The aim of this chapter is to explain the pathology of hydrocephalus, which relates to an imbalance between the production and absorption of cerebrospinal fluid (CSF) leading to increases in intracranial pressure. Hydrocephalus has numerous causes and may be congenital or arise secondary to other neurological insults. Although our understanding of CSF dynamics is still evolving, hydrocephalus has historically been divided into obstructive (radiologically visible obstructive lesion) and communicating/nonobstructive (no radiologically visible obstructive lesion). Treatment involves CSF diversion via endoscopic third ventriculostomy of implantation of a shunt. Many children lead normal active lives with shunts in situ. Future prognosis and good health are largely determined by avoiding complications and detecting shunt malfunction early. The chapter explains the pathology, symptoms, signs, investigation, management, and operative techniques involved in the care of patients with hydrocephalus.
