The understanding of the anatomy of the subarachnoid cisterns and trabecular membranes is of paramount importance in the surgical treatment of pathology of the posterior fossa. Aneurysms, arteriovenous malformations, and some tumors should be approached through the subarachnoid space. The subarachnoid cisterns provide natural pathways to approach neurovascular and cranial nerve structures. The microsurgical anatomy of the infratentorial subarachnoid cisterns was studied in twenty adult brains, using the 'immersion technique'. Air was injected into the subarachnoid cisterns and brains were dissected under the operative microscope. Six main compartmental trabecular membranes were identified in the infratentorial level. They divide the subarachnoid space into six cisterns. Cisternal divisions and the disposition of the trabecular membranes were closely related to the vascular divisional patterns of the principal arteries. Thorough knowledge of the microsurgical anatomy of the subarachnoid space will aid neurosurgeons during the surgical approach of many vascular and tumoral lesions located in the posterior fossa.
了解蛛网膜下池和小梁膜的解剖结构对于后颅窝病变的外科治疗至关重要。动脉瘤、动静脉畸形和一些肿瘤应通过蛛网膜下腔进行处理。蛛网膜下池为接近神经血管和脑神经结构提供了自然通道。采用“浸没技术”，在20个成人大脑中研究了幕下蛛网膜下池的显微解剖结构。向蛛网膜下池注入空气，然后在手术显微镜下对大脑进行解剖。在幕下水平确定了六个主要的间隔小梁膜。它们将蛛网膜下腔分为六个池。池的划分和小梁膜的分布与主要动脉的血管分支模式密切相关。全面了解蛛网膜下腔的显微解剖结构将有助于神经外科医生在处理位于后颅窝的许多血管性和肿瘤性病变的手术过程中。
