Abstract

INTRODUCTION

Brain is suspended in cerebrospinal fluid (CSF)-filled subarachnoid space by subarachnoid trabeculae (SAT), which are collagen-reinforced columns stretching between the arachnoid and pia maters. Much neuroanatomic research has been focused on the subarachnoid cisterns and arachnoid matter but reported data on the SAT are limited. This study provides a comprehensive review of subarachnoid trabeculae, including their embryology, histology, morphologic variations, and surgical significance.

METHODS

A literature search was conducted with no date restrictions in PubMed, Medline, EMBASE, Wiley Online Library, Cochrane, and Research Gate. Terms for the search included but were not limited to subarachnoid trabeculae, subarachnoid trabecular membrane, arachnoid mater, subarachnoid trabeculae embryology, subarachnoid trabeculae histology, and morphology. Articles with a high likelihood of bias, any study published in nonpopular journals (not indexed in PubMed or MEDLINE), and studies with conflicting data were excluded.

RESULTS

A total of 1113 articles were retrieved. Of these, 110 articles including 19 book chapters, 58 original articles, 31 review articles, and 2 case reports met our inclusion criteria.

CONCLUSIONS

SAT provide mechanical support to neurovascular structures through cell-to-cell interconnections and specific junctions between the pia and arachnoid maters. They vary widely in appearance and configuration among different parts of the brain. The complex network of SAT is inhomogeneous and mainly located in the vicinity of blood vessels. Microsurgical procedures should be performed with great care, and sharp rather than blunt trabecular dissection is recommended because of the close relationship to neurovascular structures. The significance of SAT for cerebrospinal fluid flow and hydrocephalus is to be determined.

摘要

引言

脑通过蛛网膜小梁（SAT）悬浮于充满脑脊液（CSF）的蛛网膜下腔，蛛网膜小梁是在蛛网膜和软脑膜之间延伸的胶原强化柱。许多神经解剖学研究聚焦于蛛网膜下池和蛛网膜，但关于蛛网膜小梁的报道数据有限。本研究对蛛网膜小梁进行了全面综述，包括其胚胎学、组织学、形态学变异及手术意义。

方法

在PubMed、Medline、EMBASE、Wiley Online Library、Cochrane和Research Gate上进行无日期限制的文献检索。检索词包括但不限于蛛网膜小梁、蛛网膜小梁膜、蛛网膜、蛛网膜小梁胚胎学、蛛网膜小梁组织学和形态学。排除有高度偏倚可能性的文章、任何发表在非知名期刊（未被PubMed或MEDLINE索引）上的研究以及数据相互矛盾的研究。
