目的　总结经额部微骨孔纵裂入路治疗前交通动脉瘤的手术方法。方法　分析 8例 (9个 )前交通动脉瘤患者的手术方法 ,经额部微骨孔纵裂入路 ,采用额部中线偏右侧游离小骨瓣 ,直径约 3cm ,沿纵裂探查至大脑镰下缘、胼胝体膝部前缘 ,显露前交通动脉 ,分离并夹闭动脉瘤颈。结果　 8例患者共发现 9个前交通动脉瘤 ,术前H H分级Ⅰ级 1例 ,Ⅱ级 7例 ,术后均获良好疗效 ,无手术致残及死亡者。结论　以额部微骨孔纵裂入路治疗前交通动脉瘤较传统的翼点入路损伤小 ,显露更直接 ,且在术中可控制双侧大脑前动脉A1段 Objective To summarize the operative methods of traffic artery aneurysms before and after the treatment of micro-fractures of the foramen per hole in the Ministry of Surgery. Methods Eight patients (9 cases) with anterior communicating artery aneurysm were enrolled in this study. They were divided into 3 groups: The lower edge of the corpus callosum front of the knee revealed the anterior communicating artery, separating and clipping the aneurysm neck. Results A total of 9 anterior communicating aneurysms were found in 8 patients. There were 1 grade H H grade and 7 grade II grade before operation. All patients received satisfactory results after operation without any maneuver and death. Conclusion Frontal micro-fractures of the anterior approach to the treatment of traffic artery aneurysm compared with the traditional pterional approach less injury, revealed more direct and intraoperative control of bilateral anterior cerebral artery segment A1
