title: Progress in the management of patients with aneurysmal subarachnoid hemorrhage: a single hospital review for 20 years. Part II: Aged patients.
abstract: BACKGROUND
  We have reported improvement in the outcome of the younger patients with aneurysmal subarachnoid hemorrhage in the preceding article. The purpose of this article is to study if the same management protocol has simultaneously benefited the elderly patients.
  
  
  METHODS
  One hundred twenty-nine patients with aneurysmal subarachnoid hemorrhage, over 70 years old, who were consecutively admitted to Kagawa Prefectural Central Hospital from July 1972 to December 1992, were reviewed. Patient grouping and outcome evaluation were the same as those of younger patients.
  
  
  RESULTS
  Changes in treatment protocol in this period, which were similar to those of the younger counterparts, resulted in an increased number of patients who actually underwent aneurysm clipping. Although the outcome evaluated at 6 months after initial hemorrhage was significantly poorer than that of the younger counterparts, there have been some improvements during the study period. Patients in good clinical condition at 6 months' follow-up (Glasgow Outcome Scale: Good Recovery) increased from 37.5% to 42.9% in grades I-II and from 0% to 23.1% in grade III, respectively.
  
  
  CONCLUSIONS
  The improvement in the outcome of elderly patients was less remarkable than that observed in younger patients. Significantly higher incidence of preoperative rebleeding and postoperative symptomatic vasospasm has proven to be the major cause of mortality and major morbidity at present. More careful and sophisticated perioperative care is required in elderly patients with aneurysmal subarachnoid hemorrhage.
