引
言
颈内动脉床突段是指位于近端硬膜环和远端硬膜环之间的一段颈内动脉主干。此段颈内动脉与前床突、近端硬膜环和远端硬膜环等关系密切。熟悉其解剖,是处理颈内动脉床突旁动脉瘤的重要基础。
一、相关骨结构
(一)蝶骨
(二)颈动脉沟
颅骨标本上面观(Rhoton,2002)。蝶骨小翼、前床突基底和视神经管顶壁已磨除。前床突内侧有沟样结构,走行颈内动脉。
(三)前床突
(四)中床突
(五)视柱
二、硬脑膜结构
(一)镰状韧带
颅底上面观(Joo,2012)。覆盖前床突上表面的硬脑膜在视神经上方延伸,形成镰状韧带(蓝色线条),覆盖前床突上表面的硬脑膜至视柱上缘,形成远端硬膜环的前部(绿色线条)。
(二)远端硬膜环和近端硬膜环
三、颈内动脉床突段
