A clear and thorough understanding of the neuroanatomical structures of the subarachnoid cisterns is important because they provide natural pathways to intracranial arteries, veins, and nerves during microvascular procedures without disturbing surrounding important brain structures. Using a surgical microscope, we examined the microsurgical anatomy of the trabecular membranes and subarachnoid cisterns in 20 adult cadaver brains. The brains were immersed in Ringer's solution and air was injected into the subarachnoid cisterns while the brains remained submerged in solution. We identified seven trabecular membranes that limit six cisterns. We specifically looked at the anatomical relationship between the trabecular membranes and cisterns and their corresponding vessels and cranial nerves. The cistern divisions and the dispositions of trabecular membranes were closely related to the vascular division patterns of the principal brain arteries.
清楚而全面地了解蛛网膜下池的神经解剖结构很重要，因为在微血管手术中，它们为颅内动脉、静脉和神经提供了天然通道，而不会干扰周围重要的脑结构。我们使用手术显微镜检查了20个成人尸体脑内小梁膜和蛛网膜下池的显微外科解剖结构。将这些脑浸泡在林格氏溶液中，在脑仍浸没于溶液时向蛛网膜下池注入空气。我们识别出了七个限制六个脑池的小梁膜。我们特别研究了小梁膜与脑池及其相应血管和颅神经之间的解剖关系。脑池的划分和小梁膜的分布与主要脑动脉的血管分支模式密切相关。
