摘　　要：目的探讨侧支循环开放的类型对颈内动脉(internal carotid artery,ICA)重度狭窄或闭塞患者脑血管反应性和注意网络的影响。方法将有侧支循环形成的患者分为前交通动脉(anterior communicating artery,Aco A)开放组、后交通动脉(posterior communicating artery,Pco A)开放组和眼动脉(ophthalmic artery,OA)开放组,分别检测各组的屏气指数(breath-holding index,BHI)和注意网络测试(attention network test,ANT)指标。结果 Aco A开放组患侧BHI、总平均反应时间(reaction time,RT)和执行功能优于其它两组,OA开放组的定向和执行功能较其它两组减退(P<0.05)。Aco A和Pco A开放组患侧的BHI与相应的ANT总平均RT呈负相关(P<0.01)。结论 Aco A开放患者脑血管反应性和注意网络损害的程度较Pco A和OA开放者较轻,Aco A是对于注意功能最有效的侧支循环。Objective To explore the influence of different types of collateral circulation on cerebrovascular reactivity and attention network after severe stenosis or occlusion of internal carotid artery（ ICA）. Methods Patients with collateral circulation were divided into three groups according to the type of collateral circulation： anterior communicating artery（ Aco A） group,posterior communicating artery（ Pco A） group and ophthalmic artery group（ OA）. Breath-holding index（ BHI） was obtained and attention network test（ ANT） was carried out. Results BHI values of the affected side,total average reaction time and executive control function in Aco A group were better than the other two groups. OA group performed worse on orienting and executive control function than the other two groups（ P 〈0. 05）. There were significant correlations between BHI values of the affected side and total average RT in Aco A and Pco A group（ P 〈0. 01）. Conclusion Patients with Aco A have less impairment in cerebrovascular reactivity and attention networks than Pco A and OA,therefore Aco A is the most potent collateral pathway for attention function.
