Objective To investigate the long-term prognosis of cerebral venous sinus thrombosis (CVST) and to identify the early predictors of poor outcome.
Methods We performed a prospective register study on the prognosis of CVST patients. All patients were followed up continuously. The primary endpoint was death or dependence as assessed by the modified Rankin Scale (mRS) score gt;2 at month 6. A multivariable logistic regression model was applied to identify the predictors of outcome.
Results A total of 52 CVST patients were included. The rates of recurrence and death at month 6 were 13.5% and 7.7%, respectively, and 29.9% of the patients were dead or dependent at month 6. The multivariable logistic regression analysis revealed that the predictors of death or dependence at month 6 were intracranial parenchymal lesion (OR=14.62, 95%CI 2.36 to 90.36) and delayed diagnosis (OR=13.14, 95%CI 1.90 to 90.84).
Conclusion In China, CVST is still a disease that may lead to death or dependence. Its long-term prognosis is relatively poor compared to that reported in western patients. This difference may due to the delayed diagnosis of CVST in China.
