一期锁孔手术治疗大脑前循环多发动脉瘤

目的 总结锁孔技术在大脑前循环多发动脉瘤一期手术中的应用经验。方法 回顾性分析采用一期锁孔手术治疗的26例（56个动脉瘤）大脑前循环多发动脉瘤的临床资料。一侧多发动脉瘤19例，采用一侧额纹切口，经锁孔手术夹闭动脉瘤；两侧多发动脉瘤7例，采用双侧额纹切口，经锁孔手术夹闭动脉瘤。结果 26例无死亡，无残疾。56个动脉瘤，夹闭54个，筋膜包裹2个。26例术后随访6个月~10年，均健康生活和工作。结论 一期手术、一个切口、一次性锁孔手术治疗单侧或双侧颅内前循环多发动脉瘤是可行的，效果良好。

One-stage microsurgery via keyhole approach for multiple intracranial aneurysms of the cerebral anterior circulation

Objective To summarize the experience in treating the multiple intracranial aneurysms of the cerebral anterior circulation by the one-stage microsurgery via keyhole approach. Methods Twenty-six patients with 56 multiple intracranial anterior circulation aneurysms received one-stage surgery via keyhole approach. The one-stage surgery via the frontal incision keyhole approach were performed in 19 patients with unilateral multiple aneurysms and the surgery via bilateral frontal incision approach were performed in 7 patients with bilateral multiple aneurysms in order to clip the aneurysms. Results There was no death in all the patients. Of 56 aneurysms, 54 were surgically clipped and 2 were wrapped. The foolow-up ranging from 6 months to 10 years showed that all 26 patients healthyly lived and worked. Conclusion Compared with the traditional craniotomy, the one-stage surgery via keyhole approach for the multiple intracranial aneurysms of the anterior circulation has the advantages including short operative time, less operative side-injury and better effects.
