Key result
Diabetes, hypertension, and saccular aneurysm morphology are linked to high hemorrhage volume in SAH.
Why the study?
Significant risk factors influencing hemorrhage volume in patients with aneurysmal subarachnoid hemorrhage were not well identified.
What are the independent risk factors influencing hemorrhage volume in patients with aneurysmal subarachnoid hemorrhage?
Population
891 patients diagnosed with aneurysmal subarachnoid hemorrhage from multiple medical centers
Comparison
Patients with different risk factors influencing hemorrhage volume
Design
Multicenter retrospective cohort study

What are the independent risk factors influencing hemorrhage volume in patients with aneurysmal subarachnoid hemorrhage?
p-value: p=0.022 (diabetes), 0.047 (hypertension), 0.008 (saccular morphology)
Diabetes, hypertension, saccular aneurysm morphology, larger aneurysm size, and higher systolic blood pressure after onset are independent risk factors for increased hemorrhage volume in aneurysmal subarachnoid hemorrhage.
Li et al. (2025) conducted a cohort in aneurysmal subarachnoid hemorrhage (n=891). Diabetes, hypertension, and saccular aneurysm morphology was evaluated on high hemorrhage volume (p=0.022 (diabetes), 0.047 (hypertension), 0.008 (saccular morphology)). Diabetes (P=0.022), hypertension (P=0.047), and saccular aneurysm morphology (P=0.008) were independent risk factors for high hemorrhage volume in patients with subarachnoid hemorrhage.
