The complementary role of plain radiographs and radionuclide shuntography in evaluating CSF-VP shunts
1Department of Radiological Sciences and Diagnostic Imaging, Foothills Hospital, Calgary, Alberta, Canada.
Insights
Detached cerebrospinal fluid-ventriculoperitoneal shunt tubing migrated into the abdomen, creating a drain tract. Radiographic correlation is crucial during radionuclide shuntography to diagnose such complications.
Area of Science:
- Pediatric Neurosurgery
- Medical Imaging
Background:
- Ventriculoperitoneal shunts are standard treatment for pediatric hydrocephalus.
- Shunt malfunction is a common complication, with distal limb detachment a significant concern.
Observation:
- A case involving distal migration of detached shunt tubing into the abdomen is presented.
- This migration resulted in a patent subcutaneous tract allowing cerebrospinal fluid (CSF) drainage.
Findings:
- The detached distal tubing formed an unintended conduit for CSF.
- This highlights a rare but significant mode of shunt failure.
Implications:
- Accurate diagnosis of shunt complications requires careful radiographic assessment.
- Radionuclide shuntography necessitates radiographic correlation to identify distal limb migration and patent tracts.
Abstract:
Cerebrospinal fluid-ventriculoperitoneal shunts are often used in the treatment of hydrocephalus in children. Many complications can arise that may lead to shunt malfunction, including detachment of the distal limb of the shunt. A case is presented where such a complication occurred with distal migration of the detached tubing into the abdomen, which resulted in a patent subcutaneous tract through which cerebrospinal fluid could drain. The need for radiographic correlation at the time of radionuclide shuntography is stressed.
