血管内支架成型术治疗颈动脉狭窄21例

目的探讨血管内支架成型术治疗颈动脉狭窄的临床效果和安全性。方法对21例颈动脉狭窄患者,先行血管造影,然后根据血管狭窄情况,选择合适自膨式支架跨过狭窄部位,将支架送至预想的位置释放,覆盖狭窄部位。结果治疗狭窄动脉21支,狭窄程度均明显改善,狭窄程度由原来的(78.94±12.8)%下降至(3.19±3.04)%,无死亡病例,术后患者症状均明显改善,围术期无并发症。随访1~12个月,颈动脉超声检查治疗血管无再狭窄。结论只要适应证选择正确,围术期处理得当,血管内支架成型术治疗颈动脉狭窄,不仅临床效果好,而且安全性高。

Angioplasty and Stenting for 21 Cases of Symptomatic Carotid Artery Stenosis

Objective To analyze the treating result of symptomatic carotid artery stenosis with angioplasty and stenting, was well as their safety. Methods A total of 21 patients with symptomatic carotid artery stenosis were treated with angioplasty and stenting between July 2006 and December 2007. Results As a result, 21 stenosed branches of arteries were treated. The stenosis was decreased from 78.94%±12.8% to 3.19%±3.04% (of diameter). No death occurred. The symptoms or signs (complaint) were improved excellently after angioplasty and stenting, and no one experienced procedure-related complication. The patients were followed up for 1-11 months, and no restenosis was found by ultrasonic examination of carotid artery. Conclusion The therapy with angioplasty and stenting is safe and valid for symptomatic carotid artery stenosis. But the selection for indications, the special treatment during operation and the skillful technique were the keys to success.
