This report describes a solution for a restenosis and for the fracture of a stent in the vertebral artery in a patient suffering from vertebrobasilar symptoms. Angiography demonstrates restenosis of a vertebral stent as well as its fracture and migration into the subclavian artery. This complication was managed percutaneously by passing a guide wire through the fractured stent. Pre-dilatation and kissing balloon techniques were applied in both the vertebral and subclavian arteries to modify the stent's dimensions and shape it into the form of a "ring." Postprocedural angiography demonstrated an excellent final result with the assistance of StentBoost visualization. Control angiography at six months also utilized StentBoost imaging and confirmed the patency of the bifurcation and that the stent was not displaced.
本报告描述了一种针对患有椎基底动脉症状患者椎动脉内支架再狭窄及支架断裂的解决方案。血管造影显示椎动脉支架出现再狭窄、断裂并移位至锁骨下动脉。通过将导丝穿过断裂的支架，经皮处理了这一并发症。在椎动脉和锁骨下动脉均应用了预扩张和双球囊技术，以改变支架尺寸并将其塑形为“环形”。术后血管造影在StentBoost可视化技术的辅助下显示出极佳的最终效果。六个月时的对照血管造影同样采用了StentBoost成像，证实了分叉处通畅且支架未移位。
