Ventriculoscope-guided ventriculoperitoneal shunt and shunt revision. Technical note.

A new small, flexible fiberoptic ventriculoscope for the accurate positioning of a ventricular catheter tip has been developed. The technique for ventriculoscope-guided ventriculoperitoneal shunt and shunt revision is described. The ventricular catheter can easily be positioned away from the choroid plexus. Choroid plexus adhering to the shunt tube can be coagulated during shunt revision. This procedure can thus prevent an obstruction of the ventricular catheter by an adherent choroid plexus.
