Abstract:From January 1996 to December 2005, we treated 339 patients with ruptured intracra- nial aneurysms and investigated the patient’s backgrounds, preoperative Hunt & Kosnik grade,  site  of  ruptured  aneurysms,  the  presience  of  symptomatic  vasospasm,  normal  pressure  hydro- cephalus  and  the  Glasgow  Outcome  Scale  on  discharge,  retrospectively. The  patient’s  back- ground  and  preoperative  Hunt  &  Kosnik  grade  were  same  as  the  ones  reported  pre- viously. Regarding the site of ruptured aneurysms, ACA was less frequent than ICA. The in- cidence  of  symptomatic  vasospasm  did  not  increase  in  proportion  to  the  severity  of  the  SAH  grade, but normal pressure hydrocephalus did increase in proportion to the severity of the SAH  grade. Concering  GOS  on  discharge  it  was  good  in 75%  of  our  cases. Although  the  patients  with  aneurysms  of  posterior  circulation  tended  to  have  an  increased  severity  of  the  SAH,  their  prognosis  was  the  same  as  that  for  patients  with  aneurysms  of  the  anterior  circula- tion. Concerning  GOS  on  discharge,  it  improved  during  the  last 5 years  in  comparison  to  the  former 5 years. The reason for this might related to the introduction of GDC embolization, and  new neuroprotective drugs.
