Abstract:
Shunt malfunction is the most common cause of ventriculoperitoneal shunt failure. In literature, occlusion of the tube with brain parenchyma, choroid plexus, blood, and proteinaceous debris has been suggested as a mechanism of obstruction. We herein report a case of shunt malfunction without any identifiable occlusion. Our case findings suggest that unapparent abdominal pathology, including inflammation and fibrosis, should be considered when treating shunt failures.
Insights
Ventriculoperitoneal shunt malfunction can occur without tube blockage. Unseen abdominal issues like inflammation and fibrosis may cause shunt failures, requiring consideration during treatment.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Gastroenterology
Background:
- Shunt malfunction is the leading cause of ventriculoperitoneal shunt failure.
- Commonly identified obstruction mechanisms include brain parenchyma, choroid plexus, blood, and proteinaceous debris within the shunt tube.
