title: Clinical Analysis of Results of Shunt Operation for Hydrocephalus Following Traumatic Brain Injury.
abstract: OBJECTIVE
  Ventricular enlargement following head injury is a frequent finding but cases requiring shunt operation are rare. The incidence and developing factors of post-traumatic hydrocephalus (PTH) have been variously reported, but studies for factors influencing outcomes of shunt operation for PTH are rare. The incidence of PTH requiring shunt operation, causing injuries, and factors influencing outcome of shunt operation need to be identified.
  
  
  METHODS
  In total, 1,142 patients suffering from traumatic brain injury (TBI) between January 2007 and December 2012 were admitted to our department. Of them, 23 patients underwent shunt operation for diagnosed PTH. In this clinical study, we reviewed retrospectively our TBI database and in the 23 patients, we evaluated outcomes with Glasgow Outcome Score just before the operation, at 14 days, 3 months, and 6 months according to initial Glasgow Coma Scale (GCS) score, interval time between shunt operation and trauma, and lumbar cerebrospinal fluid (CSF) pressure.
  
  
  RESULTS
  The incidence of PTH treated with shunt operation was 2.01%. Subdural hematoma (SDH) was the most common preceding head injury. The outcomes of shunt operation were not related with lumbar CSF pressure or interval time from trauma, but initial GCS score correlated with the outcome.
  
  
  CONCLUSIONS
  In present study, 2.01% of TBI patients underwent shunt operation. SDH was the most common preceding injury. Admission GCS score was related to the outcome of shunt operation. However, there were no correlation between the outcome of shunt operation and initial lumbar CSF pressure or interval time of shunt operation after the trauma.
