Outcomes of cerebral venous thrombosis in Al-Yarmook teaching hospital

Abstract

Background: Cerebral venous thrombosis (CVT) is a disease with multiple causes and has a low incidence rate. Seizure is one of the most common complications of CVT. The rate at which seizure occurs following CVT and the risk factors associated with that occurrence is a debated issue. Objectives: The aim of this study was to evaluate the incidence of seizure and its associated and risk factors for patients with CVT. Subjects and Methods: This was an observational study that included a total of 30 adult patients with CVT. Data, including age, sex, clinical manifestations such as fever, headache, vomiting, altered consciousness, and focal neurologic signs, such as sensory disturbances, were collected. Imaging findings that included hemorrhagic lesion, infarction, and thrombus site were also reported. Patients were followed up for 6 months from the initial diagnosis to recognize the development of seizures. Results: Within 6 months of follow-up, 13 (43.3%) patients developed generalized seizures, which was the most common type of CVT. The superior sagittal sinus (SSS) occlusion was recognized in 84.62% of patients with seizures and 48.06.5% in patients without seizures. Similarly, the right lateral sinus was occluded in 84.62% of patients with seizures as compared with 41.18% among those without seizures. Contraceptive use was reported in 61.54%of patients with seizures versus 17.65% in those without seizures with a significant difference. Conclusion: The involvement of SSS and lateral right sinus occlusion and use of contraceptives could be warning signs and a risk factor for the development of seizures in patients with CVT.
