 ;眩晕者椎动脉狭窄率明显高于头晕者 ,二者有显著性差异。2老年患者颈内动脉系统狭窄和椎基底动脉系统血流速度降低较明显。3高血压、糖尿病与颅内血管狭窄有明显相关性。提示临床上不能把单纯眩晕、头晕患者诊断为功能性疾病或椎基底动脉供血不足。

patients with dizziness or vertigo(HT 269 cases,DM 58 cases) were measured by TCD The results showed that there were 14 27% patients with vessel stenosis and 8 66% patients with decreased flow velocity The incidence of vertebrobasilar artery stenosis in vertigo group was high and there was significant difference between the two groups Stenosis of carotid system and slow flow velocity of posterior circulation were more common in aged subjects HT and DM were correlated significantly with intracranianl vascular stenosis The results suggest that patients with simple vertigo or dizziness can not be diagnosed as with functional disease or vertibro basilar artery defficiency
