In patients with aneurysmal subarachnoid hemorrhage (aSAH), it is unclear whether aneurysm treatment <24 h after ictus results in better outcomes than treatment 24-72 h after aSAH. We studied whether aneurysm occlusion <24 h is associated with better outcomes than occlusion 24-72 h after aSAH. ⋯ Our results suggest that aneurysm occlusion can be performed in day time within 72 h after ictus, instead of on an emergency basis. However, due to the retrospective, non-randomized design of our study, our results cannot be considered as definitive evidence.
