目的探讨颈动脉支架成形术(carotid atery stentlng,CAS)治疗症状性颈动脉狭窄患者的临床疗效。方法采用颈动脉支架成形术治疗51例症状性颈内动脉狭窄患者,于围手术期进行抗血小板聚集治疗。结果全组手术成功率100%,术前平均狭窄率为79.8%,术后残余狭窄率<20%,18例保护伞中有碎屑。所有患者术后1周内症状及神经功能缺损体征有所改善。术后3例出现轻度再狭窄,l例出现重度再狭窄;未发现支架移位、缺血性脑卒中。结论颈动脉支架治疗高危症状性颈动脉狭窄创伤小,围手术期并发症少,是安全、有效的。
Objective To investigate the clinical efficacy of carotid atrium stent in patients with symptomatic carotid stenosis. Methods Carotid artery stenting was used to treat 51 patients with symptomatic internal carotid artery stenosis and received anti-platelet aggregation therapy during perioperative period. Results The success rate of the operation was 100%. The average preoperative stenosis rate was 79.8%. The residual stenosis rate was less than 20%. Debris was found in 18 cases of umbrella. All patients within 1 week after surgery symptoms and neurological deficits improved. Postoperative mild restenosis occurred in 3 cases and severe restenosis in 1 case. Stent displacement and ischemic stroke were not found. Conclusion Carotid artery stenting is safe and effective in treating high-risk symptomatic carotid artery stenosis with less perioperative complications.
