【摘要】 目的探讨颈动脉支架成形术治疗颈动脉狭窄的可行性及安全性。方法本组28例患者,在球囊扩张及支架释放过程中,全部使用保护伞,并对颈动脉狭窄程度>70%的13例患者进行预扩张,扩张后根据狭窄长度置入自膨式支架,未扩张的15例患者直接置入自膨式支架,其中有2例未扩张的患者,支架释放后未完全膨胀,但血流通畅。结果支架置入成功率100%,未出现脑出血、脑梗死等严重并发症。支架置入后,支架膨胀良好,血流通畅,患者临床症状得到明显改善。结论颈动脉支架置入治疗颈动脉狭窄是一种新的治疗方法 ,亦能代替经典颈动脉内膜剥离术,并对颈动脉狭窄引起的卒中的预防和治疗发挥重要作用。更多还原

【Abstract】 Objective To evaluate the feasibility and safety of the treatment of carotid artery stenosis with carotid artery stenting.Methods This study included 28 patients,which were divided into two groups according to the degree of their carotid artery stenosis.One group included 13 patients,whose carotid artery stenosis degree exceeded 70%,were implemented pre-inflation before the placement of self-expandable microstent;the other 15 patients were embedded directly with self-expandable microstent.The technique of preventive filter devices were used to all of cases during the course of balloon inflated and stent released.Results Stent placement was technically succeeded and no significant complications occurred,such as cerebral hemorrhage,cerebral ischemic stroke and so on in all the 28 patients.After they were placed,the stents were well expanded,cerebral blood flow improved,and patients’ symptoms alleviated.Conclusion In view of therapeutic efficacy and complications,carotid artery stenting has a significant advantage over classical technique of carotid endarterectomy.更多还原
