Background:
Endoscopic surgery assisted by a navigation system has greatly aided treatment of infected multilocular hydrocephalus, especially in children.
Case Report:
We describe a 2-year-old boy with multilocular hydrocephalus caused by repeated shunt infection, presenting with fever and vomiting. Magnetic resonance images (MRI) showed extraventricular cysts and severe ventricular deformity. There were three ventriculoperitoneal shunts and one residual ventricular catheter. With a flexible endoscope, we fenestrated the wall of extraventricular cysts and removed the residual catheter. We then used a rigid endoscope to fenestrate ventricular components. Both procedures were guided by electromagnetic (EM) navigation, and hydrocephalus was controlled with one ventricular catheter.
Conclusion:
We have successfully treated a case suffered from infected multilocular hydrocephalus in infants using rigid and flexible endoscopes combined with EM navigation.
