Ventriculostomy involves creating a small hole in the lower part of the brain. It is generally performed using an endoscope. Although it is successful in adults but its success rate in children below 6 months is usually less. A trial is generally performed before the actual surgery to confirm the suitability of the treatment.
In this procedure, a thin tube called endoscope having a light source and optic system is introduced into the ventricles through brain and skull. A camera is attached to the outer end of the ventricular endoscope. The camera is guided into the ventricle through brain. The light source of endoscope helps in illuminating inside the lateral ventricles. The optic system is useful for reaching back to the high definition video camera. The endoscope is then operated from the lateral ventricle to the third ventricle. This creates a hole in the bottom of the brain. Thus any hindrance to the CSF outflow is neglected. An Ommaya reservoir is sometimes inserted after removal of endoscope. This is done to drain off the CSF in response to closure of ventriculostomy. This also provides testing of CSF circulation.
