According to the modified Rankin scale (mRS) score at hospital discharge, the patients were classified into good prognosis (GP, mRS ≤ 2) groups and poor prognosis (PP, mRS> 2) groups. Logistic regression was used to identify factors associated with clinical outcomes.Results: Of the 290 patients, 35 were assigned to the PP group and 255 to the GP group. No significant difference in sex was observed between the two groups. Headache (76.21%) was the most frequent symptom of CVST, and local head and neck infection was the major comorbidity (26.21%). Approximately half of the patients (48.62%) had brain injury lesions < 1 cm, and the most commonly affected sinus was the lateral sinus (81.03%). Less-common headaches (odds ratio [OR]: 2.769, p=0.046), altered mental status (OR: 0.122, p< 0.001), hematologic disorder (OR: 0.191, p=0.045), and injury to multiple lobes (OR: 0.166, p=0.041) were associated with poor clinical outcomes.Conclusion: Headache was the most common and protective manifestation of CVST, and disturbances in consciousness were an important indication of poor clinical prognosis. Patients with hematologic diseases also tended to have poor outcomes. No significant correlation was found between the number and location of venous sinus thromboses and clinical prognosis; however, intracranial injury involving multiple lobes was often associated with poor prognosis.Keywords: cerebral venous sinus thrombosis, cerebral infarction, intracranial hemorrhage, hematologic disorder, prognosis
