经眶锁孔入路夹闭前交通动脉瘤

目的探讨经眶锁孔入路治疗前交通动脉瘤的手术方法和治疗效果。方法回顾性分析我院2003年10月至2005年1月间采用经眶锁孔入路手术治疗前交通动脉瘤14例的临床资料,介绍经眶锁孔入路的手术方法。结果14例动脉瘤均成功夹闭。由于切下了眶上缘,手术径路的角度下移,可在较小牵拉脑的情况下抬起额底和分离纵裂间隙显露并处理病变。结论应用经眶锁孔入路手术能以更低的角度,从脑外间隙处理前交通动脉瘤,可作为前交通动脉瘤手术入路的一种选择。

Transorbital keyhole Approach to Anterior Communicating Artery Aneurysms

Objectives To explore the operative technique of clipping the anterior communicating artery aneurysms via the transorbital keyhole approach and its curative effect. Methods The clinical data of 14 patients with anterior communicating artery aneurysms treated through transorbital keyhole approach in our hospital was summarized.The operating technique is described. Results The aneurysms were succesfully clipped in all the patients. Due to the removal of superior orbital rim, a more ventral access was provided, and the anterior communicating artery complex can be exposed and controlled by and mild elevation of the orbital cortex splitting the basal aspect of the interhemispheric fissure without great tracton of the brain. Conclusions The anterior communicating artery complex can be reached via the transorbital keyhole approach from a more ventral access and extracerebral gap,which be regarded as one of operating approaches to the anterior communicating artery aneurysms.
