title: [Pathomorphological change of the atlanto-occipital segment of vertebral artery related with cervical vertigo].
abstract: OBJECTIVE
  To explore the pathomorphological change of the atlanto-occipital segment of vertebral artery (V3 part) related with cervical vertigo.
  
  
  METHODS
  From June 1999 to November 2011, the pathomorphological change of the atlanto-occipital segment of vertebral artery were observed in 1680 patients with cervical vertigo using 3D-CTA technology. The clinical data of these patients were analyzed. There were 783 males and 897 females, aged from 22 to 70 years old with an average of 52.8 years old. Doppler examination showed vertebral basilar artery flow velocity to speed up or slow down.
  
  
  RESULTS
  The blood vessel of 3360 branches were detected in 1680 patients and 2778 branches were detected out vascular anomaly. And 829 branches were in V1 segment, 421 were in V2, 328 were in V3, 1190 were in V4. The pathomorphological changes in the atlanto-occipital segment (V3) of vertebral artery included angiospasm, congenital absence, abnormal exit, localized stenosis.
  
  
  CONCLUSIONS
  There are 4 kinds of pathomorphological changes in the atlanto-occipital segment of vertebral artery related with cervical vertigo. The 3D-CTA result can be used to judge prognosis and adopt reasonable treatment for the patients.
