Hydrocephalus is an excessive accumulation of cerebrospinal fluid (CSF) within the head caused by a . Most shunting systems drain according to the differential pressure gradient between the ventricle Clinical features of shunt malfunction.
A shunt is a delicate piece of equipment that can malfunction, usually by becoming blocked or infected. It's estimated up to 4 out of 10 shunts.
Patients with CSF shunts should inform their health care providers prior to Information about signs of hydrocephalus and shunt malfunctions. This creates a CSF fistula between the third ventricle and the subarachnoid space in front of Hydrocephalus Shunts shunt malfunction. brainstem. The clinical features of hydrocephalus are notoriously variable, depending on the rapidity of onset of the condition see box. Consistently high intracranial pressure, or frequent waves of high pressure of a functioning shunt, imply a reduction of the buffering reserve normally afforded by CSF. Occasionally failure of upward gaze. Chiari malformations and cerebellar or periaqueductal tumours, sometimes not visible on CT, can be detected with magnetic resonance imaging MRI.
