Four cases of aneurysms associated with a fenestrated anterior cerebral artery are presented. The combination of aneurysms and fenestration of the anterior cerebral artery is rare, and nine cases including ours have been reported. In all cases fenestrations were found within the distal two-thirds of the horizontal portion of the anterior cerebral artery. It may be presumed that fenestration of the anterior cerebral artery is the remnant of the plexiform anastomosis in the fetal stage, especially between the anterior cerebral artery and the primitive olfactory artery.
本文报告了4例与大脑前动脉开窗相关的动脉瘤病例。动脉瘤与大脑前动脉开窗同时存在的情况较为罕见，包括我们的病例在内，此前已报道过9例。所有病例中，开窗均位于大脑前动脉水平段远端的三分之二范围内。可以推测，大脑前动脉开窗是胎儿期丛状吻合的遗迹，特别是大脑前动脉与原始嗅动脉之间的吻合。
