Methods 34 patients with vertebral basilar artery stenosis diagnosed by DSA were treated with cerebral angioplasty and stenting(CAS ) operation by flexible balloon expandable stents. Results 36 stents were placed in 34 patients. The achievement ratio of operation was 100%. All stenosis showed by DSA were successfully improved without complications.The mean stenosis rate of preoperation and postoperation were (78.3?6.2)% and (3.6?4.2)% respectively. During the further follow up period of 6～38 months, clinical symptoms were disappeared in 31 patients, relieved in 2 patients, recurred in 1 patient.There were no vertebro-basilar system transient ischemic attack and brain infarction onset in those patients.Conclusion Stent angioplasty is safe and effective in the treatment of symptomatic vertebral artery stenosis.
