To establish the current viewpoint with regards to the role of arachnoid villi/granulations in cerebrospinal fluid (CSF) absorption.
Retrospective study.
Journal articles published between 1913 and 1993.
The contribution of arachnoid villi/granulations to CSF absorption from the subarachnoid space.
From available literature, it is yet to be proved that arachnoid villi/granulations are the major sites for CSF absorption from the subarachnoid space into the venous system. They may, however, play an important role in the absorption of CSF's waste products of neuronal metabolism (mainly CSF proteins) under normal physiological conditions. Furthermore, it would appear that, under pathological conditions, the absorption of CSF proteins can take place at other CSF absorption sites.
The paucity of data on the relationship between the development of arachnoid villi, the superior sagittal sinus, the superficial cortical vessels and the subarachnoid space warrants that an ontogenic study be conducted in order to achieve a better understanding of the function of arachnoid villi which is currently speculative.
确立关于蛛网膜绒毛/颗粒在脑脊液（CSF）吸收中作用的当前观点。
回顾性研究。
1913年至1993年间发表的期刊文章。
蛛网膜绒毛/颗粒对脑脊液从蛛网膜下腔吸收的贡献。
从现有文献来看，尚未证实蛛网膜绒毛/颗粒是脑脊液从蛛网膜下腔吸收进入静脉系统的主要部位。然而，在正常生理条件下，它们可能在吸收脑脊液中神经元代谢的废物（主要是脑脊液蛋白质）方面发挥重要作用。此外，在病理条件下，脑脊液蛋白质的吸收似乎可以在其他脑脊液吸收部位进行。
关于蛛网膜绒毛、上矢状窦、大脑皮质浅静脉和蛛网膜下腔之间关系的数据匮乏，这使得有必要进行一项个体发生学研究，以便更好地理解目前仍具有推测性的蛛网膜绒毛的功能。
