Direct Oral Anticoagulants for the Treatment of Cerebral Venous Thrombosis (DOAC-CVT)





About the study

DOAC-CVT is an international, prospective, phase IV cohort study investigating the safety and efficacy of direct oral anticoagulants (DOACs) compared to vitamin K antagonists (VKAs) in the treatment of cerebral venous thrombosis.

Patients may be included if they fulfill the following criteria:

  • Age >18 years at the time of CVT diagnosis

  • Radiologically confirmed CVT diagnosis (CT-venography, MRI or catheter angiography)

  • Oral anticoagulant treatment (DOAC or VKA) started within 30 days of CVT diagnosis (patient may initially be treated with heparin)

  • Informed consent for the use of coded data if required by local law.

Exclusion criteria are:

  • Anticoagulant treatment at the time of CVT diagnosis

  • Absolute contra-indication for use of DOACs: 

    • Pregnancy or lactation (post-partum women are eligible if they do not give breast-feeding)

    • Mechanical heart valve

    • Severe renal insufficiency (defined as an eGFR <15 ml/min)

    • Severe liver disease resulting in clinically relevant coagulopathy
