颈动脉狭窄的支架治疗

目的:分析探讨颈动脉支架成形术治疗颈动脉狭窄的安全性。方法:本组34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大于70%的16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18例患者直接置入自膨式支架,其中有3例未扩张的患者,支架释放后未完全膨胀,但狭窄的直径超过了80%,血流通畅,未进行后扩张。结果:支架置入成功率100%,无1例患者出现脑出血、脑梗塞等严重并发症,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了重要作用。

Threatment of carotid artery stenosis with carotid artery stenting

Objective:To evaluate the feasibility and safety of the treatment of carotid artery stenosis with carotid artery stenting.Methods:This study included 34 patients, which were divided into two groups according to the degree of their carotid artery stenosis. One group included 18 patients, whose carotid artery stenosis degree exceeded 70%, that were implemented pre-inflation before the placement of self-expandable microstent; the other 18 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, ect, in all the 34 patients. After they were placed, the stents were well expanded, cerebral blood flow improved, and patients' symptoms alleviated. Conclusion:In view of therapeatic efficacy and complications, carotid artery stenting has a significant advantage over classical technique of carotid endarterectomy.
