title: Surgical treatment of multiple intracranial aneurysms.
abstract: OBJECTIVE
  To analyze the treatments of multiple intracranial aneurysms.
  
  
  METHODS
  Natural conditions of 123 patients and treatments of multiple intracranial aneurysms were analyzed retrospectively.
  
  
  RESULTS
  Of 123 patients with multiple intracranial aneurysms. 101 harbored two aneurysms; 16, three; 4, four; 2, more than four. The female-to-male ratio was nearly 1.7:1(78 females to 45 males). The age range was from 11 to 74 with a mean of 50.37 years. Thirty(24.4%) patients received conservative treatment. 91(74.0%) neurosurgical treatment, 82 (90.1%) patients obtained excellent or good outcomes.Six(4.9%) endovascular embolization, one hemiparesis and one paralysis was observed.
  
  
  CONCLUSIONS
  Based on our results, we recommend that, if possible, all multiple aneurysms should be treated in one stage or multiple sessions. With Navigation and Keyhole Techniques, the injury and risk of surgery have been decreased, and outcomes have improved. Perfection of the endovascular occlusion technique also improves the prognosis of this disease.
