Report on the annual meeting

CEREBROSPINAL FLUID DYNAMICS AND HYDROCEPHALUS
II. CEREBROSPINAL FLUID ABSORPTION

Hydrocephalus is a syndrome in which the balance of cerebrospinal fluid (CSF) formation and absorption is impaired resulting in an accumulation of CSF in the ventricular system and in most observed hydrocephalic cases CSF malabsorption is the causative factor.
Based upon the review of literature and more sophisticated investigations, it is believed that the principle site of CSF absorption is the arachnoid villi, however, several other structures are also indicated as lesser CSF absorptive sites. In this communication, transventricular or transependymal absorption of CSF is emphasized, particularly in hydrocephalic individuals as a subsidiary pathway of CSF when main CSF absorptive pattern is vitiated.
Physiological data from perfusion technique of CSF compartments as well as electron microscopic findings on tracer study and autoradiographic pictures are presented and discussed.
