目的:探讨Liliequist膜的显微解削及其手术意义.方法:在手术显微镜下观察6例尸脑的Lilequist膜,作解剖学观测.结果:Liliequist膜是前切迹空间的网膜结构,张于鞍背和动眼神经之间,分间脑膜和中脑膜两叶,伸向后上方和后(下)方,其大小、性状及后缘附着部位均有较大个体差异,同垂体柄和后交通动脉等有纤维连系.结论:该膜有维系鞍后诸结构相对空间位置的作用,间脑膜主要分隔视交叉池与脚间池,中脑膜主要分隔脚间池与桥前池,均是重要的手术标志和界面.经幕上达到基底动脉尖或上斜坡,需经过该膜,因无血管贯穿,可较安全地切开.
Objective: To investigate the microdissection of Liliequist’s membrane and its operative significance.Methods: Six cases of Lilequist membrane were observed under an operation microscope for anatomical observation.Results: Liliequist membrane is an anterior retinal space of the omentum structure, Zhang Between the dorsal rachis and oculomotor nerves, there are large individual differences in the size, traits and posterior attachment sites between the two leaves of the division meninges and middle meninges extending above and behind the posterior (lower) side, Posterior communicating artery, etc.Conclusion: The film has the effect of maintaining the relative space position of the saddle structures, the mesencephalic space is mainly composed of the optic chiasm pool and the foot pool, Is an important surgical signs and interfaces to the basilar artery to reach the tip or the slope, the film to go through, because no vascular penetration, can be more safely cut.
