title: [Part of the vertebral artery in patients with sudden deafness].
abstract: OBJECTIVE
  To explore the characteristics of vertebral artery system in the patients with sudden deafness by using digital subtraction angiography (DSA).
  
  
  METHODS
  Thirty-four cases of sudden deafness with vertebrobasilar artery ischemia confirmed by the color doppler ultrasound were undergone DSA in both side. The characteristics of vertebral artery, basal artery and before-cerebellum artery were analysis before specific therapy.
  
  
  RESULTS
  There is no related complication were occurred among 34 cases. Side vertebral artery was blocked in 2 cases, atherosclerosis was found in 5 cases. The right cerebellar artery anterior and the left cerebellar artery posterior were found filling defect or minor change in 29.4% (10/34) and 35.3% (12/34) of the patients, respectively. The right and the left arteria auditiva interna were found filling defect or minor change in 64.7% (22/34) and 73.5% (25/34) of the patients, respectively. After specific therapy, 8 cases were cured, the hearing of 9 cases were markedly improved, the hearing of 12 cases were improved efficient and 5 patients have no hearing improvement, the total effective rate was 85.3%.
  
  
  CONCLUSIONS
  The arteria auditiva interna and inferior anterior arteria cerebelli caused inner ear ischemia were found in the patients with sudden deafness. The using of vasodilator may have satisfactory and positive curative effect in the therapy of sudden deafness.
