OBJECTIVE
Stent fracture is a risk factor for stroke. It has not been fully elucidated whether stent-in-stent procedures can effectively treat stent fractures.
CASE PRESENTATION
An 80-year-old man underwent carotid artery stenting (CAS) with an open-cell stent to treat asymptomatic right internal carotid artery (ICA) stenosis. Type III stent fracture occurred during CAS. Six months later, in-stent stenosis progressed on DSA. Repeat CAS with a closed-cell stent was performed. CT showed expansion of the narrowed lumen. The patient remained stroke-free and carotid artery restenosis did not occur for 3 years postoperatively.
CONCLUSION
Repeat CAS with a closed-cell stent is a viable treatment option for stent fracture.
目的
支架断裂是中风的一个危险因素。支架套叠术是否能有效治疗支架断裂尚未完全阐明。
病例介绍
一名80岁男性接受了使用开放式支架的颈动脉支架置入术（CAS），以治疗无症状的右侧颈内动脉（ICA）狭窄。在CAS过程中发生了III型支架断裂。6个月后，数字减影血管造影（DSA）显示支架内狭窄进展。遂使用闭合式支架重复进行CAS。CT显示狭窄管腔扩张。患者术后3年未发生中风且未出现颈动脉再狭窄。
结论
使用闭合式支架重复进行CAS是治疗支架断裂的一种可行选择。
