Treatment Outcomes of Direct Oral Anticoagulants in Cerebral Venous Thrombosis in Vietnam

This prospective, single-arm observational cohort study aims to evaluate the real-world effectiveness and safety of direct oral anticoagulants (DOACs), specifically dabigatran or rivaroxaban, in patients with cerebral venous thrombosis (CVT). The study will be conducted at Bach Mai Hospital, a national tertiary stroke referral center in Hanoi, Vietnam. A minimum of 69 adults with radiologically confirmed CVT will be enrolled between June 2025 and June 2027. All participants must have received therapeutic-dose heparin during the acute phase and will be transitioned to a DOAC within 5 to 15 days, per physician judgment. All treatments are part of routine care; no investigational drugs are used. The primary outcome is a composite of major bleeding (per ISTH criteria) or recurrent venous thromboembolism (VTE) within 6 months. Secondary outcomes include: functional outcome (Modified Rankin Scale), venous sinus recanalization, all-cause mortality, serial D-dimer levels, post-CVT chronic headache, health-related quality of life (EQ-5D-5L), clinically relevant non-major bleeding (CRNMB), symptomatic recurrent VTE, arterial thrombotic events, and early treatment discontinuation. This study aims to generate real-world data supporting DOAC use in CVT, particularly in Asian populations where prospective evidence is limited.
