Ventriculoperitoneal shunt peritoneal catheter knot formation

Area of Science:

• Neurosurgery
• Pediatric Surgery
• Medical Device Complications

Background:

• Ventriculoperitoneal (VP) shunts are vital for treating pediatric hydrocephalus.
• Complications can arise at both cranial and abdominal insertion sites.
• Shunt infection and malfunction are significant concerns in pediatric neurosurgery.

Purpose of the Study:

• To report a rare case of VP shunt malfunction due to catheter knotting in a child.
• To highlight the diagnostic and management challenges associated with this specific complication.
• To review the existing literature on VP shunt catheter entanglement.

Main Methods:

• Case report of a pediatric patient with VP shunt infection and malfunction.
• Laparoscopic exploration to identify the cause of catheter tethering.
• Literature review of similar rare VP shunt complications.
• Surgical intervention involving new VP shunt insertion post-infection resolution.

Main Results:

• The peritoneal catheter was found to be tethered by a knot around the omentum within the abdominal cavity.
• The shunt infection and malfunction were successfully managed.
• A new VP shunt was implanted after the infection resolved.
• This complication, though rare, necessitates careful surgical technique and post-operative monitoring.

Conclusions:

• Catheter knotting is a rare but serious complication of VP shunts in pediatric patients.
• Laparoscopic surgery can be effective in diagnosing and managing intra-abdominal shunt issues.
• Early recognition and appropriate management are essential for favorable outcomes in pediatric hydrocephalus treatment.
• Further case reports and literature reviews are valuable for understanding and addressing rare shunt complications.
