Fenestration in A1 segment of anterior cerebral artery is a rare entity. Treatment of aneurysms derived from a fenestrated artery may be more challenging because the fenestrations provide specific difficulties. A thorough radiologic work-up driven by high clinical suspicion is needed. Endovascular treatment, although it has been tried only once, appears to be the treatment of choice. We successfully treated 2 cases using endovascular techniques and can conclude that endovascular treatment is a safe and effective treatment of aneurysms associated with this rare variation in the A1 segment of ACA.
大脑前动脉 A1 段开窗是一种罕见的现象。起源于开窗动脉的动脉瘤的治疗可能更具挑战性，因为这些开窗会带来一些特殊的困难。需要高度怀疑临床症状，并进行彻底的影像学检查。虽然曾经尝试过血管内治疗，但似乎是首选治疗方法。我们使用血管内技术成功治疗了 2 例，结论是血管内治疗是治疗与大脑前动脉 A1 段这种罕见变异相关的动脉瘤的一种安全有效的方法。
