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 increased ICP complaints that worsen when patient stands
    • Newer valve devices with antisiphon features make this less common
