Objective To investigate the effects of heat-sensitive moxibustion combined with uncture and bloodletting on hemorheology and cerebral blood flow parameters of cedar spondylosis of ertebral artery type (CSA). Methods A total of 130 patients with CSA who met the inclusion criteria were andomly divided into 2 groups, 65 patients in each group. The observation group was treated with heat-sensitive oxibustion combined with blood-letting, and the control group was treated with conventional acupuncture. oth groups were treated for 14 days. The Transcranial Doppler was used to monitor the peak velocity of ystolic (Vs) of the intracranial vertebral artery and basilar artery, the peak velocity of diastolic (Vd) and the esistante index (RI). The whole blood viscosity (RBV), plasma specific viscosity (RPV), the hematocrit HCT) and the erythrocyte sedimentation rate (ESR) were detected and the clinical efficacy was evaluated.Results The total effective rate was 93.9% (61/65) in the observation group and 80.0% (52/65) in the control roup. The difference between the two groups was statistically significant (χ2=5.482, P=0.019). After treatment,the RBV, the RPV, HCT and ESR in the observation group were significantly lower than the control group. The Vs on the left side of the vertebral artery in the observation group was significantly higher than that in the control group (t=2.087, P=0.039), and the Vs and Vd in the right vertebral artery were significantly higher than the control group (t values were 3.505, 3.161, respectively, all Ps<0.01). The RI of the observation group was significantly lower than the control group (t=2.425, P=0.017). The Vs and Vd of the basilar artery in the observation group were significantly higher than the control group (t values were 2.716, 4.748, all Ps<0.01), and the RI was significantly lower than the control group (t=3.299, P=0.001). Conclusions Moxibustion combined with bloodletting can relieve the symptoms of CSA patients, improve the vertebrobasilar blood supply and improve clinical efficacy.
