title: Outcome of ruptured intra-cranial aneurysm treated by a deferred operation. Review of 345 consecutive cases treated over a period of 12 years.
abstract: This paper reports experience with 345 patients admitted to a neurosurgical department after an aneurysm rupture. At the time of admission, patients were separated into two groups: the patients unsuitable for planned surgery and called 'unoperable'; the patients planned for surgery and called 'operable patients' (328 patients). The general management attitude consisted of deferred surgery according to the clinical status of the patients and the risk of vasospasm and ischaemia. Of these, 18 died before the day of surgery, and are called 'operable and non-operated' patients. The cause of death was vasospasm and ischaemia in 10 cases and recurrence of haemorrhage in 8 cases. 310 patients were actually operated upon. Their final outcome was: good 70%, fair 9.6%, poor 7.7%, death 12.5%. This paper discusses the risk of SAH recurrence and the risk of vasospasm and ischaemia during the waiting time before surgery, in the attitude of deferred surgery which was elected in most cases of this series and compares the outcome with other published series.
