血栓保护伞在颈动脉狭窄支架成形术中的应用

目的：分析血栓保护伞应用于颈动脉狭窄支架成形术的效果。方法：19例症状性颈动脉狭窄支架成形术时采用血栓保护伞，首先将血栓保护伞通过狭窄部位并释放，然后进行支架成形术，观察手术期脑栓塞发生情况，大体观察回收支架。结果：19例血栓保护伞放置及支架成形均成功实施，回收的保护伞中13个发现碎片组织，无手术死亡及血栓栓塞并发症，临床短期随访无脑缺血事件发生。结论：使用血栓保护伞可能提高颈动脉狭窄支架成形术的安全性。

Angioguard preventing cerebral embolic events during carotid angioplasty and stent placement

Objective: To analyze the effect of filter device in the prevention of cerebral embolic events during carotid angioplasty and stent placement.Methods: Angioguard was used in the treatment of 19 patients with symptomatic carotid artery stenosis by angioplasty and stenting.The filter devices were placed distal to the stenosis 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 the 19 patients.There were no operational death and cerebral thromboembolic events during the procedure.Short term clinical follow up showed excellent outcome with no cerebral ischemia.Conclusion: Angioguard may improve safety of carotid angioplasty and stent placement.
