颈动脉狭窄在脑保护装置下的支架置入治疗

目的探讨颈动脉狭窄患者支架治疗中的脑保护装置的有效性和安全性及治疗意义。方法对14例颈动脉狭窄患者进行血管内支架治疗。全部应用了脑保护装置(滤网型)。结果14例患者成功地释放了18枚自膨式支架。其中2例发生微栓子脱落轻度卒中,治疗1～3d完全恢复,颈动脉狭窄6例出现短暂性心率减慢和低血压。随访期所有患者均未发生脑梗死。结论在支架治疗中,脑保护装置的应用可减少治疗中的神经并发症,是一种有效和安全的治疗方法。

Carotid Artery Stenosis:The Treatment by Carotid Stenting with Cerebral Protection Devices

Objective To explore the safety,efficacy and clinical significance of stenting with cerebral protection devices for carotid artery stenosis.Methods 14 patients with carotid artery stenosis were treated by intra-arterial stents implanted.All of them used cerebral protection of filter devices.Results 18 self-expandable stents were successfully implanted in 14 patients.Of them,stroke ictus caused by microemboli in 2 patients ,and they recovered after treatment for 1~3 d,6 patients had transient bradycardia and hypotension.No cerebral infarction could be seen in all cases during the follow-up period.Conclusion Carotid setenting with cerebral protection devices is an effective and safe method in treating carotid stenosis,and it is helpful to reduce the neurological complication.
