SUBARACHNOID HEMORRHAGE BEYOND 65 YEARS - A RETROSPECTIVE ANALYSIS OF65 ANEURYSMS AMONG 72 CASES OF ALL ORIGINS

For this study, we reviewed a series of 564 consecutive SAH among whic h 72 cases (12.7 %) were older than 65 years. Etiology of SAH was : ar terial aneurysms (65), arteriovenous malformations (1), unknown origin (6). Among the 65 aneurysms, 28 operated cases were between 65-69 yea rs old. One year after surgery, the results are. GOS 1 and 2 : 22 case s (57 %); GOS 3 :4 cases; GOS 5 : 13 cases. In the non operated group, 19 cases died (73 %) and among the alive patients, one was GOS 2 (4 % ), 5 GOS 3 and 1 GOS 4. In the operated group, mortality is similar to other published series. In the non operated group, mortality is unsur prisingly higher (73 %) than in the operated group, but also than in t he literature. An explanation could be found with analyses of the inco me of our patient whose many are not refered cases from other hospital . Our analysis confirmed that the severity of SAH after 65 years is in creasing. The raise of anterior communicating aneurysms location is de monstrated. Operative indication and timing are dependant of neurologi cal grading, general condition and secundarily of the location and ana tomy of the aneurysm.
