Time distribution of neurosurgical operations

According to the time urgency, neurosurgical procedures are divided into:
 * 1) emergent (so called procedures for vital indications) – cannot be delayed, operate immediately, there is an imminent threat to life, surgery has priority over pre-operative examination (eg. acute epidural hematoma),
 * 2) acute – can be delayed for a few hours to perform additional examinations (including internal pre-operative examination), surgery must be performed within 24 hours, longer delay may cause permanent damage to health (např. syndrome of cauda equina),
 * 3) planned (elective) – can be delayed, planned several weeks in advance (eg. meningeoma).
