摘要
目的分析颈动脉狭窄或闭塞的侧支循环类型及其与认知障碍的关系。方法选取50例患者分为无侧支代偿组(25例)和有侧支代偿组(25例),均使用经颅多普勒(TCD)评估有侧支循环患者侧支循环类型,另选取50例健康人群为对照组,与试验组一同进行脑血流量(CBFV)情况评估与成人韦克斯勒智力量表评估认知水平。结果出现侧支循环的动脉数随狭窄严重程度而上升,试验组两组患者比较,CBFV差异有统计学意义,且无论有无侧支循环,试验组与对照组的CBFV差异也有显著差异,成人韦克斯勒智力量表测试显示,试验组正常率为12%,对照组为100%,两组有统计学差异。结论颈动脉狭窄或闭塞侧支循环及类型是脑血流量减少的因素之一,并与临床出现认知障碍相关。
Objective To analyze the type of carotid artery stenosis or occlusion and cognitive disorder. Methods 50 patients were divided into two groups：carotid artery stenosis with/without collateral circulation.The type of collateral circulation were assessed by transcranial Doppler, Choose another 50 patients as a control group,test all patients in adult Wechsler intelligence scale and analyses.Results The number of collateral circulation in the arteries with stenosis severityincreased.Compare the two groups, CBFV difference was statistically significant, and with or without collateral circulation, there were significant differences in CBFV differences of the experimental group and control group. The adult Wechsler Intelligence Scale test, normaltest group was 12%, and 100% in the control group, were signifi- cantly different in the twogroups.Conclusion The type of collateral circulation in carotid artery stenosis has relation to the cerebral blood flow injuries,and leads to cognitive disorder.
