* '''[[Shunting]]''':It involves the placement of a [[catheter|ventricular catheter]] (a tube made of [[silastic]]), into the [[ventricle (brain)|cerebral ventricles]] to bypass the flow obstruction/malfunctioning [[arachnoid villi|arachnoidal granulations]] and drain the excess fluid into other body cavities, from where it can be resorbed.Types of shunts done are

**[[Shunt]]: Shunting needs the placement of a [[catheter|ventricular catheter]].
* '''[[Endoscopic third ventriculostomy]]''' :  A surgically created opening in the floor of the third ventricle allows the CSF to flow directly to the basal cisterns, thereby shortcutting any obstruction, as in aqueductal stenosis. This may or may not be appropriate based on individual anatomy. Internal hydrocephalus can be successfully treated by placing a drainage tube (shunt) between the brain ventricles and abdominal cavity to eliminate the high internal pressures. There is some risk of [[infection]] being introduced into the brain through these shunts, however, and the shunts must be replaced as the person grows. A subarachnoid hemorrhage may block the return of CSF to the circulation. If CSF accumulates in the [[subarachnoid space]], the condition is called '''external hydrocephalus'''. In this condition, pressure is applied to the brain externally, compressing neural tissues and causing brain damage. Thus resulting to a much further damage of the brain tissue and leading to necrotization

Overview

The mainstay of treatment for hydrocephalus is medical therapy. Surgery is usually reserved for patients with either increased ICP, stroke and subarachnoid hemorrhage. The surgical methods of hydrocephalus are Decompressive crainectomy with shunting is the main surgical method use in hydrocephalus. Shunting involves the placement of a ventricular catheter. Shunt is the tube placed in cerebral ventricles to bypass the flow of malfunctioning arachnoidal granulations. Shunt, drains out the excess fluid into other body cavities, which is resorbed from there.

Surgery

  • The surgical treatment is given below:[1][2][3][4][5]
  • Hydrocephalus treatment is surgical.
  • For a detailed approach on performing cerebral shunt watch the video below:

Shunt complications

Possible complications include

  • Resistance to traditional analgesic pharmacological therapy may also be sign of shunt overdrainage or failure.
  • Diagnosis of the particular complication usually depends on when the symptoms appear.
