单侧颅底动脉瘤开颅夹闭术通常是选择同侧入路,但有些病例为多发性且为双侧,采用一侧开颅能同时夹闭同侧及对侧的动脉瘤,不仅可以降低手术费用,减少二次开颅的危险,而且还可以避免在等待二次手术过程中动脉瘤破裂的危险;还有一些动脉瘤由于生长部位和突出方向的原因,采用同侧入路反而不容易暴露瘤颈,而采用对侧入路可使瘤颈暴露充分,利于夹闭。 Unilateral cranial aneurysm craniotomy closed usually choose the ipsilateral approach, but in some cases multiple and bilateral, the use of one side of the craniotomy can simultaneously clip ipsilateral and contralateral aneurysms, not only can Reduce the cost of surgery and reduce the risk of second craniotomy, but also to avoid the risk of aneurysm rupture during the waiting for the second surgery; some aneurysms due to the growth of the site and highlight the direction of the reason, the use of ipsilateral approach instead Easily expose the neck, and the use of the contralateral approach allows full neck tumor, which will help clamp.
