Relationship Between Clinical Factors and the Risk of Cerebral Vasospasm Following Aneurysmal Subarachnoid...

Background/Objectives: Cerebral subarachnoid hemorrhage (SAH) from ruptured aneurysms poses significant morbidity and mortality risks. Among survivors, cerebral vasospasm can develop, increasing complications. This study investigates the relationship between blood parameters and the risk of vasospasm. Methods: We analyzed clinical data from patients with SAH-both with and without vasospasm-and healthy controls. Statistical analyses, including Spearman's rank correlation and univariate analysis, were conducted. Results: Significant differences were observed between patients with and without vasospasm. Elevated white blood cell counts, a higher neutrophil-to-lymphocyte ratio, and lower platelet counts showed a significant association with symptomatic vasospasm. Younger age and female gender were associated with a higher risk. Conclusions: These preliminary findings highlight the importance of specific blood parameters and demographic factors in assessing the risk of cerebral vasospasm in SAH patients, supporting early risk stratification and monitoring to improve outcomes; however, these results require validation in larger cohorts.
