title: [Microsurgical treatment of proximal anterior cerebral artery aneurysms].
abstract: OBJECTIVE
  To explore clinic characteristics of proximal anterior cerebral artery aneurysms and analyzed operative techniques.
  
  
  METHODS
  A review was performed of a total of 362 patients whose aneurysms were surgically treated from June 1995 to December 2003, the morbidity of A(1) aneurysms was 2.2%. To reviewed clinical data of 8 proximal anterior cerebral artery aneurysms patients.
  
  
  RESULTS
  All of the aneurysms developed at the takeoff point of perforating arteries, the recurrent artery of Heubner in three cases, the medial proximal lenticulostriate artery in five cases. Six cases aneurysms projected posteriorly, two cases projected inferiorly in the surgical field. The shape of the aneurysms was saccular in all cases and diameter no larger than 5 mm in six cases. Patients were clipped satisfactorily, excellent condition in 7 patient, good condition in one.
  
  
  CONCLUSIONS
  It is important to preserve the perforating arteries and use suitable clip by avoiding cerebral ischemia.
