Risk factors and predictors of outcomes in 243 Chinese patients with cerebral venous sinus thrombosis: A retrospective analysis.

Objectives: To investigate the risk factors and predictors of outcomes in a cohort of Chinese patients with cerebral venous sinus thrombosis (CVST), so as to provide a reference for customized clinical decision.

Patients And Methods: A total of 243 Chinese patients, diagnosed as a first CVST were enrolled in this retrospective study from March 2013 through April 2017. Risk factors and predictors of outcomes for CVST were summarized and analyzed by Chi-square test and logistic regression analysis.

Results: Of the 243 cases, obstetric cause (19.8%) was the leading risk factor for CVST, followed by infection (17.7%) and anemia (17.7%). Gender differences in the risk factors for CVST were analyzed, showing that obstetric cause was the top risk factor in female, while hyperhomocysteinemia (22.3%) was the top risk factor in male. In age subgroups, obstetric cause (26.3%) and anemia (17.6%) were more commonly observed in age ≤ 44 years and age > 44 years subgroup, respectively. The ratio of poor outcomes (mRS = 3-6) in this cohort was 23.0%, and central nervous system (CNS) infection was closely related to poor outcomes at discharge (p = 0.023).

Conclusion: The predominant risk factor for CVST, in this Chinese cohort, may still be obstetric cause in female and hyperhomocysteinemia in male. In addition, CNS infection may predict poor outcomes in CVST patients.
