Warfarin versus factor Xa inhibitors in the long-term treatment of cerebral venous sinus thrombosis a single-center retrospective analysis.

Long-term anticoagulation in the treatment of Cerebral Venous Sinus Thrombosis (CVST) has revolved around the use of warfarin. The relatively recent introduction of Direct Oral Anticoagulants (DOACs), such as Factor Xa inhibitors, in treating CVSTs promises to offer numerous patient benefits. We aimed to examine the efficacy of Factor Xa inhibitors in comparison to warfarin in the long-term treatment of CVSTs. A single-center retrospective analysis was conducted in which 49 eligible patients having presented with a first-time CVST were identified. Long-term anticoagulation was achieved with Warfarin (n = 23) or Factor Xa Inhibitors (n = 26; Apixaban or Rivaroxaban). Outcomes of interest were improvements in patient functional status, modified Ranking Scores (mRS), and radiographic improvement/resolution in sinus thromboses. Secondary comparisons included complication rates, particularly recurring venous thrombotic events. Patient mRS scores by 7-to-18-month follow-up all fell within the extremely favorable range of 0-1 regardless of the long-term anticoagulant (P-value = 0.3591). Proportion of patients with radiographic improvement/resolution of thrombosed sinuses trended towards being higher in the Factor Xa Inhibitor group at the <12-month period, 69.2%, compared to 33.3% with Warfarin (
