Abstract

Background: Cerebral venous thrombosis is a severe disease and may lead to many serious sequelae. It is challenging to diagnose but it is a treatable disease. Objectives: To describe clinical features and to illustrate brain imaging. Materials and methods: Cross-sectional descriptive study in the patients who were diagnosed with cerebral venous thrombosis at Can Tho Central General Hospital from January 2021 to June 2022. Results: The most common clinical manifestations were headache (97.6%), limb weakness (59.5%), seizures (45.2%), vomiting (31%) and cognition disorders (23.8%). The patients^’ radiological findings were identified by magnetic resonance imaging (81%), computer tomography (11.9%) and digital subtraction angiography (7.1%). The proportion of the patients with brain damage accounted for 81% of the cases, in which intracranial hemorrhage was 47.6%, brain infarction accounted for 31%, subarachnoid hemorrhage was 19% and hemorrhagic infarct was 4.8%. The most common sites of thrombosis were superior sagittal sinus (85.7%), transverse sinus (54.8%) and sigmoid sinus (40.5%). Conclusions: Cerebral venous thrombosis has diverse clinical presentation. On brain imaging, the most common finding was intracranial hemorrhage. Dural sinus thrombosis happened highest in the superior sagittal sinus, followed by the transverse sinus and sigmoid sinus.
