Decompressive Surgery in Patients with Poor-grade Aneurysmal Subarachnoid Hemorrhage: Clipping with Simultaneous Decompression Versus Coil Embolization Followed by Decompression.

In this study, despite aggressive surgical and endovascular management for elevated ICP, there were high rates of adverse outcomes and mortality in poor-grade aSAH. Despite poor outcomes overall, early coil embolization followed by decompression surgery could lead to more favorable outcomes in patients with poor-grade aSAH.
