摘　　要：目的探讨采用翼点入路联合部分眶顶和额骨颧突切除(改良眶翼点入路)处理前交通动脉破裂动脉瘤的效果。方法回顾性连续纳入2013年10月至2016年10月滨州医学院附属医院神经外科收治的前交通动脉破裂动脉瘤36例,均经DSA或CT血管成像检查证实。对标准眶翼点入路的6次切割成型进行简化,采用眶翼点入路但仅去除部分眶顶而未去除眶外侧壁、蝶骨翼等骨性结构,总结前交通动脉破裂动脉瘤的临床表现、影像学资料、手术方式及手术结果。结果治疗36例前交通动脉破裂动脉瘤均采用改良眶翼点入路,术后CT复查未见明显的脑组织牵拉性损伤,出院时格拉斯哥预后评分5分25例,4分8例,3分3例,无死亡病例。随访3~24个月无再出血及复发病例。未发生眼球凹陷、眼球损伤及颅神经损伤等并发症。结论改良眶翼点入路通过切除部分眶顶和额骨颧突增加了手术操作空间,避免牵拉脑组织,明显缩短了手术操作距离,增大了对深部的观察角度,适用于处理前交通动脉动脉瘤,尤其后指向、上指向及高位前交通动脉动脉瘤。术中无骨质丢失,无需行眶顶重建;从解剖上保留了额叶直回,有利于保护术后患者认知功能。Objective To investigate the effect of using pterional approach combined with partial orbital roof and zygomatic process resection （ modified orbitopterional approach ） for the management of ruptured anterior communicating artery aneurysms. Methods From October 2013 to October 2016,36 consecutive patients with ruptured anterior communicating artery aneurysm admitted to the Department of Neurosnrgery, Binzhou Medical University Hospital were enrolled retrospectively. They were all confirmed by DSA or CT angiography. The orbitopterional approach was used, only part of the orbital roof was removed and the structures of lateral orbital wall and the wings of sphenoid bone were not removed. The clinical manifestations, imaging data, surgical methods, and surgical results of ruptured anterior communicating artery aneurysms were summarized. Results All 36 patients with anterior communicating artery aneurysm in this group were treated with the modified orbitopterional approach. There was no obvious brain retraction injury on CT scan after procedure. At the time of discharge ,the Glasgow outcome scale score was 5 in 25 cases, 4 in 8 cases, and 3 in 3 cases. No patients died. The patients were followed up for 3 to 24 months; no rebleeding and recurrence were observed. No complications occurred, such as enophthalmos, damage to the eyeballs, and cranial nerve injury. Conclusion The modified orbitopterional approach increased the operation space,avoided the distraction of brain tissue, significantly shortened the operation distance, and increased the deep observation angle through the removal of part of the orbital roof and the zygomatic process. It is suitable for the treatment of anterior communicating artery aneurysms, especially the rear direction, upper direction and high positioned aneurysms. There was no bone loss in the procedure, no need for orbital roof reconstruction. The gyri rectus was retained anatomically,and it may be helpful to protect the postoperative cognitive function of the patients.
