Re: Quick Overview on Hydrocephalus?

One of the problems with understanding hydrocephalus is that the pathophysiology, prognosis, and treatment will vary depending on what led the patient to be hydrocephalic. Whatever the cause, hydrocephalus means that you have excess accumulation of CSF in the head, which can cause increased intracranial pressure.
Three classes of things can go wrong in the head to lead to hydrocephalus: abnormalities in absorption, abnormalities in flow, or abnormalities in formation. When you have impaired CSF flow (like in spina bifida), that's referred to as obstructive hydrocephalus. When there's no block in flow but there is a formation or absorption issue (like a brain bleed in a premie), that's communicating hydrocephalus. (Then sometimes there are elements of both communicating and obstructive.)
Cerebral shunts (like a VP shunt) used to be one of the only definitive treatments, but now there's also a procedure called endoscopic third ventriculostomy (ETV) where a tiny hole is made in the third ventricle to allow escape of CSF. ETV is often the most successful in patients with obstructive hydrocephalus and in patients who already have shunts.
Does that clear some of it up?
