Ventriculoperitoneal Shunt Malfunction Due to a Fibrous Capsule Obstructing the Peritoneal Catheter

Ventriculoperitoneal shunt obstruction is a common neurosurgical condition. Obstruction of the peritoneal catheter is less common than other sites of blockage in the system. We present a case of a ventriculoperitoneal shunt blockage caused by a sheath of hyalinised fibrous tissue that had encased the distal side slits of the peritoneal catheter resulting in sub-total blockage. The patient made a complete recovery following the removal of this fibrous tissue from the distal peritoneal catheter without the need to revise the entire shunt.
