BACKGROUND AND OBJECTIVES: Aneurysmal subarachnoid hemorrhage is strongly associated with symptomatic cerebral vasospasm. This study aims to investigate whether a quantitative measure of aneurysmal subarachnoid hematoma by 3D Slicer is more valuable for vasospasm risk prediction compared with modified Fisher scale and the new scale by Eagles.
MATERIALS AND METHODS: We performed a retrospective research of Digital Imaging and Communications in Medicine format (DICOM) in aneurysmal patients treated at our institution from 2019 to 2020. Association between vasospasm and hematoma volume by 3D Slicer was explored by univariate and multivariate analyses. Value of risk prediction was compared through area under the receiver operator characteristic curve (AUC) among the modified Fisher scale, the new scale by Eagles, and hematoma volume by 3D Slicer.
RESULTS: Hematoma volume by 3D Slicer had a significant relationship with vasospasm both by one-way analysis of variance (ANOVA; F = 19.37, P < 0.001) and a binary logistic regression analysis (odds ratio [OR] = 1.05, P = 0.016). Hematoma volume by 3D Slicer had a significantly higher AUC (0.708; 95% confidence interval [CI]: 0.618-0.798, P < 0.001) than the modified Fisher scale and the new scale by Eagles. The optimal diagnostic threshold for hematoma volume by 3D Slicer was 15.98 ml, and the sensitivity and specificity were 73.5% and 58.6%, respectively.
CONCLUSIONS: Volume of aneurysmal subarachnoid hematoma measured quantitatively by 3D Slicer can improve the predictive value for symptomatic cerebral vasospasm.
