摘　　要：目的探索眩晕综合症与后循环血管变异的相关性。方法对本院123例患有眩晕综合症的患者在急性期进行头颈部血管彩超检查,并对颈部血管血流动力学变化情况进行检测,应用头颈部CTA检查显示动脉形态学变化。结果颈部血管彩超显示:对照组椎动脉平均血流速度明显高于观察组(P<0.05);头颈部CTA显示:与对照组相比,观察组孤立性椎动脉、椎动脉发育不良及胚胎型大脑后动脉的后循环血管变异的发生率明显升高,差异具有统计学意义(P<0.05);以椎动脉发育不良最明显。结论眩晕与后循环血管变异发生具有明显相关性。Objective To investigate the correlation between abnormal development of vertebral artery and vertigo syndrome. Methods A total of 123 patients with vertigo syndrome were performed with color Doppler ultrasound and CT angiography（CTA）, and the hemodynamic changes were detected. The morphological changes of the arteries were revealed by the CTA examination. Results Cervical vascular color Doppler ultrasound showed that the average blood flow velocity of vertebral artery in the control group was significantly higher than that in the observation group（P〈0.05）. And the results of CTA shows the proportion of isolated vertebral artery, hypoplastic vertebral artery and fetal posterior cerebral artery in observation group were significantly higher compared with control group. Conclusion Abnormal development of vertebral artery is correlated with vertigo syndrome.
