摘要
目的 :探讨前、后交通动脉瘤与Willis环血流动力学变化的关系。方法 :回顾性分析 2 0 8例数字减影脑血管造影资料。结果 :前交通动脉瘤 ,A1优势征多见 (P <0 .0 1) ;后交通动脉瘤 ,非基底动脉供血与基底动脉供血比较无明显差异 (P >0 .0 5 )。结论 :前交通动脉瘤的形成与Willis前环的血流动力学变化有关 ,后交通动脉瘤的形成与Willis后环的血流动力学变化尚无明显关系。
Objective:To research the relationship between anteroposterior aneurysms on communicating branches and the hemodynamic changes in Willis circle.Methods:Cerebral DSA findings in 208 cases were retrospectively analyzed.Results:A1 dominant signs in aneurysms group of the anterior communicating atery was more common than those in the control group( P <0.01).In aneurysms on the junction of internal carotid and posterior communicating artery,no difference was seen between aneurysms getting blood supply from basilar artery and those getting blood supply from other artery( P >0.05).Conclusion:The development of cerebral aneurysms on anterior communicating segment is related with the hemodynamic changes in the anterior circle of Willis,while hemodynamic changes in the posterior circle of Willis has no relation to the aneurysms on the ipsilateral internal carotid-posterior communicating artery junction.
