神经内镜辅助锁孔手术治疗颅内动脉瘤

目的 探讨神经内镜辅助下的锁孔手术治疗颅内动脉瘤的手术效果。方法 对14例颅内动脉瘤行动脉瘤夹闭术。经眉弓或翼点锁孔开颅，手术显微镜下初步暴露动脉瘤，置入神经内镜，观察动脉瘤颈及其周围结构的局部解剖，动脉瘤夹夹闭，再次置入神经内镜了解夹闭情况。结果 14例患者均无手术并发症，未出现新的神经系统症状与体征，全部恢复良好出院。结论 应用神经内镜辅助下的锁孔手术治疗颅内动脉瘤，可充分暴露动脉瘤及周围结构的局部解剖结构，手术创伤小，手术时间缩短，手术效果明显提高。

Keyhole operation for treatment of the intracranial aneurysm with the assistant of neuroendoscope

Objective To discuss the operation effect and the role of neuroendoscope which was used to assist the keyhole approach in treatment of intracranial aneurysms Methods The keyhole surgery with the assistant of neuroendoscope was used to treat 14 cases of aneurysm After initial exposure of pterional or superciliary arch keyhole approach with the aid of microscope,the rigis endoscpe was introduced to confirm regional anatomy,including the aneurismal neck and adjacent structure After clipping,introduced again to inspect the positions of the clip and nearby structures. Results After operation,all the 14 cases were recovered without any severe complication. Conclusions There was a sufficient exposure in the visualization of the anatomy of the aneurysm and surrouding structures,the injuries of operation were relieved,the time in operation and hospital can be shortern,as well as reliable operation effect.
