The relationship between the afferent artery and the site of aneurysmal neck and hemodynamics in the anterior part of the circle of Willis was investigated from surgical and angiographic findings in 213 patients with anterior communicating artery aneurysms. An afferent artery was limited to the dominant A1 in about 95% of them. The neck of an aneurysm was more than three times greater at the bifurcation of the dominant A1 and the anterior communicating artery than at the bifurcation of the non-dominant A1 and the anterior communicating artery.
通过对213例前交通动脉动脉瘤患者的手术和血管造影结果进行研究，探讨了 Willis 环前部传入动脉与动脉瘤颈部位置及血流动力学之间的关系。在大约95%的患者中，传入动脉局限于优势A1。优势A1与前交通动脉分叉处的动脉瘤颈部比非优势A1与前交通动脉分叉处的动脉瘤颈部大三倍以上。
