颅外颈动脉狭窄的血管内支架成形术

Carotid angioplasty and stenting for extracranial carotid stenosis

目的分析血管内支架成形术治疗颈动脉狭窄的安全性、有效性和短期效果。方法59例颅外颈动脉狭窄的患者采用自膨胀支架进行血管内支架成形术治疗。结果59例患者均治疗成功，其中3例双侧颈内动脉颅外段狭窄患者同期各置入2个支架使血管基本恢复正常管径，2例同侧颈内动脉颅外段狭窄患者同期连续置入2个支架使血管基本恢复正常管径。支架成形术后颈动脉平均狭窄程度从（79±10）%降低到（11±7）％。结论颅外颈动脉狭窄的血管内支架成形术是一种安全、有效、简单的方法，短期效果令人满意。

Objective To evaluate the safety and short-term outcome of carotid angioplasty and stenfing for extracranial carotid stenosis. Method Fifty-nine cases of extracranial carotid stenosis were treated by carotid angioplasty and stenting. Results All procedures were performed successfully. Among the total, 3 cases were with both sides of extracranial arterial stenosis and 2 with homolateral extracranial arterial stenosis, who were deployed 2 stents respectively. The average stenosis rate was reduced from （79±10）% before treatment to （ 11±7）% after carotid angioplasty and stenting. Conclusion Carotid angioplasty and stenting for extracranial stenosis is a safe and effective method with considerable satisfactory short-term outcome.
