Peritoneo-vulvar catheter extrusion after shunt operation

Area of Science:

• Pediatric Neurosurgery
• Medical Device Complications
• Hydrocephalus Management

Background:

• Ventriculoperitoneal shunts are standard for hydrocephalus treatment in infants.
• Complications can arise, necessitating careful monitoring and management.
• Catheter extrusion is an infrequent but significant adverse event.

Observation:

• An unusual case of catheter extrusion was observed in a 6-month-old infant with hydrocephalus.
• The extrusion occurred through the external genitalia, specifically between the labium majus and labium minus.
• This event happened 5 months following the initial placement of a ventriculoperitoneal shunt.

Findings:

• Catheter extrusion is a rare but significant complication of ventriculoperitoneal shunts.
• The anatomical location of extrusion in this case was highly unusual.
• Early recognition and management are crucial for preventing further complications.

Implications:

• This case underscores the importance of careful surgical technique and post-operative monitoring in pediatric shunt placement.
• Further research may be needed to understand the specific risk factors for such extrusions.
• Improved patient monitoring protocols could potentially reduce the incidence of rare shunt complications.
