基底动脉分叉区动脉瘤位置深,术野狭窄,兼有丘脑穿支动脉及颅神经穿行其间,故在该区域手术极具挑战性。术野的充分显露较困难,是造成此类手术困难的主要原因。颞前经海绵窦入路通过磨除前床突,移动颈内动脉(ICA),切开海绵窦顶壁并松解动眼神经,磨除部分后床突及鞍背及上斜坡的骨质,扩大了颈内动脉-动眼神经三角,提供了一个到达基底动脉分叉区的安全、有效的手术通道。因此,值得广大神经外科医生掌握。
Basilar artery bifurcation aneurysm location, narrow surgical field, both traumatic perforating artery and cranial nerve during the intermission, so the surgery in the region is extremely challenging. Difficult to fully reveal the operative field is the main reason for such surgical difficulties. Temporal anterior cavernous sinus approach through the removal of the anterior segment of the bed, move the internal carotid artery (ICA), incision cavernous sinus top and loosen the oculomotor nerve, remove part of the posterior floor and saddle back and the slope of the bone , Expanding the internal carotid artery - oculomotor triangle, providing a safe and effective surgical access to the bifurcation of the basilar artery. Therefore, it is worth the majority of neurosurgeons to master.
