title: Protrusion of a peritoneal catheter via abdominal wall and operated myelomeningocele area: a rare complication of ventriculoperitoneal shunt.
abstract: BACKGROUND
  Ventriculoperitoneal shunting is mostly used in the treatment of hydrocephalus, and many complications have been reported with this method. These complications include obstruction, mechanical shunt failure, infection, and abdominal complications. Abdominal complications include intestinal obstruction, volvulus, peritonitis, peritoneal cyst, cerebrospinal fluid ascites, as well as migration of the distal catheter via the intestinal tract, umbilicus, scrotum, and vagina. Various mechanisms have been suggested with regards to the catheter migration.
  
  
  METHODS
  We present a case of a 21-month-old female patient who had myelomeningocele at birth. She underwent repair of the myelomeningocele at the age of 10 days. After 4 months, cranial computed tomography revealed hydrocephalus, and ventriculoperitoneal shunt was placed. Because of shunt dysfunction, a new ventriculoperitoneal shunt system was installed at the age of 12 months. Eight months later, her mother noticed the protrusion of peritoneal catheter via abdominal wall and repaired myelomeningocele area. Revision of the lower end of the shunt was done, and myelomeningocele area was repaired again.
  
  
  CONCLUSIONS
  We report a unique patient with the protrusion of the distal catheter through repaired myelomeningocele area and abdominal wall in the lumbar region.
