摘要
目的探讨症状性椎／锁骨下动脉狭窄支架术后支架断裂的发生机制和防治措施。方法回顾性分析3例症状性椎／锁骨下动脉狭窄支架术后支架断裂患者的临床资料，参考冠状动脉支架断裂分型、发生率与发生时间、发生机制和防治进行相关文献复习。结果3例症状性椎／锁骨下动脉狭窄支架术后支架断裂均与支架内再狭窄和闭塞有关，2例患者采用球囊扩张术后症状减轻，1例患者服药观察，病情无加重。结论椎／锁骨下动脉狭窄支架术后可发生支架断裂，应定期复查：支架断裂可引起症状加重，目前治疗应个体化。
Objective To discuss mechanism and control measures of stent fracture and restenosis after percutaneous transluminal angioplasty and stenting （PTAS） for symptomatic ostial vertebral/subclavian artery stenosis. Methods A retrospective analysis was performed on 3 patients with stent fracture after receiving PTAS for symptomatic ostial vertebral/subclavian artery stenosis. Simple radiographic, ultrasonographic and clinical follow-up examinations were estimated. Related articles on coronary stent fracture were gone over, consulting in the types, cumulative incidence and occurrence time of adverse events, risk factors and preventive measures. Results Stent fractures of 3 patients with symptomatic ostial vertebral /subclavian artery stenosis were associated with in-stent restenosis and occlusion. Two of the 3 patients treated with the balloon angioplasty and after balloon dilatation, and the patients exhibited relief of symptoms. One patient was only managed for vascular disease risk factors, and no developing recurrent symptoms were noted during the follow-up period. Conclusions Stent fracture might appear in patients performed PTAS for symptomatic ostial vertebral subclavian artery stenosis, and regular check is needed. Individual treatment was emphasized in case of serious symptoms appeared.
