"Aneurysm size and PHASES and ELAPSS scores were independent predictors of hemorrhage."

"Among patients with a PHASES score < 8 or an ELAPSS score < 15, no aneurysm-related death or aneurysm rupture occurred."

"Survivors of aSAH are at excessive risk of suicide death in comparison with the general population."

"Given that this risk seems to be the highest among young individuals and during the first year after aSAH, early assessment and management of psychological distress, especially in young survivors of aSAH may be warranted."

"...compared the clinical outcomes of endovascular treatment (EVT) vs surgery for patients with ruptured intracranial aneurysms excluded from previous randomized trials. This underpowered study showed longer hospitalizations but better 1-year angiographic results with surgery"

"The primary clinical outcome, death or dependency at 1 year, was similar for EVT and surgery. This study provides the first randomized data on the surgery/embolization controversy since the last trial was completed 15 years ago."
