Assessment of the Efficacy on Posterior Circulation Ischemic Vertigo(PCIV) Treated with Buqi Huoxue Dingyun Formula

Objective To observe the efficacy of buqi huoxue dingyun formula on posterior circulation ischemic vertigo(PCIV)of qi deficiency and blood stagnation type.Methods 100 cases were randomized into a treatment group and a control group,50 cases in each one.In control group,divitamins,notoginseng and cinarizine capsules and intravenous drop with shuxuening injection were administered.In treatment group,on the basis of the treatment as control group,buqie huoxue dingyun formula was added.14-day treatment made 1 session.Before and after treatment,the Transcranial Doppler(TCD)was adopted to detect the mean velocity(Vm)and the systolic velocity(Vs)in bilateral vertebral arteries and basilar artery separately.Meanwhile,Basel Index was scored.At the end of 1 session treatment,the clinical efficacy was assessed.Results After treatment,the improvements of vertebral-basilar artery blood flow velocity parameters,and Basel-Index score in treatment group presented statistical difference as compared with control group(P0.05).The total effective rate was 96.0% in treatment group and was 82.0% in control group.The total effective rate in treatment group was better than that in control group,indicating statistical significance(P0.05).Conclusion Buqi huoxue dingyun formula is effective in the treatment of PCIV of qi deficiency and blood stagnation type and has no apparent adverse reaction reported.
