Thrombolysis or Anticoagulation for Cerebral Venous Thrombosis: Rationale and Design of the TO-ACT Trial

Abstract

The primary endpoint is the modified Rankin score (mRS) at 12 months, with a score ≥2 defined as poor outcome. Secondary outcomes are six-months mRS, mortality, and recanalization rate. Major intracranial and extracranial hemorrhagic complications within one-week after the intervention are the principal safety outcomes. Results will be analyzed according to the 'intention-to-treat' principle. Blinded assessors not involved in the treatment of the patient will assess endpoints with standardized questionnaires.
