Abstract:
A rare occurrence of spontaneous extrusion of a Denver peritoneal catheter through the right flank in a 14-year-old boy is reported. The firm texture and short length of the catheter coupled with its movements with respiration produced a hammer effect and eroded the abdominal wall. Disconnection of the peritoneal catheter from the chamber and pulling out the extruded catheter is suggested as a simple and effective method of removal of the shunt.
Insights
A Denver peritoneal catheter spontaneously extruded through a boy's abdominal wall. Disconnecting the catheter and pulling it out is a simple removal method for this rare shunt complication.
Area of Science:
- Pediatric Surgery
- Medical Device Complications
- Neurosurgery
Background:
- Peritoneal shunts are used to treat hydrocephalus.
- Complications can arise from indwelling medical devices.
Observation:
- A 14-year-old boy experienced spontaneous extrusion of a Denver peritoneal catheter.
- The catheter eroded through the abdominal wall due to its texture, length, and respiratory movement.
Findings:
- The firm texture and short length of the catheter contributed to a "hammer effect."
- This mechanical action led to abdominal wall erosion and catheter extrusion.
Implications:
- Suggests a simple disconnection and removal technique for extruded shunts.
- Highlights the importance of monitoring for rare peritoneal catheter complications.
