Abstract

Objectives: To describe some clinical, risk factors, and brain imaging features of patients with cerebral venous thrombosis (CVT). Methods: A cross-sectional study was conducted on 40 patients with CVT at Military Hospital 103 from March 2019 to April 2024. Results: 40 CVT patients (0.38% of total stroke) had a mean age of 53.52 ± 19.03 years old and a female/male ratio of 1.1. Symptoms: Headache was the most common (87.50%); hemiplegia and vomiting occurred less frequently (52.50% and 47.50%); convulsions accounted for the lowest proportion (12.50%). The majority of patients admitted to the hospital did not have impaired consciousness (62.50%), and severe impaired consciousness accounted for 10.00%. There were 11 patients (27.50%) who did not find any risk factors related to CVT. The most common risk factors associated with CVT were alcoholism (20%), gout flare (15%), followed by chronic kidney disease, malignancy, Basedow's disease, and postpartum. Hypercoagulant factors associated with CTV: Protein C deficiency was the most common (17.50%), protein S deficiency and ATIII deficiency were less common (10.00% and 2.50%); most patients only lacked 1 of the 3 factors, combined deficiency of multiple factors was rare. Brain imaging included cerebral hemorrhage (40.00%), cerebral infarction (35.00%), and no brain parenchymal damage (25.00%). Thrombosis of the superior sagittal sinus and transverse sinus was the most common (40.00% and 25.00%). Conclusion: CVT accounted for a low rate of total stroke. Diagnosis of CVT based on clinical and laboratory tests is still difficult due to diverse and nonspecific signs.
