Long-term outcomes of poor-grade aneurysmal subarachnoid hemorrhage: a multicenter observational cohort study

Although there has been a downward trend in recent years, the long-term mortality rate for patients with poor-grade aSAH has remained significantly high at 51.1%, with 21.4% of survivors being dependent. Active aneurysm treatment, to the extent possible, is crucial for improving the prognosis of these patients.

Abstract

Although there has been a downward trend in recent years, the long-term mortality rate for patients with poor-grade aSAH has remained significantly high at 51.1%, with 21.4% of survivors being dependent. Active aneurysm treatment, to the extent possible, is crucial for improving the prognosis of these patients.
