Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adults, children and neonates, regardless of gender with hydrocephalus.

You may qualify if:

  • Patient implanted with the Polaris® 24 adjustable valve system for the following reasons:
  • Primo implant of a valve shunt-based derivation system, or as a
  • Replacement of another valve -based shunt system, or
  • Endoscopic ventriculostomy (EVT) failure

You may not qualify if:

  • Confirmed or suspected infections along the length of the shunt (meningitis, ventriculitis, peritonitis, septicemia or bacteremia) or any infection present in any part of the body
  • Patient on anticoagulant therapy, or presenting with bleeding diathesis, or with haemorrhagic CSF, as the presence of blood in the system could lead to an obstruction in the system
  • Ventriculo-atrial shunts in patient suffering from congenital cardiopathies or other malformations of the cardio-pulmonary system
