title: Hydrocephalus: an underrated long-term complication of microvascular decompression for trigeminal neuralgia. A single institute experience.
abstract: Hydrocephalus is a common complication of posterior fossa surgery, but its real incidence after microvascular decompression (MVD) for idiopathic trigeminal neuralgia (TN) still remains unclear. The aim of this study was to focus on the potential association between MVD and hydrocephalus as a surgery-related complication.
  
  
  
  All patients who underwent MVD procedure for idiopathic TN at our institute between 2009 and 2014 were reviewed to search for early or late postoperative hydrocephalus.
  
  
  
  There were 259 consecutive patients affected by idiopathic TN who underwent MVD procedure at our institution between 2009 and 2014 (113 men, 146 women; mean age 59 years, range 30-87 years; mean follow-up 40.92 months, range 8-48 months). Nine patients (3.47 %) developed communicating hydrocephalus after hospital discharge and underwent standard ventriculo-peritoneal shunt. No cases of acute hydrocephalus were noticed.
  
  
  
  Our study suggests that late communicating hydrocephalus may be an underrated potential long-term complication of MVD surgery.
