*Radiographic “shunt series” indicated the distal catheter to have broken.
†In admissions 5, 47, and 48, a preceding CSF tap indicated infection; in all three cases the VP shunt was replaced with an external ventricular drain. Only admission 5 presented with fever.
‡At surgery it was found that the distal end of the catheter was in an extraperitoneal position.
