Is it safe to treat cerebral venous thrombosis with oral rivaroxaban without heparin? A preliminary study from 20 patients

Abstract

ObjectivesNewer oral anticoagulants like rivaroxaban are increasingly becoming the mainstay of treatment in systemic thrombosis. However cerebral venous thrombosis (CVT) is conventionally treated with heparin followed by oral vitamin K antagonists. Currently very little information is available about the use of rivaroxaban in CVT. Rivaroxaban has been used only after the initial treatment with heparin in the available studies. Patients & methodsAll patients with CVT between January 2017 and June 2017 were initiated directly on oral rivaroxaban. Critically ill patients including those requiring surgical intervention were excluded. The modified Rankin scale was used to assess clinical severity and a scale of 0–1 was defined as excellent outcome. Recanalization was assessed at 3 months follow-up with MR angiography. Complications of the drug including bleeding episodes during treatment and at follow-up were noted. ResultsTwenty patients were initiated on rivaroxaban and followed up for a mean duration of 6 months. Eighty percent (16/20) were males and the mean age was 34.1 years. Associated cerebral hemorrhagic infarcts were seen in 11(55%).Outcome was excellent in 19(95%). Complete recanalization was noted in 12(60%) and partial recanalization in 8(40%). No complications emerged out of the drug use. ConclusionsIn clinically stable CVT rivaroxaban is safe and effective and may be used without previous heparin therapy. This can shorten the duration of hospitalization thereby decreasing the costs of treatment.
