Arachnoid Villi and Granulations

  • Conference paper

Abstract

Although as early as 1900 CUSHING believed that wide, valve-like passages linked the meningeal spaces to the adjacent veins, the work of WEED persuaded him that these passages did not exist (1,2). The concept that the arachnoid villus is a blind diverticulum of arachnoid that projects into a venous channel, and that it serves as a membrane through which cerebrospinal fluid passes into the blood stream was then widely accepted, WELCH and FRIEDMAN (3) reported in 1960 that the arachnoid villus of the monkey forms a labyrinth of small tubules that establish open connections between the subarachnoid space and the venous blood and they felt that these tubules had a valve-like function. This would imply a pressure-dependent passive mechanism for the passage of cerebrospinal fluid through the arachnoid villus.
