Abstract
Although about 80% of patients with cerebral venous sinus thrombosis have a good prognosis, some patients develop severe complications and a small proportion do not survive. The study included patients who had been diagnosed with cerebral venous sinus thrombosis in our hospital from May 2008 to February 2014. Based on the modified Rankin Scale (mRS) scores at 3 months for outcome, the patients were divided into two groups: good prognosis (mRS score ≤ 2) and poor prognosis (mRS score > 2). Univariate and multivariate regression analysis were performed to identify significant prognostic factors for poor outcome. A total of 86 patients with cerebral venous sinus thrombosis, 54 males and 32 females, average age 41.3 years (range, 3-83 years), were enrolled. Of these 86 patients, 64 (74.4%) had a good prognosis and 22 (25.6%) a poor prognosis. Univariate analysis revealed that dyskinesia was a significant risk factor (factor with odds ratio >1) for poor prognosis. In multivariate analysis, the risk of poor prognosis in patients with dyskinesia was 23 times higher than for those without dyskinesia (p < 0.001). Thrombosis of the sinus transervus was found to reduce the risk of poor prognosis in both univariate and multivariate analysis. Most patients with cerebral venous sinus thrombosis have a good prognosis but patients with dyskinesia have a poorer prognosis.
