Dural Arteriovenous Fistulas With or Without Cerebral Venous Thrombosis: A Cross-Sectional Analysis of 511 Patients

Abstract

BACKGROUND AND OBJECTIVES: Recent studies suggest a bidirectional relationship of dural arteriovenous fistula (DAVF) with cerebral venous thrombosis (CVT). We aimed to compare the characteristics of patients with DAVF with or without CVT and to analyze the risk factors for the coexistence of CVT in a DAVF population. METHODS: A total of 511 adult patients with DAVF were enrolled consecutively in our hospital from February 2019 through November 2022. Demographic data, clinical manifestations, and imaging characteristics were reviewed in detail. The patients with DAVF were divided into two groups: DAVF with CVT (DAVF-CVT) group and without CVT (DAVF alone) group. Univariate logistic regression and multivariate logistic regression were used to analyze the risk factors for the coexistence of CVT and DAVF. RESULTS: CVT was found in 19.8% of patients with DAVF. In univariate analysis, compared with the DAVF-alone group, the DAVF-CVT group was more likely to have tinnitus (P =.001), blurred vision (P
