Abstract

Postsurgery intracranial air usually diminishes, presumably merging with cerebrospinal fluid (CSF) and venous circulation. Our study presents two transsphenoidal surgery cases, highlighting potential air absorption by arachnoid granulation (AG)-an underexplored phenomenon. AG has long been deemed pivotal for CSF absorption, but recent perspectives suggest a significant role in waste clearance, neuroinflammation, and neuroimmunity. These cases may stimulate renewed research on the multifaceted role of AG in neurofluid dynamics and potentially elucidate further AG functions.

摘要

术后颅内积气通常会减少，推测是与脑脊液（CSF）和静脉循环融合。我们的研究展示了两例经蝶窦手术病例，突出了蛛网膜颗粒（AG）吸收气体的潜在现象——这是一个尚未充分探索的现象。长期以来，AG一直被认为对脑脊液吸收至关重要，但最近的观点表明它在废物清除、神经炎症和神经免疫方面也发挥着重要作用。这些病例可能会激发对AG在神经流体动力学中多方面作用的新研究，并有可能进一步阐明AG的功能。
