Simultaneous ventriculoperitoneal shunt removal and endoscopic third ventriculostomy for three patients previously treated for intracranial germ cell tumors more than 20 years ago

摘要

Here, we present the cases of three patients who underwent simultaneous removal of malfunctioning VPSs and ETV, more than 20 years (range 20-27 years) after initial treatment for IGCT and relevant obstructive hydrocephalus. Despite a relatively long shunt dependency, their obstructive hydrocephalus was well-managed by ETV, probably because CSF absorptive capacity remained intact after IGCT ablation by radio-chemotherapy.
