Combined endoscopically guided third ventriculostomy with prepontine cistern placement of the ventricular catheter in a ventriculo-peritoneal shunt: technical note.

The authors present the management of non-obstructive hydrocephalus using two surgical procedures, both at the same time: first, we perform an endoscopic third ventriculostomy and second, we place the ventricular catheter of the ventriculo-peritoneal shunt in the prepontine cistern under endoscopic guidance. The main rationale is the fact that the ventricular catheter passes through multiple fixed cerebrospinal fluid circulation points in order to allow the free circulation of the cerebrospinal liquid. The authors present here details of the technique and short-term results.
