颈部动脉支架置入术后双联抗血小板治疗:多久合适?

目的 观察颈部动脉支架置入术后双联抗血小板治疗不同时间的效果,探讨合理的双联抗血小板治疗时间.方法 66例颈部动脉有症状狭窄＞50%或无症状狭窄＞70%的患者在局麻下行支架置入术,术后随机分为双联抗血小板治疗(阿司匹林+氯吡格雷)1个月组和3个月组,然后长期服用阿司匹林.前瞻性观察并发症、血管事件以及再狭窄发生率.结果 术后6～36个月,两组均无血管事件和死亡,并发症和再狭窄(9%对6%)发生率无显著差异(P=0.642).结论 颈部动脉支架置入术后阿司匹林+氯吡格雷联合治疗1个月与3个月的疗效并无显著差异,1个月的双联抗血小板治疗可能比较合适,但还需大规模随机对照试验证实.

Abstract：

Objective To observe the effects of dual antiplatelet therapy at different time after cervical artery stenting and to investigate the reasonable time for dual antiplatelet therapy. Methods Sixty-six patients with symptomatic cervical artery artery stenosis ＞50% or asymptomatic stenosis ＞70% performed stenting under local anesthesia. They were randomly allocated into dual antiplatelet therapy (aspirin + clopidogrel) for 1 month and for 3-month groups after procedure, and then they began to take aspirin for a long time. The complications, vascular events, and the incidence of restenosis were observed respectively. Results There were no vascular events and death in both groups from 6 to 36 months after procedure. There was no significant difference in the incidence of complication and restenosis (9% vs. 6%, P = 0. 642). Conclusions There was no significant difference in the efficacy of aspirin + clopidogrel treatment after cervical artery stenting between 1 month and 3 months. One month dual antiplatelet therapy may be appropriate, but large-scale randomized controlled trials are needed to confirm it.
