Is a rare but important complication in patients with a ventriculoperitoneal shunt insertion.

Once the diagnosis is verified and if the cerebrospinal fluid CSF is sterile, just simply remove the peritoneal catheter and reposition a new one in the abdomen.

In case of CSF infection, the VP shunt can be removed and/or an external derivation can be made, and after treatment with antibiotics, a new VP shunt is placed in the opposite side of the peritoneum ¹⁾.
