神经内镜辅助锁孔外科治疗颅内动脉瘤

目的：探讨神经内镜辅助锁孔外科治疗颅内动脉瘤的可行性及其意义。方法：对11例颅内动脉瘤病人，应用内镜辅助锁孔外科进行颅内动脉瘤夹闭术。经翼点或眉弓锁孔开颅，应用手术显微镜初步显露动脉瘤后，置入硬性神经内镜了解动脉瘤颈及周围结核的局部解剖，动脉瘤夹闭后再次用内镜了解夹闭情况。结果：术后11例恢复良好，无手术并发症。结论：应用神经内镜辅助锁孔外科进行颅内动脉瘤显微手术，可明显增加动脉瘤及其周围结构的可视范围，使颅内动脉瘤的手术效果有明显提高，手术时间短，术后病人恢复快，且不影响美容。

Endoscope-assisted Keyhole surgery for cerebral aneurysms

Objective To enhance visual confirmation of reginal anatomy and discuss the feasibility and the role of neuroendoscope which was used to asisst the keyhole surgery in treatment of intracranial aneurysms. Methods The neuroendoscope was used to assist the keyhole surgery to treat the intracranial aneurysm in 11 patients. After initial exposure of pterional or eyebrow keyhole approach with the aid of a microscope, the rigid endoscope was introduced to confirm the reginal anatomy, including the aneurysmal neck and adjacent stuctures. After cliping, the positions of the clipper and nearby stuctures were inspected using the neuroendoscope. Results After operation, 11 cases were recovered without any severe complication. Conclusions In all cases when the endoscope was used, there was a striking improvement in the visualisation of the anatomy of the aneurysm and surrounding structures. Furthermore, the position of the clipper and the state of the vessels leading to and from the aneurysm could be easily examined, therefor, the operative effect could be improved greatly. The time in operation and hospital can be shorten, and the cosmetic effect is excellent.
