目的:探讨Willis环形态与再发缺血性脑卒中的关系。方法:50例再发缺血性脑卒中患者,比较Willis环完整与不完整组的脑卒中间隔时间及1 a内与1 a以上再发脑梗死患者中Willis环不完整检出率。结果:Willis环不完整组再发脑梗死时间短于完整组(P<0.001)。1 a内再发脑梗死患者Willis环不完整检出率高于1 a以上者(P<0.001)。结论:Willis环不完整与快速再发脑梗死相关。
Objective: To investigate the relationship between Willis ring morphology and recurrent ischemic stroke. Methods: Fifty patients with recurrent ischemic stroke were enrolled in this study. The intervals of stroke in incomplete and incomplete Willis rings and the incomplete detection of Willis rings in patients with recurrent cerebral infarction more than 1 year within 1 year were compared. Results: Willis ring incomplete group of recurrent cerebral infarction time shorter than the complete group (P <0.001). The incomplete detection rate of Willis ring in patients with recurrent cerebral infarction within 1 year was higher than 1 year (P <0.001). Conclusion: The incomplete Willis ring is associated with rapid recurrent cerebral infarction.
