What complications are possible following hemispherectomy?

  • Most children have excellent long-term results following hemispherectomy with no unexpected adverse outcomes. Occasionally, however, some complications may occur.
  • Early complications, which occur either during the intraoperative or immediate postoperative period include intraoperative blood loss, electrolyte changes, hypothermia and aseptic meningitis.
  • Late onset complications can occur months or years after the hemispherectomy. These hydrocephalus and recurrence of seizures, though rare, can be life threatening and need to be treated urgently.
