Bowel perforation (rare)

What it is

Bowel perforation is a rare complication of a ventriculoperitoneal (VP) shunt in which the distal catheter erodes through the wall of the bowel (intestine). Although uncommon, it is important because it can lead to infection and requires prompt treatment.

Understanding Bowel perforation (rare)

In rare cases, the abdominal end of a VP shunt can, over time, erode through the bowel wall. This can introduce bowel contents and bacteria into the shunt system, risking infection (including ventriculitis or meningitis), and sometimes the catheter can even protrude from the body. Signs can be subtle or relate to infection or shunt malfunction. Because of the infection risk, bowel perforation requires prompt treatment — typically removing or externalizing the shunt, treating the infection, repairing the bowel as needed, and later replacing the shunt if required. While bowel perforation is rare, awareness of it is part of understanding the range of possible shunt complications, and any signs of infection or abdominal problems in a shunted person warrant evaluation.

Why it matters

Understanding bowel perforation helps families recognize that, while rare, serious abdominal complications of a VP shunt can occur, and why signs of infection or abdominal problems warrant prompt evaluation.
