脑保护装置下的颈动脉狭窄支架成形术

目的评价脑保护装置下的颈动脉狭窄支架成形术的有效性和安全性。方法22例患者在颈动脉狭窄支架成形术中联合使用了脑保护装置，首先将脑保护装置（过滤伞）小心通过狭窄部位放置于颈动脉狭窄的远端并释放，然后再行颈动脉狭窄支架成形术，观察手术期缺血性脑血管病事件及其他并发症。结果22例脑保护装置及支架均成功实施，支架释放前颈动脉的平均狭窄率为（84±9）％，支架成形术后的平均狭窄率降为（21±8）％（P〈0．01），手术期无缺血性脑血管病事件发生。结论脑保护装置能有效提高颈动脉狭窄支架成形术的安全性。

The effect of carotid artery stenting under cerebral protection device

Objective To investigate the efficacy and safety of carotid artery stenting (CAS) under cerebral protection device for patients with carotid stenosis. Methods 22 patients with carotid artery stenosis had been carried out carotid artery stenting under cerebral protection device, cerebral protection device (filters umbrella)was placed carefully distally to the stenoses and deployed before carotid artery stenting. During the operation the incident of ischemic cerebrovascular disease and other complications were observed.Results Cerebral protection device and endovascular stenting were successfully implemented in all patients , the mean diameter of stenosis procedure was (84 ± 9)% and reduced was (21 ± 8)% after carotid artery stenting (P <0.01), There were no cerebral ischemia event and other complications during the procedure. there was no endovascular narrow during six months follow-up.Conclusion cerebral protection devices can improve the safety of carotid artery stenting
