title: [Intracranial aneurysms difficult to be treated by endovascular interventional therapy: report of 27 patients].
abstract: OBJECTIVE
  To analyze the characteristics of aneurysms difficult to be treated by endovascular interventional therapy and report the results of operation.
  
  
  METHODS
  27 patients with 33 intracranial aneurysms transferred from the ward of interventional therapy, 7 males and 20 females, aged 47 (27-67), accepted microsurgical operation, The neck, volume, aspect ratio and blood vessel condition of the aneurysms were analyzed.
  
  
  RESULTS
  The aneurysms difficult to be treated by endovascular interventional therapy included those with wide neck (>4 mm), large volume (maximal diameter>or=8 mm), and failure in endovascular maneuvers (because of flexed blood vessel and severe vasospasm). The total outcome of operation was good and no death occurred.
  
  
  CONCLUSIONS
  Some aneurysms difficult to be treated by endovascular interventional therapy should be treated by microsurgical operation, which will get a better result.
