Endovascular treatment of vertebral artery (VA) origin stenosis typically requires placement of the proximal end of the stent within the lumen of the subclavian artery or aorta to provide complete coverage of the ostial lesion. This configuration may complicate subsequent endovascular access into the stented VA. We describe a technique modification of VA origin stenting and angioplasty with a monorail angioplasty balloon system designed specifically for dilation of the ostial origin which may be helpful in conforming the proximal portion of the stent to the VA origin. Simplified endovascular access to the VA origin after angioplasty is demonstrated.
椎动脉（VA）起始段狭窄的血管内治疗通常需要将支架的近端置于锁骨下动脉或主动脉的管腔中，以提供对开口病变的完全覆盖。这种构型可能会使随后对支架 VA 的血管内进入变得复杂。我们描述了一种VA 开口支架置入和血管成形术的技术改良，使用了一种专为扩张开口起源而设计的单轨血管成形球囊系统，这可能有助于使支架的近端与 VA 开口相适应。血管成形术后 VA 开口的简化血管内进入得到了展示。
