Surgery
Shunting: It involves the placement of a ventricular catheter (a tube made ofsilastic), into the cerebral ventricles to bypass the flow obstruction/malfunctioning arachnoidal granulations and drain the excess fluid into other body cavities, from where it can be resorbed. Most shunts drain the fluid into the peritoneal cavity (ventriculo-peritoneal shunt), but alternative sites include the right atrium (ventriculo-atrial shunt), pleural cavity (ventriculo-pleural shunt), and gallbladderThere is some risk of infection being introduced into the brain through these shunts, however, and the shunts must be replaced as the person grows.More recently developed technologies using advanced imaging as well as endoscopic operative techniques have improved the ability of surgeons to place catheters in the ventricles of patients with IIH who do not have ventricular enlargement. [1]
Craniotomies: Holes drilled in the skull to remove intracranial hematomas or relieve pressure from parts of the brain.[2] As raised ICP's may be caused by the presence of a mass, removal of this via craniotomy will decrease raised ICP's.
Optic nerve sheath fenestration:Optic nerve sheath fenestration is a procedure that is advocated for the treatment of certain types of optic nerve dysfunction associated with progressive decline in visual function. Optic nerve sheath fenestration (ONSF) can stabilize or improve visual loss due to papilledema in IIH However, it may fail at any time after surgery. Patients with PTC need to be followed up routinely with automated perimetry to detect deterioration of visual function.[3]
