"History and etymology"
"Walter Dandy first attempted to classify hydrocephalus into communicating and non-communicating (obstructive) types in 1913 by injecting dyes into experimental animals and later children with hydrocephalus 6. If the dye can be retrieved by lumbar puncture from the spinal subarachnoid space, it would mean the hydrocephalus is "communicating". If the dye cannot be retrieved, it would mean the hydrocephalus is "non-communicating" or "obstructive". Although it is widely believed that defective absorption of CSF at the arachnoid granulation is the cause of communicating hydrocephalus; however, obstruction between spinal subarachnoid space and basal cisterns or between the basal cisterns and arachnoid villi are more common. In 1960, American neurosurgeon Joseph Ransohoff II recognised this misconception and tried to reclassify hydrocephalus into "intraventricular obstructive" and "extraventricular obstructive". However, his work was largely ignored 6."
