title: [Surgical treatment of múltiple intracraneal aneurysms].
abstract: BACKGROUND
  Surgical treatment of multiple intracranial aneurysms is always a complex task.
  
  
  OBJECTIVE
  To analyze aneurysms characteristics, therapeutic possibilities and surgical outcomes in a series of patients with multiple intracranial aneurysms.
  
  
  METHODS
  Among 514 patients with intracranial aneurysms, there were 113 with multiple aneurysms (21.5%) and 256 sacs: 244 located at the carotid system and 12 in the vertebrobasilar system. Patients were classified in three groups according to Orz criteria. Surgical treatment was performed in one or two stage operations. Patients were at I or II Grades of the World Federation Scale. The Glasgow Outcome Scale was used for evaluating surgical results.
  
  
  RESULTS
  Patients sacs rate was 2.3. The location of aneurysms was high in the posterior communicating artery and very low at the middle cerebral artery. 100% of the lesions in Orz group 1, 82% in group 2 and 33% in group 3 were operated on in one stage operation. Postoperative follow-up showed that 79 % of the patients made a completely recovery. Mortality rate was 4.4%.
  
  
  CONCLUSIONS
  Results were determined by the peculiar characteristics of this series, good preoperative condition and high proportion of one-stage operations.
