• shunt
  • The ETV procedure is used as an alternative to a cerebral shunt mainly to treat certain forms of noncommunicating obstructive hydrocephalus (such as aqueductal stenosis), but since the ETV was introduced as an accepted treatment modality the range of etiologies for which it is used has grown significantly. (wikipedia.org)
  • The surgical treatment options for hydrocephalus are, as previously mentioned, implantation of a cerebral shunt and ETV. (wikipedia.org)
  • A two years old patient with hydrocephalus due to aqueductal stenosis, without previous shunt would have an 80% chance of success (40 for age + 30 for etiology + 10 for no previous shunt = 80). (wikipedia.org)
