RESUMEN
AIM OF THE STUDY: Oral anticoagulants, preferentially vitamin K antagonists (VKA), are recommended for 3-12 months in patients with cerebral venous sinus thrombosis (CVST). We present a series of patients with CVST treated with direct oral anticoagulants (DOAC). MATERIALS AND METHODS: We prospectively recruited 36 patients with CVST (aged 40.3 ± 9.2 years, 58.3% female) treated with DOAC based on the physician's or patient's preferences. Functional outcome was assessed with modified Rankin Scale. Recanalisation was assessed on imaging at 3-6 months post the event. Patients were followed for a median of 30 [interquartile range (IQR) 25-37] months. RESULTS: After use of heparin (median: 6 days; IQR 5-8.75), patients received dabigatran (150 mg bid, n = 16 or 110 mg bid, n = 2), rivaroxaban (20 mg qd, n = 10) or apixaban (5 mg bid, n = 8) for a median of 8.5 months (IQR 6.25-12). Complete or partial recanalisation was observed in 34 cases (94.4%). Three patients (8.3%) experienced major bleeding: menorrhagia on rivaroxaban (n = 2) and gastrointestinal bleeding on dabigatran (n = 1). A favourable functional outcome was observed in 24 (66.7%) patients, without any fatality. CSVT recurred in two patients (5.6%) and two venous thromboses developed in two other patients with inherited thrombophilia after anticoagulation withdrawal. CONCLUSIONS AND CLINICAL IMPLICATIONS: DOACs could be an alternative to VKA in CVST patients.
