Abstract： Objective： To observe the curative effect of acupuncture combined with Chuanxiong Qingnao granules on cervical spondylosis of vertebral artery type(CSA) and its effect on blood flow of vertebral artery. Methods： A total of 80 cases of CSA patients were enrolled and divided into the treatment group and the control group according to different treatment methods，40 cases in each group. The treatment group was treated with acupuncture combined with Chuanxiong Qingnao granules，and the control group was treated with flunarizine hydrochloride capsules combined with alprostadil injection. Both groups were treated for three weeks. The clinical effect as well as the scores of Evaluation Scale for Cervical Vertigo(ESCV) and Clinical Assessment Scale for Cervical Spondylosis(CASCS) were compared between the two groups. The diameter ，the peak systolic velocity(Vs)，resistance index(RI) and pulsatility index(PI) of vertebral artery in the two groups were detected by color doppler ultrasound. Results：The total effective rate was 95.0% in the treatment group，higher than that of 72.5% in the control group，the difference being significant(P＜0.05). After treatment，the scores of vertigo(degree，frequency and duration)， neck and shoulder pain， headache， daily living and work， mentality and social adaptation in ESCV in the two groups were increased when compared with those before treatment，and each score in the treatment group was higher than that in the control group， differences being significant(P＜0.01). After treatment， the scores of CASCS in the two groups were increased when compared with those before treatment(P＜0.01)； the score of CASCS in the treatment groups was higher than that in the control group(P＜0.01). After treatment，there was no significant difference in the comparison of the score of cervical degeneration between the two groups(P＞0.05). After treatment，the values of diameter and Vs of vertebral artery in the two groups were increased(P＜0.05)，and the values of RI and PI of vertebral artery were decreased(P＜0.05)； the values of diameter and Vs in the treatment group were larger than those in the control group(P＜0.05)，and the values of RI and PI were lower(P＜0.05). Conclusion： The therapy of acupuncture combined with Chuanxiong Qingnao granules can effectively relieve vertigo and complications in CSA patients，and improve cervical function and the blood supply of vertebral artery.
