The azygos anterior cerebral artery (ACA) is a rare anatomical anomaly. Clipping surgery has been conducted in approximately 30 reported cases because it is frequently associated with aneurysms. However, few cases in which coil embolization was performed have been reported. We report three cases of coil embolization for distal ACA aneurysms with distal azygos ACA at our institution in 7 years. All patients were over 65-year-old women with saccular aneurysms larger than 7 mm; two with subarachnoid hemorrhage and one with an unruptured aneurysm. No patient had surgical complications associated with coil embolization. Coil embolization is also useful for large aneurysms in the distal azygos ACA, and its indication for treatment could be broadened.
奇静脉大脑前动脉（ACA）是一种罕见的解剖异常。约有 30 例报道的病例进行了夹闭手术，因为它常与动脉瘤有关。然而，报道的进行线圈栓塞的病例很少。我们报告了 7 年内我院 3 例因远端 ACA 动脉瘤伴远端奇静脉 ACA 而进行线圈栓塞的病例。所有患者均为 65 岁以上女性，囊状动脉瘤大于 7 毫米；2 例蛛网膜下腔出血，1 例未破裂动脉瘤。无患者发生与线圈栓塞相关的手术并发症。线圈栓塞对于远端奇静脉 ACA 中的大动脉瘤也很有用，其治疗适应证可以扩大。
