PICCs are safe and may be used for prolonged periods. In our center, the rates of infectious complications are lower than for tunneled central venous catheters. Accidental dislodgement is not uncommon and may be prevented by use of sutures, occlusive dressing, and education of patients, families, and medical staff.

A 3-year-old boy experienced 10 recurrent gram-negative ventriculoperitoneal shunt (VPS) infections with identical strains over a 17-month period. Multiple cranial MRI and CT scans to identify a retained foreign body were negative. CT myelography and pressure infusion radionuclide cisternography were also unhelpful. Ventriculoscopy revealed a small retained foreign body which was successfully removed, and cultures subsequently yielded gram-negative organisms identical to the previously identified bacteria by pulsed field gel electrophoresis. No further infections were noted after removal of the retained fragment. Exploratory ventriculostomy should be considered in patients with recurrent VPS infections where other techniques fail to reveal a cause.
