Abstract:

Objective

To identify independent risk factors for intraventricular hemorrhage development caused by ruptured aneurysm.

Methods

From January 2017 to August 2020, the clinical and imaging data of patients with aneurysmal subarachnoid hemorrhage were analyzed retrospectively. Univariate analysis and multivariate logistic regression analysis were performed to identify the risk factors for intraventricular hemorrhage from ruptured aneurysm.

Results

A total of 596 patients who met the criteria were enrolled in this study, and intraventricular hemorrhage was present in 198 patients (33.2%).Univariate analysis showed that age, history of diabetes mellitus, aneurysm size, and aneurysm located at posterior circulation were related to intraventricular hemorrhage. Multivariate logistic regression analysis showed that increasing age (OR = 1.017, 95%CI: 1.001-1.033, P = 0.037), history of diabetes mellitus (OR = 2.545, 95%CI: 1.244-5.208, P = 0.011), increasing aneurysm size (OR = 1.101, 95%CI: 1.031-1.177, P = 0.004) and location in the posterior circulation (OR = 1.863, 95%CI: 1.104-3.144, P = 0.02) were independent risk factors for intraventricular hemorrhage development due to ruptured aneurysm.

Conclusions

Higher age, history of diabetes mellitus, increasing aneurysm size and location in the posterior circulation are associated with the occurrence of aneurysmal intraventricular hemorrhage.
