title: [Clinical observation on Qingling Dingxuan Decoction in treating vertigo cause by insufficient blood-supply of ventebrobasilar artery].
abstract: OBJECTIVE
  To observe the therapeutic effect of Qingling Dingxuan Decoction (QDD) on vertigo caused by insufficient blood-supply of ventebrobasilar artery (IBVA).
  
  
  METHODS
  Thirty-nine patients were divided into the flunarizine group (n=19) and the QDD group (n=20) treated with respective medicine on the base of routine treatment with Chinese and Western medicine. The clinical efficacy and recurrent rate were observed and compared.
  
  
  RESULTS
  Compared with those in the flunarizine group, clinical curative effect was better, recurrent rate lower, symptom score higher, hemorheological parameters and transcranial doppler indexes were improved more significant in the QDD group (P < 0.01 or P < 0.05).
  
  
  CONCLUSIONS
  QDD had obvious therapeutic effect on IBVA. Improvement of microcirculation and reduction of blood viscosity may be one of the therapeutical mechanisms.
