Description

<p>Objective: We report two cases of atherosclerotic vertebral artery ostium stenosis treated with open-cell type self-expanding stents (SES).</p><p>Case Presentation: Two cases of symptomatic vertebral ostium severe stenosis were treated. Both case showed serious vessel tortuosity, and the plaque extended proximally into the subclavian artery. We concerned about the vessel kinking at the distal stent edge and thromboembolic event from the plaque left behind in the subclavian artery, when we use balloon expandable stents. Therefore, we treated these cases using SESs placed from the vertebral ostium to the proximal subclavian artery. There were no perioperative complications or cerebral ischemic events during follow-up.</p><p>Conclusion: Vertebral artery ostium stenting using SES may be a useful choice from the viewpoint of stent followability to the tortuous vessel, conformability to the arterial wall, and covering property for the plaque extending to the subclavian artery.</p>
