Brief Summary:
With regard to Cerebral Venous Thrombosis (CVT) importance as a life threatening disease, specific care is necessary, Known anti-coagulants have limitations.Vitamin K antagonists such as Warfarin, require laboratory monitoring and exact administration starting and maintenance dose. although Rivaroxaban(selective and direct Xa factor antagonist ) has no monitoring and no drug interaction.
