Ventriculo - Gallbladder shunt

Area of Science:

• Neurosurgery
• Medical Devices
• Fluid Dynamics

Background:

• Hydrocephalus management often involves shunts, but complications like shunt failure and infection necessitate alternative solutions.
• Ventriculoperitoneal (VPS) and ventriculoatrial (VAS) shunts carry risks, including peritoneal adhesions and endocarditis, limiting their long-term efficacy.
• The ventriculo-gallbladder shunt (VGS) is explored as a last-resort option for complex hydrocephalus cases.

Observation:

• A 43-year-old male with a 12-year history of hydrocephalus and chronic fungal meningitis experienced multiple VPS failures.
• Following VPS failure, a ventriculoatrial shunt (VAS) was placed but later removed due to suspected endocarditis.
• A ventriculo-gallbladder shunt (VGS) was implanted, showing no need for revision in six months.

Findings:

• The gallbladder's high absorptive capacity (1500 cc/day) exceeds cerebrospinal fluid (CSF) production, making it a suitable diversion site.
• VGS is effective in cases where VPS is contraindicated due to adhesions or when VAS is not feasible.
• The case demonstrates successful VGS implantation as an alternative to conventional shunts.

Implications:

• VGS presents a promising alternative for patients with refractory hydrocephalus and failed conventional shunts.
• This approach expands treatment options for complex hydrocephalus cases, potentially reducing re-intervention rates.
• Further research into VGS long-term outcomes and broader applicability is warranted.
