Ventriculoperitoneal shunt overdrainage
Background
- Overdrainage -> tissue occluding the orifices of the proximal shunt apparatus
- As pressure increases the occluding tissue diesengages allowing drainage to resume
- Leads to cyclic incr ICP complaints that worsen when pt stands
Clinical Features
Differential Diagnosis
Ventriculoperitoneal shunt problems
- Ventriculoperitoneal shunt obstruction
