ABSTRACT
Background:
Cerebral venous thromboembolism (CVT) poses a significant risk of venous infarction and haemorrhage, which can lead to neurological deficits and, in severe cases, even death. The optimal treatment regimen for patients with CVT remains unclear.Methods:
MEDLINE, Embase, Google Scholar, Web of Science (WoS), and Cochrane Central databases were searched for randomized controlled trials (RCTs) and observational studies assessing the efficacy and safety of rivaroxaban in patients with CVT. All-site venous thromboembolism (VTE), risk of clinically relevant non-major bleeding, incidence of partial recanalization, complete recanalization and major haemorrhage were among outcomes of interest. Mantel-Haenszel weighted random-effects model was used to calculate relative risks (RRs) with 95% CIs.Results:
The analysis included 1 RCT and 3 observational studies containing 211 patients. Compared to vitamin K antagonists (VKAs), rivaroxaban did not significantly decrease the all-site VTE [RR 0.31 (95% CI 0.01, 8.43); P=0.49, I2=0%]. Compared with VKAs, patients on rivaroxaban did not show a significantly reduced risk of recurrent cerebral venous thrombosis. In terms of incidence of partial recanalization, there was no discernible difference between rivaroxaban and VKAs [RR 0.90 (95% CI 0.66, 1.22); P=0.49, I2=0%]. There was no discernible difference in incidence of complete recanalization [RR 0.98 (95% CI 0.32, 3.03); P=0.97, I2=28%] and incidence of major haemorrhage [RR 0.19 (95% CI 0.01, 4.54); P=0.30].Conclusion:
Rivaroxaban was found to have similar efficacy to VKAs. Due to its lower risk of severe bleeding and no need for INR monitoring, rivaroxaban may be a preferable treatment option for CVT.
