Peritoneal catheter repositioning

see also Peritoneal catheter placement.

Whenever suspected it should be confirmed by imaging, followed by open exploration and repositioning of the peritoneal catheter 1).

In case of suspected ventriculoperitoneal shunt infection, the ventriculoperitoneal shunt is removed and replaced by an external ventricular drain. Antibiotics are started and adjusted to the results of the CSF culture. If there is no direct sign of infection, only the distal catheter is externalized and antibiotics are introduced until the shunt infection is treated. Depending on the peritoneal absorption state, the distal catheter is replaced in the abdominal cavity or in the atrium, the pleural space, or the gallbladder if there is no suitable place for repositioning. If the peritoneal state allows it, a laparoscopic procedure is recommended to avoid peritoneal adhesion formation increasing the recurrence rate of CSF pseudocyst 2).
