{Abstract}: <B>BACKGROUND: </B>Ventriculoperitoneal (VP) shunt tube migration is recognized as an occasional complication; however, migration into the cardiac system is rare. The authors report a case of VP shunt tube migration into the heart and pulmonary artery and the safe removal of the tube.<BR><B>METHODS: </B>The patient had a VP shunt implanted for hydrocephalus after a subarachnoid hemorrhage. The screening chest radiograph taken a few months later showed the migration of the abdominal tube into the heart. Examinations revealed that the abdominal tube had migrated from the left subclavian vein, passed through the superior vena cava, right atrium and ventricle, and looped into the pulmonary artery. The patient had no symptoms; however, there were some risks, such as damage to the valves or fatal arrhythmia. The authors therefore decided to remove the tube. To avoid various intraoperative risks, in particular tube knot formation, the tube was removed under fluoroscopy with a guidewire inserted, which was 0.035 inches for the angiography catheter. The tube was successfully removed without any complications.<BR><B>CONCLUSIONS: </B>Knot formation can be one of the fatal complications of shunt tube removal. The authors' technique is an effective method for safe removal. https://thejns.org/doi/10.3171/CASE24127.
