Inclusion criteria

Inclusion criteria: The patients were acute subarachnoid hemorrhage patients admitted to Kansai Electric Power Hospital from 2015 to 2024.

Exclusion criteria

Exclusion criteria: Examples of indications for endovascular treatment and surgical cerebral artery treatment, patients who have completed hemostasis treatment for a ruptured cerebral aneurysm, who do not have severe motor system disease, circulatory system disease, or respiratory disease, and who have pre-symptomatic ADLs.

Design outcomes

Primary

Measure	Time frame
Safety outcomes will be determined by measuring middle cerebral artery systolic blood velocity, middle cerebral artery mean blood velocity, and middle cerebral artery/internal carotid artery systolic blood velocity ratio on days 3-5 after surgery.	—
