Traumatic intracranial aneurysms are rare, usually occur as a result of traffic accidents, and are associated with high rates of morbidity and mortality. A 12-year-old boy was admitted for treatment of cerebral hemorrhage in the left frontal lobe, 3 months after a traffic accident. Angiography revealed an intracranial aneurysm of the distal part of the azygos anterior cerebral artery (ACA). The maximum size of this aneurysm was 9.5 mm. Coil embolization was successfully performed with preservation of the parent arteries. Angiography performed at the 4-year follow-up examination revealed no abnormalities. The present case showed that primary coiling may allow aneurysm occlusion along with parent vessel preservation in selected cases of traumatic intracranial aneurysm of the distal part of the azygos ACA.
创伤性颅内动脉瘤较为罕见，通常由交通事故导致，且发病率和死亡率较高。一名12岁男孩在交通事故3个月后因左侧额叶脑出血入院治疗。血管造影显示奇静脉大脑前动脉（ACA）远端存在颅内动脉瘤。该动脉瘤最大尺寸为9.5毫米。成功进行了弹簧圈栓塞术，同时保留了载瘤动脉。4年随访血管造影显示无异常。本病例表明，对于奇静脉ACA远端创伤性颅内动脉瘤的某些病例，初次弹簧圈栓塞术可实现动脉瘤闭塞并保留载瘤血管。
