Background

Early functional status at hospital discharge is a clinically relevant outcome after aneurysmal subarachnoid hemorrhage (aSAH), but early prognostic assessment remains challenging.

Methods

In this retrospective single-center cohort study, 252 consecutive adults with aSAH were screened, and 144 endovascularly treated patients with available admission complete blood count with differential were included.

n = 144 endovascularly treated patients

Results

higher neutrophil-to-lymphocyte ratio at admission cuts the odds of independent discharge

adjusted OR 0.47 (95% CI 0.24 to 0.90)

null 1

0.24

0.90

CI excludes the null - significant

More results

Forty-one patients (28.5%) achieved discharge independence.

Other inflammatory indices did not significantly improve discrimination.

Conclusion

In this single-center retrospective cohort of endovascularly treated patients with aSAH, admission neutrophil-to-lymphocyte ratio was independently associated with discharge independence and provided modest incremental prognostic information beyond established neurological severity scales.
