Contains two ball-valve units connected with a spring. Does not have an adjustable pressure setting. First mass-produced valve used to treat hydrocephalus in 1956. [5] Spitz-Holter Uses slits in silicone to avoid mechanical failure. [6] [7] Anti-siphon Prevents over drainage by preventing the siphon effect. The device closes when the pressure ...
The EVD is leveled to a common reference point that corresponds to the skull base, usually the tragus or external auditory meatus.The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist.
Hydrocephalus can occur due to birth defects (primary) or can develop later in life (secondary). [1] Hydrocephalus can be classified via mechanism into communicating, noncommunicating, ex vacuo, and normal pressure hydrocephalus. Diagnosis is made by physical examination and medical imaging, such as a CT scan. [1]
The surgical treatment options for hydrocephalus are, as previously mentioned, implantation of a cerebral shunt and ETV. Especially in the youngest age group (younger than two years of age) it remains uncertain what is the superior treatment modality. Currently, a large international, multicenter study is conducted to address this issue.

The underlying etiology of primary NPH has not yet been identified. Primary NPH affects adults age 40 years or older, most commonly in adults over 60. [15] Secondary NPH can affect persons of any age and occurs due to conditions such as subarachnoid hemorrhage, meningitis, brain surgery, brain radiation, or traumatic brain injury. [16]
The enlarged skull of a person with hydrocephalus, which is a symptom of the excess CSF in the ventricular system. This may be caused by aqueductal stenosis, and in some cases, it is thought that hydrocephalus will cause aqueductal stenosis. Many of the signs and symptoms of aqueductal stenosis are similar to those of hydrocephalus.
