微骨窗入路在颅内动脉瘤手术中的应用

目的探讨微骨窗入路（锁孔入路）治疗颅内动脉瘤的手术技术和治疗效果。方法采用微骨窗入路对56例58个颅内动脉瘤施行直接手术夹闭。56例动脉瘤中前交通动脉瘤23例,颈内-后交通动脉瘤29例（双侧动脉瘤2例）,颈内动脉瘤4例。手术经眶上入路22例,翼点入路18例,眉弓切121经眶入路16例。对33例患者使用神经内镜辅助手术。结果对56例动脉瘤的手术,成功地夹闭58个动脉瘤。对2例双侧后交通动脉瘤均经一侧入路一次夹闭。术后37例患者经复查脑血管造影,证实动脉瘤消失。无手术死亡病例。未发生与手术入路相关的并发症。结论微骨窗入路开颅治疗颅内动脉瘤在技术上是可行的。不仅减少了手术创伤,缩短了手术时间,治疗效果也理想。

Application of keyhole approach in operation of intracranial aneurysms

Objective To explore the operative technique and evaluate the effect of intracranial aneurysms via keyhole approach. Methods Fifty-six intracranial aneurysm patients, 23 with anterior communicating artery (AcomA) aneurysm, 29 with posterior communicating artery (PcomA) aneurysm, and 4 with internal carotid artery-posterior communicating artery aneurysm, totally with 58 lesions, were treated by microsurgery, via supraorbital keyhole approach in 22 cases, pterional approach in 18,and transorbital approach in 16. Adjuvant endoscopy was used in 33 patients. Results Fifty-eight lesions of aneurysm were clipped in all the patients and no one died. No approach-related severe complication occurred. Bilateral PcomA aneurysms in 2 cases were clipped via unilateral keyhole approach. Conclusion It is workable to treat intracranial aneurysms via keyhole approach. Keyhole approach not only reduces the operation-related trauma and shorten the operation time, but also obtains ideal results.
