title: Follow-up of extracranial vertebral artery stents with Doppler sonography.
abstract: OBJECTIVE
  The objective of our study was to determine the Doppler sonography findings suggestive of restenosis in the follow-up of patients treated by stent placement in the extracranial vertebral artery.
  
  
  CONCLUSIONS
  Follow-up of vertebral artery stents with Doppler sonography may be performed by direct insonation of the stent or by indirect measurements from the V2 segment (the part of the vertebral artery that courses within the intervertebral foramina). The V2 segment Doppler sonography measurements may guide future examinations and provide essential information regarding the proximally deployed stent.
