摘要
目的探讨颈内动脉狭窄或闭塞结局与Willis环的解剖变异的关系。方法64排螺旋CT脑血管成像诊断为重度颈内动脉狭窄或闭塞患者20例,单侧和双侧各10例,根据其临床表现分为大面积脑梗死组和非大面积脑梗死组,分析其Willis环变异情况。结果颈内动脉狭窄或闭塞组发生大面积脑梗死者前、后循环完整率分别为37.5%(3/8)、12.5%(1/8),明显低于非大面积脑梗死患者,两组差异有统计学意义(P<0.05)。结论颈内动脉狭窄或闭塞的结局与Willis环的变异密切相关。
Objective To investigate the relationship between anatomic variation of the circle of Willis (CW) and end-results of internal carotid artery (ICA) stenosis or occlusion. Methods Twenty patients harboring internal carotid artery stenosis or occlusion demonstrated by 64-slice CT Angiography (CTA) were involved in this study, both unilateral and bilateral were ten eases. They were divided into 2 groups :large area of cerebral infarction group( n = 8) and no-cerebral infarction group ( n= 12) according to the imaging manifestation. Results In infarction group, only 37.5% (3/8) cases demonstrated a complete anterior circulation of the circle and 12.5% (1/8) cases demonstrated a complete posterior circulation of the circle, which was obvious lower than those in no-infarction group. Conclusion End-results of internal carotid artery (1CA) stenosis or occlusion maybe closely relate with anatomic variation of the CW.
