A complicated case of ventriculoperitoneal shunt migration into the right heart ventricle after malresorptive hydrocephalus: illustrative case.

ABSTRACT:

Background

Malresorptive hydrocephalus occurs when CSF is inadequately absorbed, often following surgery. Ventriculoperitoneal (VP) shunt implantation is a well-established intervention to manage hydrocephalus by diverting excess CSF to the peritoneal cavity.

Observations

This case report describes a rare complication following VP shunt implantation in a 62-year-old male patient with malresorptive hydrocephalus after prior aneurysm clipping. Despite laparoscopic intraoperative confirmation of correct intraperitoneal VP shunt catheter placement, postoperative imaging revealed migration of the shunt catheter into the right heart ventricle, having perforated the internal jugular vein during its insertion. The catheter formed a knot within the venous system, requiring a combined
