过滤伞保护下的颈动脉狭窄支架成形术

Use of filter device during angioplasty and stent placement for the treatment of carotid stenosis

目的 分析过滤伞保护下颈动脉狭窄支架成形术的安全及有效性。方法 2 5例症状性颈动脉狭窄支架成形术中采用过滤伞装置 ,首先将过滤伞通过狭窄部位并释放 ,然后进行狭窄的血管内支架成形术 ,观察手术期脑栓塞发生的情况 ,大体观察回收的过滤伞。结果 2 5例过滤伞放置及支架成形术均成功实施 ,回收的过滤伞中 15个发现组织碎片 ,无手术死亡及症状性脑血栓栓塞并发症 ,临床短期随访无脑缺血事件发生。

Objective To analyze the ef fect of filter device in the prevention of cerebral embolic events during carotid angioplasty and stent placement Methods Angioguard was used in the treatment of 25 patients of symptomatic carotid artery stenoses by angioplasty and stenting The filter devices were placed distally to the stenoses and deployed before angioplasty and stent placement Cerebral thromboembolic events were noted and the filter devices were macroscopically observed Results The filter devices were placed and carotid angioplasty and stenting were successfully administered in all 25 patients Debris could be found macroscopically in 15 out of 25 retrieved filters There was no death or symptomatic cerebral thromboembolic events during the procedure Short-term clinical follow-up showed excellent results Conclusion Use of filter device may improve the safety of carotid angioplasty and stent placement
