A 6-year-old boy had undergone ventriculoperitoneal (VP) shunt for acute hydrocephalus because of a brain tumor at the age of 11 months, and presented with vomiting and somnolence after the shunt malfunctioned 6 days after VP shunt reconstruction, during which the right external jugular vein was injured during the tunneling process and the peritoneal catheter was not fixed to the peritoneum with a purse string suture. Radiography revealed an abnormal route of the peritoneal catheter, suggesting that the distal VP shunt catheter had migrated into venous vasculature through the right external jugular vein. Computed tomography revealed that the peritoneal catheter had migrated into the internal jugular vein and the right atrium. At surgery, the peritoneal catheter was exposed through a small incision on the subclavicular region, was easily extracted from the internal jugular vein and the heart as there was no coiling or adhesion of the distal catheter to the vascular tissues, and was repositioned into the peritoneum with weak fixing between the subcutaneous tissues of the right subclavicular region and the right abdominal rectus muscle fascia as a temporary emergency measure. Peritoneal shunt migration into the internal jugular vein and the heart through the external jugular vein can be lethal because of pulmonary infarction or arrhythmia, and must be detected as soon as possible. Periodic follow-up radiography should be scheduled after VP shunt placement, even in the absence of symptoms.
