Background
- Most common type of shunt malfunction
- Usually occurs at proximal tubing, followed by distal tubing followed by valve chamber
- Proximal obstructions usually occurs within first years of insertion
- Distal obstruction usually occurs only with shunts in place for >2yr
Causes
- Proximal obstruction
- Tissue debris
- Choroid plexus
- Clot
- Infection
- Catheter-tip migration
- Localized immune response to the tubing
- Distal obstruction
- Kinking or disconnection of the tube
- Pseudocyst formation
- Infection
